I am using 1-1/4 by 1-1/4 plated 18 gauge "L" channel steel to build a structure to hold the batteries in
the previous engine compartment. I am using a piece of 1"x1" square steel as the anchor point between
the new motor area (see big round thing = motor mockup) and the rear of the battery frame.
Erector set style, I connect the pieces up. The original subframe has a cross piece that I try to leverage to hold a battery. Note I needed to create a system of little "L" brackets to keep the batteries from sloshing around.
The batteries are UB12550, about 40 lbs each. I plan to use 5 for 60 volts, each is rated at 55 Amp-hour capacity. I will mount them sideways, terminals starboard side to
be wired up. I am starting with 2 actual batteries for fitment and until I get everything running.
One thing I learned quickly is that the batteries are not exactly square. They widen to towards the top, tapering below. Also, the terminal location interferes with my use of the "L" channel - notice how parts had to be cut out to make space for the terminals.
To create more structure to connect the subframe to the top, I put some L channel across the wide
top of the frame. Here is a view from the seat area.
Note in this picture the addition of extra cross-bracing, using 2"x12 gauge plated steel. This is strong,
heavy stuff, used by "El Ninja"'s creator. I used a big piece UNDER the subframe to reinforce the battery rack under the 80 lbs load directly above.
Big unknowns/risks are trying to actually run wires to the terminals, and getting tie downs in place to
hold the batteries down.
