You will love your Battleborn batteries. And maybe not for the reason you think. The time to charge is significantly less. Given that many National Parks only allow 4 hours per day of generator use, it would be virtually impossible to keep the 4 6v batteries at 100% with only 4 hours of generator time. And that was with an RV fridge. The charge profile and charge rate (with the proper Charger) is a game changer for Boondockers with or without solar. Best of luck.

Was this a lithium battery?
If so this is a smoking deal.

I have 470Ahrs of Deka GC2 lead acids. I have no problem getting them back to 90% from a 200Ahr deficit in 3 to 4 hrs. I do have 120amps of charging available though. That last 5 or 10% is the killer and honestly, I don't worry about it unless I'm more than 4 or 5 days without a top charge.


I get what your saying though with the Lithiums charging faster. It is the absolute main reason I will go with them next. I think they are even more advantageous for campers like me who rely mostly on a generator to recharge. We're in the east and almost always in the trees.

But, the unfortunate thing is you need to be at your camper to run the generator instead of out seeing sights, regardless. We have a BIM in addition to generators and solar.

Breakfast time and late evening dinner/shower time is generator time for us. Before and after the days activities.

Solar is of little importance to us at this time. I do have a 40 amp DC to DC charger.

When not in use can you leave lithium batteries on charge from your inverter all the time?
I always leave my camper plugged in because I use it all the time, to take a nap, for my garden supplies and any thing I might need it for.

We leave ours plugged in all the time. Our inverter/charger is built to not harm batteries when left on shore power.

Recently saw a program where a lithium "expert" stated that all cables between the batteries, and the two cables to the controller, had to be equal length to minimize any imbalance in the charge/discharge rate, otherwise the battery connected with the least resistance would be overworked. I don't know, and I have no opinion on the validity of this, other than it seems logical.

Not really.

This is the best write up I've found.
