RE: LIthium battery upgrade - Complete!

oops--sorry. I thought they were li.

RE: Can I hook up to a house from a 30A plug to a 15A circuit

Hi, It is best to add up all the items and keep the wattage below 1440 on a single 15 amp circuit. I can't imagine the loads you want to run being more than about 800 watts. That would include 325 watts for the fridge. 30 amps should trip the breaker. It would be easy to test that by deliberately turning on items. So, being that the RV has a 30A system, when plugging into a 120V 15A circuit, is it going to draw all full 30A? And will it cause that particular circuit to become hot and cause a fire? The literal only things being used in the RV 1 overhead light in the bedroom, a computer monitor and deskot computer.

RE: Splicing 30A plug to 50 amp cord

The cameco male seems to work ok. I don't understand why the females are so very different. This did not happen to me just once, but rather 3 times.

RE: Splicing 30A plug to 50 amp cord

Do not get the cameco female. Their 30 amp will burn up with a 15 amp shore power supply. I got progressive 2nd time round--not a hint of burn up. BTW the most frequent cause of burn up is low voltage. I'm using an autoformer now and love it. Sola Basic 4000 watt. They make an 8000 watt unit too!

RE: LIthium battery upgrade - Complete!

Hi 2old, Thanks for the depth of charge tidbit. I see that costco is selling double A and triple A LI cells now. The price was competitive with other small batteries. They are calling them Eneloop. They are claiming 2100 cycles.

RE: Can I hook up to a house from a 30A plug to a 15A circuit

GFCI is not a surge device. It won't trip from an overload, only from a ground fault. 15 amps should not be run at more than 12 amps continuously. Translating that to watts means you can use any combination of devices that total up to 1440 watts. I run oil filled type heaters that have switches so I can reduce the load. It is best to measure each device with a kill-a-watt meter. I carry #12 cords for running from residential outlets.

RE: 48 inch wide rolls of Eternabond tape?

I ordered some 48" wide to repair a roof on my home. It is special order.

RE: ARP Refrigerator Protection

Gjac, These were the only times that the unit shut down the fridge. I was not "out of level" any more than usual. It was not cold enough for my Thermocube controlled light bulb to come on.

RE: Edison Batteries

Hi, Thanks for trying to research this chemistry. The problem is that Nickle has always been expensive, compared to lead, so even if Edison cells are "better" they are not, in the short term, cheaper. I'm reminded of our qwerty keyboards that are no longer necessary. Yet very few folks make the switch to dvorak, which would boost average typing speeds by 20%. I did a search for an hour or so trying to get good performance data on these "Edison" variants and (snip) My gut tells me that as well researched as the technology is being well over 100 years old, the batteries would be widely used by now if the reality could live up to the hype.

RE: Edison Batteries

Hi Phil, Yup I got it wrong (again). Mind you 1000 cells would be pretty amazing to have LOL-but then weight WOULD be an issue.

RE: Surge Protector?

Why? Because the cheapo doesn't protect you from much. Because the cheapo doesn't look for reversed polarity, or open ground, or bad neutral. Because the cheapo doesn't disconnect on low voltage (imo 104 is too low, but that's another story). Three strikes and the cheapo is *out*. As I said earlier, I prefer an autoformer, since the "silent" damage is more often from low voltage. you want a multi-function surge protector. $250 and up. not the $90 special. bumpy Why?

Hi Eric, Please keep us updated on how they behave.

RE: ARP Refrigerator Protection

Hi, I have it installed in my Fridge. It has been great for my peace of mind. It has gone into protection mode 3 times since installation. All the times were in cold weather.

RE: Edison Batteries

Hi Phil, Their other advantage is zero plate deterioration, so after 30 years, change out the electrolyte and start over! The 112.5 amp-hour is 3.2 inches x 5.6 inches x 14.5 inches, weight 14 lbs. (times ten cells). So for 112.5 amp hours @ 12 volts. 32 inches x 56 inches x 145 inches. A huge space issue. When I first read it--I thought each cell was 140 lbs.

RE: Surge Protector?

Hi HarmsWay, I use a Sola Basic which offers three levels of boost (at 110, 100, and 90 volts) and one level of buck (135 volts). I use an add on surge device which offers much more protection than the PD, SG, or Hughes. I do manually check voltage under load, and polarity before I plug in the RV. If that shows lots of voltage drop I add the Sola to the power path. I do lock it down enough to prevent casual theft, but in these days of battery powered cut off wheels it would not stop a determined thief. The Sola units are sold in Mexico, so to get one you need to have a friend who will purchase and transport it for you (or make a Mexico trip). http://www.isbmex.com/productos/corrector-de-voltaje-8-y-4-kva The Hughes offers the same level of surge protect as the PD. I don't know if the SG unit is more capable, but I doubt it. Do you use one of those units? They seem quite large so I assume you keep it outside. Any issues wrt theft or weather?

RE: Surge Protector?

Low voltage causes more damage that surges. I prefer to fix that by using an autoformer. BTW anyone who wants to prevent brown outs should consider the new Hughes autoformer which does test polarity, bad neutral, bad ground, has limited surge capability, and of course corrects low voltage. https://hughesautoformers.com/wp-content/uploads/2015/06/led-display-home-trans1.png width=400 http://hughesautoformers.com/

RE: House batteries off gassing with Tripp Lite

Hi, Sounds like a shorted cell. Do disconnect the batteries asap.

Have you measured the charging voltage?

RE: AT&T Unlimited Price Increase

Hi, My t-mobile is 3G and I find it works well. It throttles at 28 gigs of hot spot now and is unlimited 2G after that. On the device itself the connection is LTE which I understand is 4G?
