@shade, well yeah.. but at least its not trying to overload it for 5-6h.. only a couple :p (hint: you really should have a DC charger for a LFP, dont trust your alternator not to cook everything.) @67cj5, yes thats pretty much it.. you hook it up to a 10A charger it'll take 10A til its full...

https://battlebornbatteries.com/comparison-one-battle-born-lifepo4-battery-two-6v-gc2-batteries-series/ TLDR: 11.8V to 14.4V @ 40A Charger, same charger/settings used on both. LFP: 2.5h FLA: 5h Thats just at 0.4C charge rate, technically the BB will take up to 1C charge rate (100A) but they...

If you have solar your golden, that will gladly get the battery back to full.. despite any voltage drop on the standard trailer harness.. Sounds like your not running a DC fridge or anything, you'll be fine, dont over complicate it. When you get back home after an outing, let the solar put the...

your not really going to get much of a charge, little more than a trickle all the way back there.. but just go hot back to the battery, nice and simple.. your trailer battery also needs to be able to provide braking power in a break away situation. A charge controller would really only be...

Check out space trailers, my old Golf pulled one around the equivalent of the diameter of the planet, twice.. without fault.

yeah its got built in gps

or just slap a cheap ass digital thermometer into your battery box for a few weeks now in the heat of the summer and then pull it out and check its max temp readings.. some double sided tape or something so its not making contact w/terminals. this i think would be more accurate because the...

Yeah the bigger ones will end up the same way after you put some miles on em.. the mass market builds really are garbage builds, they hardly stay together for people who use em once or twice every few years.. I hadda live full time out of a mass market camper once (tornado took our house out)...

Yep, I too found that I didnt need as much AH on LFP as I did on Lead.. its a combination of factors and not just Oh well you can discharge it 30% more that are quite substantial when all added together. Yes, you can discharge it deeper w/out abuse.. however they also: Take less capacity for...

Exactly, if you had a balloon/radiosonde recovery vehicle or something I could see a mobile igate for taking a non 144.390 tracker and putting it on the APRS-IS network.. but then you really shouldn't have your igate advertising that capability over 144.390 since its not listening to it.

I setup a mobile iGate because my tow vehicle has built in hotspot, then had some deep discussions elmers and the general consensus is that Mobile iGates are bad for the network.. kinda like a mobile W2 digi.. TX igate requires that you heard someone nearby before you TX, and then you've done...

yeah basically, use fiberglass to repair any cracks/gash.. sand it down, power wash it, and re-gel coat the whole thing, it'll look brand new.. the UV and weather basically wears it down over time.. all those nice pristine Westfallia's at the car shows, just took the top off, re-coated it, put...

while your at it.. pickup some white gel coat too, you can make that westy poptop look brand new as well.. or make em both white.

Yeah true, if you wire a diode up to that feed branch coming off main circuit breaker it'd stop any back feed into the rest of the system.. If you want to get real fancy you can hide a momentary switch under the dash that powers the solenoid from the aux/house battery and have a push-button jump...

Technically LFP batteries w/BMS are easier to charge than others.. you just need one stage, can be dumb as a box of rocks as long as you can set the constant voltage output.. the trick is, you disconnect the charger entirely when its full or put the float voltage low enough its not actually...

Nonsense, first of all no batteries "like" heavy discharge rates.. My LFP battery will run your compressor I'm certain, and it runs my microwave no problems.. shame you didnt do your research and buy one that could handle it.. (your max is 100A, my max is 200A, I can handle the startup surge of...

ding ding ding, its completely safe to pull load out of a LFP below freezing.. and it dont have to be much of a load and it'll warm the battery up on its own. for example, I set my BMV high temp alarm @ 120F.. if I run my Microwave for about 5mins it'll jump from ambient to 120F before the...

Low voltage? everything is ~12v.. w/a relay setup, you just need to wire it up to a keyed ignition source.. same as your radio and other accessories, so when you take key out.. the relay disconnects everything.. its self jump starting because it'll combine the batteries right before you fire up...

oh ******** yeah, now thats worthy of building a board for.. thanks for that, now I got another project to work on.. when I uh did some mods to the main unit I'm sure there was enough room in there for one too.. then at least when I wanna chrip in a bunch of new repeaters before a trip I dont have...

naw dawg.. in simple terms.. Best Bang for the buck FLA, cheap as you can get.. use em, abuse em, throw em away and get new ones several times for the cost of anything else.. 6v GC Batteries carrying the most lead for the least cost. Worst Bang for the buck AGM/SLA.. literally nothing but...
