400 Ah of batteries in a limited space
I just bought an old ambulance I am converting into an RV. it has a battery compartment for the ambulance module. The compartment is about 19" x 19" square, and about 9 1/2" high. It's wrapped in aluminum, so clearances are important - don't want the battery contacts to hit any of the sides or top, especially when removing/replacing.
I've been trying to figure out how to stuff 400Ah of batteries in there. The high Ah batteries are usually just a tad too high for comfort - really don't want a battery that measures 9 3/8" to the terminals 1/8" away from a nice shiny aluminum plate.
I vaguely remember a flat 400 Ah battery that might fit but I can't find it and I can't remember who makes it.
Any suggestions? Money is of course an issue as well - I can't afford any of the Lithium variants. I'm looking at AGM/Gel batteries.
