@Tyson_Davis, your install is pretty slick!
In my GEM truck there is one large battery tray that had more than enough room to hold all 6 of the original group 31 batteries clustered right next to each other with room to spare. The battery tray measures 22.5" wide X 31.75" long with at least 14" of height clearance. The front half of the tray is directly under the seat and extends back under the truck bed.
Either way would work but I decided to go with the split & stacked configuration for the following reasons:
- Save space toward the front of the tray for other electronics that I plan to install where they will be best protected by the seat
- Keep center of gravity low and in the middle lengthwise
- Grant’s video as referenced above
- Split & stacked like firewood, another popular source of stored energy… really this is the modern classic approach
- Should be easy to install because the underside of the truck bed is hollow with an access door on the top as well
- I plan to enclose the battery itself and the attached BMS in some sort of water resistant box. Perhaps something as simple as a plastic bin with a rubber seal will work so I can still show people that nifty battery pack.
This particular bin is 19.70"L x 15.75"W x 11.02"H according to the listing. On Amazon, the Q&A section said interior bottom is 19 x 15. At the top 20.5 x 16 and 10.5 deep. Presumably the split and stacked configuration would be 17" long X 14" wide X 10" high. @Inwo, please verify actual assembled dimensions including “feet”. It may be best to mount the BMS on the original end plate.
This is the long answer to a simple question and @grantwest gave a slightly more concise answer while I was typing this. This is my thought process.
