    Value of Heated Batteries

    Yes, I get that. A heated battery in that case will keep from charging a too-cold battery because the heat is provided by the charge current. But my worry is if you’re camping and it’s well below freezing that the low temp cutoff would trigger on the discharge side. And that doesn’t seem to be...

    Value of Heated Batteries

    I guess I thought that the charge and discharge temps were the same. Thanks. That got me to look at the SOK site and they say both charging and discharging to -4F. Seems like there’s not a lot of value even to the heated battery either. As you suggested, he’s not interested in camping in...

    Value of Heated Batteries

    This is not really a lithium DIY question, but I’m looking at putting together a heater and thermocouple for a lithium battery so it’s kinda DIY. Anyway, I’m looking at the SOK 100ah battery for a friend who wants to cold weather boondock camp. My understanding of the SOK is that it draws the...

    Sizing a Circuit Breaker

    I used the 400w blueprint on Will’s site for my own camper (I'm having a hard time inserting links without them all going to the beginning of my post). Based on this, I'm basically following it on my friend's camper. However, he has a smaller camper, a Lance truck camper, and the space fits 2...

    50ah 12v LiFePO4 Batteries

    I've mentioned in another thread that I'm helping a friend set up a Lance camper for a long term trip. For a number of reasons, we'd like to go with Lithium batteries. One of the things he'd like to do is run a microwave off of an inverter. The catch is that it seems like most 100ah batteries...

    Inverter in RV Electrical System

    Sorry, but could you explain that further?

    Inverter in RV Electrical System

    I've put a 400w solar system on my Class C RV broadly following the Will's blueprint for that setup. I have a small inverter that powers "external" devices. I'm also helping a friend put solar on his Lance slide-in truck camper. In both cases, we want to be able to use the microwave off of...

    Heating pads under battery

    Is there a resource here that explains how to diy that? Or could you?

    Heating pads under battery

    So you are saying that on a cold night, you just turn on the heat and leave it on?

    Buying Used Panels

    Ok, but how do I check for function? I bought myself new panels because I was in a time crunch and couldn’t spend the time learning. But here I’m looking at minimum spend. Is it just lay it in the sun and look for volts and amps at some percentage of rated? Is there a ratio of each? How do I...

    Buying Used Panels

    Yeah that would be nice, but he doesn’t have that info. I asked him what voltage he had and he didn’t know. I asked if he had a controller and his reply was “the little box? Yes.” He inherited the place from his grandfather who pieced it together over years, I’m guessing. It probably looked a...

    Buying Used Panels

    I took my camper with my new 400 watt solar system on the road for the last week. It worked great and I’m mostly pleased (an issue for another day). However, I found out that the guy who owns the property where I surf in very rural Mexico was robbed of his solar panels and other things. He...

    Older converter compatibility with SOK Lithium 206ah battery

    I had a similar question and response from SOK. In my case, their take on upgrading my charger was “why bother?”

    Dead SOK LiFePo4 Battery

    The trickle charger got confused so I put the transformer on it while I went and got my multimeter. Looks like it did the trick. Thanks. And by the way, I opened it up and saw no obvious fuses. Just FYI
