Alright let’s make use of this new category right away.
No promises this is how you should build a battery but I’m going to document the process as best I can.
The cells:
6.8 Ah * 3.7v * 12 * 7 = 2,113 Watt Hours
So yeah. Range for days.
They’re officially, 30a. It I’m considering them closer to 20a.
Should still be a 140 Amp ampacity so power should be sufficient.
Going to be an upright box or possibly 10x7 with two on p groups laid flat on top. Going to have to nail down an enclosure while I make p groups. This started as a 12s4p so the enclosure I have doesn’t work anymore.
I know I’m really bad at counting, but isn’t that only 9s7p…? I guess 3s7p flat on the top, but how will you pack the BMS and all the wires in there? Is the height of the enclosure even tall enough for 106mm of cell?
Correct. I won’t be using that box. It was just something I had when I still planned a 12s4p. @PrivacyDoctor doctor sold me 36 more so now I gotta find a new box
This should do 12s8p with a stagger, technically its 11.6x8.8 but the zigzag should pick up the needed room. Plus its tall enough to have a vertical layer of cells, then a horizontal layer, then a fat BMS
That space provides 301.6x228.6mm, a staggered 12s8p 26x80 cell pack will be 273.7x221mm so you would definitely be in clear
The battery i had built was a 12s5p double stack under a trampa HS11 had to custom make the enclosure out of pretty big plastic tubs. A double stack with these takes up the same space as an 18650 triple stack. These will only work for top mounts or very big decks that have lots of space underneath
A Trampa Carver DS can almost fit a staggered DS 21700 so pretty sure I can fit a single stack 12s if you’re creative AND that’s exactly what I’m gonna do now for my Trampa Carver. Who wants some P42A cells?
but a really great performing cell! I would consistently get 30 miles with end of ride voltage at above 44v on 12s
