I am already going to buy a massive pile of 20Ah LiFePO4 (100A continuous, 160A 10sec) for a large 12V battery I am building for a different project (PM me if you are curious). I also plan to get some extra to build an esk8 battery.
I plan to do a 16s1p setup (48-51V, 20Ah, 100A, 2000W). It is pretty much equivalent to a 12s6p or 12s7p setup with Samsung 30Q cells. That is rather large, but at $288 not unreasonable (and same price as for 72xSamsung 30Q @$4). I will also use a balancing 100A BMS (+$80).
This is probably more interesting for people who have a lot of space under their deck or who want to mount a battery block over their truck/board.
I am posting this in case anyone (ideally from Bay Area, CA) wants to join in and share shipping costs. I basically already am getting a special group buy price from the start thanks to my other project - so not a group buy, but even better price.
- LiFePO4 is probably the most reliable and high cycle life chemistry
- Can use standard Battery bars to connect in series
- rectangular alloy encasing for heat dissipation and easy stacking
- good BMS
- needs more volume than 18650 cells
