So, I got four Valence U1-12RT U-Charge Lithium Batteries that I got cheap.
12.8V, 40 Ah, 512 Wh. Max Input 14.6V. I have a PowerMax 1000W Pure Sine Inverter. I made some 1 ft long 6 AWG cables. I had planned to mount the Batteries under the bed, and hang the Inverter on the cabinet wall next to them. The batteries are 5" x8".
I'm wondering what's the best way to place the batteries to get as many as possible to hook up with 1 ft cables in a 'star' configuration with each set of cables going from each battery to the inverter, or to some disconnect/ breaker/ etc.. Should I put them long side or short side toward the inverter? Some other arrangement? I'll probably sooner or later get more batteries. I have some heavier cables and a buss bar if I need it. I wonder if I can bolt the Buss bars
down alongside the batteries on each side and strap them down from there...
I planned on bolting a piece of 3/4" plywood, say 18" x 18" to the floor, and then strapping the batteries down to the plywood. Does Harbor Freight of some other place have good material for strapping the batteries down?
I'm kind of winging this initial setup. I imagine I'll modify it or upgrade it soon, but I'd like to have something for a holiday trip.
