This week I take delivery of my batteries. Rolls 4KS25PS. These are 4 volt, 1350 Ahr. I'll have 12 wired as a 48 volt system. Batteries are 15 3/4" X 10 5/8". 24 3/4" high and weigh 315 lbs. Configuration will be 2x6 (32"X66"
Anyone have a good battery box design? These will sit on a concrete pad (3' X 8" adjacent the end of my 20 ft shipping container and under the 28' X 30' roof that will support the PV's (36 - KC125s). So while basically outside, it will be mostly protected from sun and rain.
I have some thoughts I will put to paper, but roughly plywood sides, front and top. Sides will be slanted 30" in front to 42" rear. "Shed" type top hinged at rear with pvc vent. Front will have 4-6 screws for easy removal. The rear height is to allow room for a removable shelf sufficent to store a few gallons of distilled water and other maintainence items. Painted to match the container.
I'm debating 2 issues:
1. Floor - do I really need a continuous (plywood) floor or is it sufficient to set the batteries on 4 or 5 2Xs with the sides and front attached?
2. Back - do I need a separate plywood back? The 3 sided box would sit againsts the wall of the container. I'm thinking without the wall and plywood floor, I'd have better air circulation, less potential heat buildup.
Any thought, comments, suggestions?
