Between that and the dozens of reviews of this unit, it does not seem to be a danger to the battery, it just might not charge it properly.
Maybe PM me what you have. I'd like to get a close look at it. I also have a friend that can decipher a bit better of the BS no matter what language.. LOL
Test it out and let me know, please 14.2 at a charge value is good if it rests (yes all batteries rest) at 13.4 (preferred 13.6) it's good, again as I understand it.. My current 60ah battery (LiPo4) rests at 13.3 and runs the DC Frig 3 days (2.5 on really hot).. Not all run like we hope, yet I go amp in to amp out, I'm good with my little 60ah.
Well I say that and I'm building up 100ah system to integrate.
Oh ya, we play with ideas!
Love seeing what you're doing!

No problem. I have not tested mine, but on paper it looks right. Test yours soon so if it is non functional with your Lifepo4 you can return it. I am over the return period I am sure.
What size panels are you using? I went with 300w just becuse it was the biggest I could afford that would fit space wise. I mean I could fork over for a 1200w kit but need WAY more battery, and they would be rigid panels that need a LOT more roof than my camper shell provides etc...
I also need to find a compact 110v charger for the lifepo4 so I can charge off of my generator if I end up needing to...
Honestly, if you say you can run your DC fridge for 3+ days on a 60 amp hour battery, I don't see why my power needs aren't met for 3 days between drives or charges with my 200 amp hour battery...

Take a look at how thick the insulation is when you cut the jumper cable, the Chinese ones are notorious for having super thick insulation and skinny wire. Jumper cables aren't like your father's jumper cable anymore.![]()

You are probably right.
Probably best off just going to Lowes, or Home Depot and getting some 4ga by the foot...

Or to the next swap meet!

Never seen bulk wire, particularly large diameter wire, for sale at the swap meet. I have seen all kinds of crazy stuff at the Swap Meet, just not wire like that.
I stumbled across a price drop, It's not a suitcase, but I came across a 600w solar panel, wire, and charge controller kit for just over $300.00 on Amazon today. I already have the 300w suitcase though, awfully tempting to double the charging. Honestly when I do end up building the foamie, I want to stuff 1200w on it, and enough battery to not worry about running a 5K BTU AC 24x7 if I have to.

You buy that solar panel and you'll have more on your camper than I do on my garage!! LOL
