I'm building a custom electric motorcycle and looking for guidance on the battery pack construction. Here's what I have so far:
I don't need much range as this will be more of a show piece, but I would like it to have decent acceleration and freeway-capable speed.
What I'm wondering is:
If this isn't sufficient, I do have space in the bike to do another battery pack. To simplify, I would build two identical packs (two 14x8x2 packs). I'd rather stick with one (cost, simplicity, weight, effort, etc.), but if my setup needs it I will go with two. Would it then be better to build each pack 14s16p and wire them in series to make a 28s16p battery?
I have a ton of experience with ICE bikes, but this is my first EV project, so any advice is appreciated!
- Motor (already have this):
Motenergy ME1507 (600A peak, 157A cont)
- Battery (planning to buy):
Molicel P42A 21700 cells 4200mAh 45A
28s8p (224 cells), approx 100V nominal, 360A discharge, 3.39 kWh
Layout is 14 wide by 8 long by 2 tall (cells are vertical)
I don't need much range as this will be more of a show piece, but I would like it to have decent acceleration and freeway-capable speed.
What I'm wondering is:
- Can I trust the Molicel discharge number?
- Is 360 amps enough, or do I need more to cover the motor's peak amps?
