RE: Resi fridges in more and more units

Shame that the Danfoss powered 12-24v DC compressor fridges are so expensive, because they will use about half the electricity as a residential fridge on an inverter will. I got a 1.8 cubic foot fridge with a danfoss BD35f compressor, that has extra insulation, and a very well ventilated condenser, and it averages 0.62 Amp hours per hour consumption in 75F ambients as I use it, and my Door seals are questionable and could easily be improved upon. My one 800 watt MSW inverter uses 0.68 AH each hour, turned on, powering nothing.

RE: SLI battery maintenance

2 amps was able to get the battery to 16.2v? My flooded marine batteries required about 5 amps per 100Ah after hours at 14.4-.7, to get upto 16v. I've also EQ's a not very old flooded group 27 starting battery that was deepcycled often and rarely charged anywhere near full, and it required 4 amps to get to 16.2v and eventually settled to 2.5 amps before amps required to maintain 16.2v began rising again. Was never able to restore Sg on that battery and it is apparently still continuing to be deep cycled over a few week timespan by someone who repeats a battery's age over and over as to whether it is still good or not.. The EZ red and similar plastic hydrometers say they are temp compensated, but I do not believe it. During EQ charging the electrolyte gets warmer. My float readings with a turkey baster glass style hydrometer would often stay the same, but when factoring in the temp compensation, the EQ was still increasing SG and i would keep going until it did not or amps required to hold 16v would start rising instead of tapering.

RE: Antenna reception diminishes after initial channel search

I get this too, especially if I run an autoscan right at sundown. At sundown i get all sorts of stations that disappear shortly after. My laptop power supply knocks out a very strong channel whether I use the DC to DC or the AC to DC, but the AC to DC also requires the inverter which causes more rfi. Some LED's knock out some other channels. I try and use some Deoxit d5 every so often on the f Connectors, especially those outside. Sometimes it helps ither times it does not.

RE: Wfco amp test.. What are you pendant guys getting?

When I joined this forum I had a very poor understanding of the relationship between volts and amps. I thought a charging source could manipulate each of those individually and had complicated algorithms that could somehow sense the battery capacity and adjust accordingly. This was extremely foolish and ignorant. After trying to fins some charging source which would be reliable, and could deal with different types of future batteries, and with the help of Mex, I Now use a 40 amp adjustable voltage Meanwell powersupply and use a 90 Amphour AGM battery for both engine starting and house loads. though I have enough room for 345Ah of total capacity. The adjustable voltage power supply has been modified by me with a 10 turn potentiometer and more heatsinking and ventilation, and I can set it to any voltage between 13.12 and 19.23v and can, if it has to, deliver 40 amps continuously at those chosen voltages. I have a wattmeter/ammeter on the output, as well as a shunted ammeter/Ah counter reading amps into or out of battery. SO I can always see how much amps the power supply is supplying, at what voltage, and how much of that is going into my battery as compared to how much of that is powering DC loads. This removes ALL mystery as to what is going on, and there is no second guessing what the automatic charger is trying to do and and what it is actually doing. The other night I was unable to sleep, and had not realized I left on a bunch of bigger loads, and at 3:30 AM I clicked my battery monitor and saw I was at 11.7v, 63Ah from full, under a 4.7 amp load. I go outside and plug in, then plug in my Meanwell power supply, and knowing I will likely fall asleep soon, I set it to 13.6v rather than 14.7v. When I hooked up the Anderson powerpoles to complete the DC circuit to depleted battery instantly 40 amps was flowing, as there is a big difference between 11.7, and 13.6v. Battery voltage rose instantly to 12.6v but only slowly rose from there, and I went to bed. I am not sure how long it held 40 amps when seeking to hold 13.6v, but I can say for sure it held them for a much shorter timespan compared to if I had set it to 14.7v. How much amperage is required to get this well depleted battery at ~700 deep cycles and approaching 4 years of Age, to 14.7v instantly? Likely 90+ amps. I know that now as is, when depleted to about 40% state of charge it will accept 65 amps for ~25 minutes before voltage at battery terminals reaches 14.7v at which point the amps begin tapering. There is an initial voltage Yoyo when I hook up 65 available amps to a battery this depleted. usually the voltage on this AGM battery will climb to 14.4 fairly quickly at 65 amps, then plateau, then drop to as low as 13.6v, all while sucking up 65 amps. Then some 20 minutes later voltage at battery terminals has risen to 14.7v and at that point the amperage begins to taper. My point is that when one determines the desired voltage, the charging source should be at maximum output in its quest to get the battery to that voltage. Anything Automatic is likely trying to figure out a way to not overcharge the batteries, instead of charge the batteries as fast as possible. The fastest way to recharge is to reach absorption voltage instantly, and depending on the battery(s) and their capacity this can be a huge number, and such high amperage might not be very good for them. When boondocking off the grid, and time to recharge is a big factor, high amps likley means the batteries reach a higher state of charge when one shuts down the generator, and they wil lnot be discharged as much as otherwise that night, and that is likely overall better for the batteries than coddling them with lighter currents. Looks like the WFco only did 60 amps when you had a huge load on the DC system, and it never bothered getting the batteries upto absorption voltage. This is fine when plugged into the grid but not fine for boondocking. Follow BFL13's advice, when boondocking and generator recharging, The powermax adjustable voltage chargers will pump out maximum output until they reach the voltage you have chosen, and then they will hold that voltage as long as you run the generator, and thus basically charge the batteries as fast as safely possible. When at home and plugged in the Wfco is fine and dandy but if using it to generator recharge you are wasting time and gas and shortening the lifespans of the batteries, especially if the next discharge begins when they are no where near fully charged and you do this every day for 2 weeks. When one can spin a voltage dial and watch how many amps flow at that voltage, the mystery of how batteries recharge mostly disappears. I still have an automatic 25 amp charger, but I cannot trust it, and always have to monitor it and second guess it. With the adjustable voltage power supply, the only guessing is how long it will take 40 amps of constant current to achieve absorption voltage, and how long at absorption voltage will be required before amps taper to 0.5% of AGM battery capacity. I beat the Snot out of this AGM battery by discharging it well below 50% regularly, but then I recharge it to full promptly and often. At 700 + deep cycles the time it takes in absorption to reach full charge is much longer than when it was new, and it can accept 65 amps for less time before reaching absorption voltage, and battery voltage falls further when cranking my engine, but overnight discharges, the voltage held under X amount of amps with X amount of AH removed from battery, well the voltage held is still raising my eyebrows as I have never had any set of batteries last this long and do this well even at half the depth of average discharge. And it is all due to recharging fully, promptly. So I Snort in contempt at automatic charging sources, other than my solar controller, whose absorption voltage duration and end amps can be programmed. But hte solar could not keep this battery happy, as there is not enough amps available from my 200 watt array.

RE: Telecom towers and their power

Thanks. My family is OK, but I imagine they are not used to being without power or phone service. I was more wondering about the tellycom towers and if there are standards for how long they have to be able to run when the grid goes down. We talk about telecom batteries on this forum a bit, I was just wondering how long major towers can rely on battery power alone and the same about generators and if anybody here was familiar with the size of their battery banks and how long they can power a cell phone tower.

Telecom towers and their power

I assume cell phone towers have generators, and battery backup for when the generators run out of gas. Does anybody know if there is a standard on how long they have to be able to provide power for? While power was out for my relatives in Florida this morning and Friends in Charleston, SC early afternoon, I got a few texts saying they were safe and wet(SC), now texts are returned unsent, and calls go right to voicemail. I imagine no internet ,no power, No airconditioning, no smartphone data, has a whole bunch of people In SE US contemplating a lot of things always taken for granted, well Those who still have livable structures to reside within.

RE: Power Brick And Plug Standarization

My dell laptop requires a third wire for the Pin inside the barrell, or the battery will not charge, and it runs slowly. When my DC/DC adapter stopped charging due to the third wire again breaking, I was able to splice on a powercord from another Dell power supply my neighbor had laying around. When that Failed in the same manner, I tried to buy just another barrell connector/ wire for a Dell, but it was cheaper to buy an New AC/DC adapter and splice its cord onto my DC to DC adapter. When the third wire on that connector failed, I took my knife to the barrell connector and resoldered the three wires onto it. I repotted the connector with Amazing Goop. I also decided to run the wires to the barrell connector at a 90 degree angle to reduce strain on the connector. https://img2.picload.org/image/rwarogcl/20170805_211420.jpg width=640 Now I need to build that faraday cage for the DC to C adapter, so it stops knocking out channel 8( actual). An AC/DC adapter also knocks out this channel, and uses more wattage at the same time, and the inverter also takesout other TV channels

RE: Eternabond Failure

In applying anything to a surface os something else, it is all about proper prepping of the surface for proper adhesion. But perhaps people prefer to believe marketers lies, combined with price and internet rumor, outweigh logic, and uncommon sense.

RE: Would Mercury Quicksilver grease work in my wheel bearings?

Some greases are not compatible with each other depending on their bases. I used some redline CV-2 on some XRF ball joints, and the grease degelled and started dripping from the zerks. I had to pump in more grease often until they stopped dripping. It is also said that greases with high Moly content are not good for roller bearings as the roller can slide instead of roll. as Moly can plate the surfaces with payers that can slide like a fresh deck of cards. I'd try and find out which grease is in them presently and use somethig with a conmpatible base. Also I did the masking tape grease descriptor thing on my greasegun. The sharpie bled and I'd found the tape had fallen off. I did degrease the area before applying the tape. I;d recommend marking the grease type with a separate tag on a rubber band.

RE: Filling screw holes in roof

3m 5200 is certainly good stuff, but people seem to think it is unable to be removed once applied. This is far from true. I;ve used a lot of it and removed a lot of it. Compared to regular caulk it is more difficult, but by no means impossible, adn in reality not all that difficult. Backing a potted screw out of it, is simple, once one gets access to the screw head. Couple seconds with a wire wheel and a dental pic. I think Naio's best option it the waterproof JB weld. Do your best to mix it properly, ratio wise, and completely and perhaps get a Q tip and some DNalcohol inside the threads.

RE: Filling screw holes in roof

I use Epoxy to repair my polyester surfboards all the time with far better results than if I had used polyester laminating resin to saturate new cloth, and then sanding resin over the laminating resin. I have at least a dozen fairly major epoxy repairs on a polyester laminated surfboard, and it sees actual ocean, actual waves several times a week, as I am a surf bum who will die shortly after I can no longer ride waves. Polyester resins in surfboards are mainly kept as it is cheaper and more production friendly as the rate of cure can be better controlled in a wider range of ambient temperatures by how much catalyst is added. Epoxy usually have one hardener and the ratio cannot be changed to affect cure times. Also a lot of the contnuance of polyester resin use in surfboard building is resistance to change and that many surfboard laminators cannot be bothered to figure out how to laminate with epoxy when they are so attuned to breathing styrene. There is more to laminating with epoxy than spreading it with a squeegee. More finesse is required Time is money, Epoxy is superior in all but heat and UV resistance and price. What I would not do is try and use polyester on an Epoxy surfboard as adhesion could be an issue, and Polyester sometimes will NOT cure atop an Epoxy. Filling a couple screwholes in a fiberglass top, in comparison to repairing a major ding in s surfboard rail, is cakework, but the sun cure / Solarrez surfboard repair kits would be a pretty good solution. Better thn JB weld? well If I had to purchase a product just for this application, I'd buy JB weld. Just get the paint out of the screwholes, and this might require drilling the holes bigger.

RE: Filling screw holes in roof

The commonly available 5 minute or 1 hour epoxies are not really waterproof. I'd say for just a few screw holes use JB weld. Epoxy must be painted over, it is not UV resistant. Sometimes paint does not like to stick to epoxy, sand it and wipe it to remove any blush or shiny spots. I use a lot of 2 part epoxy, of the type for laminating surfboards. To thicken this epoxy I use wood flour, which is basically sanding dust I collect in my belt sander from a 120 grit belt. It turns the epoxy into various shades of brown depending on the wood the dust was colected from. One needs a lot more dust thean they would expect to use until the epoxy is about a peanut butter consistency. There are dozens of thixotropic agents one can add to epoxy to thicken it up, but wood flour/dust is free and more than effective enough for this task. One other possibility is mixing the epoxy, then waiting on it to start thickening, and then once gooey and thicker, mush it into the holes with a straight edge, but this can get messy with stringy epoxy leaving hairs from cup and straight edge. One also needs to saturate the fibers with unthickened epoxy first. If there is paint in the screw holes, I'd want that paint out of there first

RE: Is it ok to put a Maxxair fan here?

That much sunlight getting through the fiberglass means the gelcoat is gone. I'd get some paint on the exterior as sunlight's UV light will deteriorate the fiberglass and the polyester resin used to saturate it. I use rustoleum topside yacht enamel at about 15$ a quart. It is many times better than their regular enamel, but Interlux yacht enamel is 25$ a quart and much better. Get some butyl rope for under the flange of the fan. Do properly prep the roof surface before adhering then screwing fan down. Degrease before painting, paint longevity is all about the prep work https://www.amazon.com/Second-Skin-Damplifier-Butyl-Rope/dp/B0155KELRW

RE: Meanwell PS creates a load?

I just got around to clampmetering my Meanwell rsp-500-15 with it plugged into DC, No AC. I have two Noctua fans attached to DC outputs, so IF I have it hooked to DC, the fans spin. I use 45 amp anderson powerpoles toconnect/ disconnect. I also have a GTpower wattmeter inline, and another brighter easier to read voltmeter which also illuminate when hooked to DC. As far as I can tell, these are the only loads when I am plugged into DC with no AC. The 60mm Noctua nf-a6x25-flx is listed at 0.12 amp draw The 80mm NOctua Noctua NF-R8 is listed at 0.12 amp draw My clampmeter over the wires to these two fans is reading 0.24 amps The wattmeter draws 0.05 amps, not sure of the green voltmeter as its wire cannot be easily clamped, but I will assume it is somewhere between 0.04 and 0.001 amps Total draw according my my clampmeter is 0.33 amps. I know these clampmeters are generally not really accurate down this low, but I have done side by side testing before with other ammeters hooked inline on the circuit and found it fairly close at a single t10 LED at 0.08 amps draw. So as far as I can tell, the only loads when I plug in my meanwell rsp-500-15 to ~12vdcDC are my additional fans, wattmeter and voltmeter.

RE: Rechargeable Lithium Bright Trouble (flood) Lamp?

They have cool white and warm white versions. 89$ Mex, a lamp mounted on one's head is a zillion times better than aiming it in the general direction of where light is needed. Many ways to recharge 18650 batteries, and many headlamps with ridiculous amount of light for under 20$ Borduit on Amazon gets pretty stellar reviews. Get real 18650's though, Panasonic NCR 18650Bs once were top capacity but now are falling into the budget area as there are higher capacity models available.

RE: Sea Foam Home Brew (A Link)

I Know seafoam has an especially loyal following on this forum especially where generators are concerned. But I prefer any fuel system cleaner I employ to use PEA, poly ether amine. Originally developed by chevron for techron, PEA smells fishy and is said to claan carbon deposits without leaving any of its own. Gumout with Regane employs a healthy dose of PEA Redline SL-1 Berryans 3M Techron concentrate CRC GTP, are but a few products available with healthy doses of PEA. Seafoam, well I get enough alcohol in my gasahol that i will not intentionally add even more. I have used the Seafoam deep creep, injecting it into a vaccuum line as I drove for the smoke show and short lived smoother idle and a lazy o2 sensor soon after. BUt I'll stick to the PEA FSC once a year before an oil change. If concerned with carbon in combustion cambers I'll mist the distilled water into the intake trick. Some people use TC-w3 at 2 oz per 10 gallons in their fuel and claim that their piston crowns are spotless.

RE: 100A DC Switchable Surface Mount Circuit Breaker Link

I have a 140 amp circuit breaker on my direct alternator to battery feed. It popped after about 5 minutes of 65 to 90 amps then a few seconds at about 110 amps. I am surprised it popping did not take out my alternator. I also have a 30 amp lever type circuit breaker on my Solar which will max out at 13 amps. The breaker gets warm to the touch, registers warmer by several degrees on my UR temp gun, and drops 0.2v across it IIRC. I bet an IR thermal imaging camera would prevent people from using breakers instead of fuses on circuits where minimum resistance is desirable. I'm never buying any budget wire protection devices again and will be removing those I currently, pun intended, and unwisely, employ.

RE: Does anyone know how many amps an Fantastic Fan pulls?

PWM motor speed controllers should be 21KHZ or higher, to keep them from Audibly Whining ( to humans) at reduced speeds. A PWM motor speed controller should allow infinite speeds upto the max.
