RE: Battery monitor: useful tool or toy?

I did a little playing tonight with that elite.element combo meter. It seems like it can be a poor man's Trimetric. From what I can tell, you can set the battery AH capacity, or any reference number you want as a substitute. Like say 50% of your AH capacity. And you can tell it how full you are now for AH in percentage terms. From that point on it will track net AH in and out, and tell you where you are in AH storage and percentage. No Peukert compensation though. At some point you'd have to guesstimate and reset your numbers. Unfortunately it appears it loses those settings if you disconnect it from power. But, you can leave it connected and blank the display with one press of a button. I will install it on the battery side of the disconnect switch, and will have an on-off switch so I can turn it off if need be. The shunt is only 100A, so no good for those with bigger inverters. Maybe not even enough for a genset starting? Not sure. I think they sell a 200A version too. Anyway, it's another ebay-China hobby project type of thing. If it works half- decent it should be useful to me.

RE: Battery monitor: useful tool or toy?

On a budget, a person could try something like this. $36 on ebay. For some reason this listing is priced in Aussie dolllars on the US ebay site. The one priced in USD is a few bucks more. I bought from this listing. Just got it today, so I can't tell you how good it is. But people on the internet have liked it for various charging applications. It has a 100A shunt. http://www.ebay.com/itm/181137155880?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

RE: 12V LED TV options

I just bought a Samsung 24" class 1080p TV last week. 20 to 21 watts, measured on the Kil-A-Watt, great picture, through a small 175w power inverter 12v to 120v. Then through the brick back to 14v. Picked it up at Costco for $169, had a $30 rebate, don't remember when the rebate ends. Great TV, very very happy with the picture. But will it work off of 12V is the real question? We all know it will work off of 110/120v Yes, it will. I have a Samsung in my current RV. Running it direct off 12V. If you want to make your own 12v cable without cutting up the OEM cord, you might need a Philmore 265 plug for the TV end. You can google it. Not too many sources, but there are some. Also available as Enercell "T" plug from Radio Shack. http://www.radioshack.com/enercell-adaptaplug-t/2730322.html

RE: Class A vs Class C: Maintenance and Towing

For starting out, the truck and trailer are probably the way to go. You might find your Xterra could pull a decent smaller TT. I really don't know. But keep in mind, a trailer is much roomier than a Class C for a given length, due to the cab on the C. Slideouts can affect that, of course, but I'm just saying that a 22' TT can be roomier than a mid-sized C.

RE: 12V LED TV options

We had a Vizio that was sold with our previous RV. It had the brick, labeled 14v. It ran perfectly at 12.0v. Others have reported the same. It was a 22 incher and consumed something like 21 watts.

RE: Have you replaced the awning of your Class C?

I did mine once. It's intimidating, and I did lose control of the spring at one point but with no injury. Not sure I'd do it again. Maybe. The problem I had at the time was finding good instructions online. Maybe youtube has something now.

RE: Renting A Car

We do not toad to Arizona. We take advantage of Enterprise $9.99 a day on weekends. They pick us up Friday AM and drop us off on Monday after we turn in the car. Only 100 miles per day but that is plenty for us. With tax were we are it equals $32.04. Wow, that is a good deal. Is there any trick to getting the deal? We will be out in PHX and Tucson for several weeks, without a toad.

RE: 3500W Inverter Generator for $699

Look forward to hearing about it.

RE: Measuring V loss during charging

Leave a light on tonight and let the battery run down a bit. I had it set up with 6AH draw going, planned for 16 hours. But I just stopped it. Tomorrow is supposed to be wintry and 30+ MPH winds. :( So my plan to have the converter sitting under the MH, possibly exposed to driven rain/snow, was not looking good. I'll do it in the next 2 or 3 days.

RE: Measuring V loss during charging

Next test, sometime tomorrow: Same WFCO converter, but wired direct with only 3' of cable each way (just outside of the battery compartment). Ideal conditions, in other words. Temporary placement, not installed.

RE: Measuring V loss during charging

Yes, I recently started the thread about the Mean Well, as something to supplement my converter when using the genset. This thread was mostly my attempt to learn about how to measure voltage loss. And I was surprised how bad my OEM setup is. What I'm trying to say is that my intent with this thread was not to be looking for charging advice. Not that I mind getting it, but that was not my goal. I did take hydrometer readings the other day though....

RE: Measuring V loss during charging

Thank you. Basically, my so called 55 amp converter charger, with this wiring, is more like a 5 amp charger. This morning after 20 hours of charging, the battery voltage matched the converter voltage of 13.66, and there was about 1 amp of current. 20 hours is no problem if you are on shore power. Unfortunately the batteries will sulfate over time due to never seeing 14.4v or more. But hey, camping on shore power, who cares about the batteries, right? :) And you haven't put enough thought into the issue. If you're charging the battery with the gen then you want fast as possible charge to 80%. There are two requirements for a fast charge. They are equally important. 1. A converter that can output at least 14.6V in boost. 2. Cable resistance of 10 mohm or less. I reduced my charge time (to 80%) by more than 3x when replacing the Parallax converter with a Iota and reducing the wiring from 25 mohm to 10 mohm. You are way over thinking the issue.

RE: Measuring V loss during charging

Hi Don, Are you thinking of a gentler setting, or a more aggressive setting, for the flooded batteries?

RE: Generator Starts Up On It's Own

I had the same thing happen on our 2014 Sunseeker with Onan 4000. The dealer said it was a bad switch for the genset. I have not driven it enough since the repair to say for sure that he got it right. It's hard to see how the radio problem ties in, though.

RE: PowerTek tv lock out

You say the 12v outlet works off the house batteries? If so, remove the house 12v fuses one at a time till you find the one that controls the outlet. If you don't find one, that will be a clue. If you do find it, that will be a clue too. Bottom line, I suspect there is another relay. Maybe at the chassis fuse box, as LittleBill said. I'm just guessing as to the where.

RE: Measuring V loss during charging

Am I missing something? You're not seeing too much of a drop...just 2%. At how many amps? 2% at 10 amps becomes 8% at 40 amps, for example.

RE: Measuring V loss during charging

Add switches to my list of things that constitute "wiring".:B I just checked and found that the "converter circuit breaker" (located inside the house-chassis batteries interconnect relay control system) is responsible for a big voltage loss. Almost as much as all the other "wiring" combined. It can easily be bypassed when I re-do the mess. I'll have to find a fuse or CB that is better.

RE: Measuring V loss during charging

Pretty soon somebody will mention Watts and ruin everything! :( Haha! Well, it's good enough for government work. I proved to myself it's a problem.

RE: Measuring V loss during charging

For those who might be interested in the wiring being studied. I can mount the converter very close to the batteries. This will be done. SB in my drawing means "should be". https://lh4.googleusercontent.com/-k-3y5xhrsFA/Uz2L328jQmI/AAAAAAAABsM/Ta8HEmjk_Pg/s512/2300BattWiring.jpg width=480

RE: Measuring V loss during charging

A while ago, at 9 amps, the converter was 13.62 and battery was 13.34. Or was it 13.43. damm I shoulda written that down. Again E=I*R I=9 R=0.036 So E= .324 13.62 - .324 = 13.3 You memory is good at 13.34 The small difference is due to rounding, instrumentation variance and general conditions. Ohm's Law itself is exactly precise. Next one 13.64 -13.47 = 0.17v, 5.8A Using the above, should be 0.21v So, pretty close again. It's a clamp ammeter so there is some error there. I guess that paints the picture then. Man that is a lot of drop at higher amps. I'll find my sketch of the circuit and post it for snicks.
