Could you guys please double check my thought process before I mess something up.
I want to build a 12S2P Lipo pack using 4 Turnigy 6s 500mAh 40C Lipos with a Bestech D140 BMS using 10awg cables for delivery. Does anyone see an issue with that?
Here are my specs.
MBS ATOM mountain board
203mm inflatable wheels with - 84 tooth pully
Dual 6374 BKB 190KV 3200watt max 70amp motors -10 tooth pully
FOCBOX Unity on preorder
15mm wide belts
My thought was once I wire these 2 parrall and 2 series to get 12S2P would give me 10000mAh so at 40C would be 400 continuous amp draw?( I know the C rating is overstated) but is my math correct? wouldn’t I still have more then enough?
You mean 5000 mAh batteries to start I think was 500 in original post but assuming 5Ah battery in parallel with another then the math sounds good to me.
Like gummy said mfg ratings for this kind of thing are generally inflated though and not to be trusted if you want things to last for a good amount of time/cycles. Good to see third party reviews and discharge charts to compare cells.
By experience I say that 14T is the minimum if you want your belts to last, 12T the radius is too small and bends the belt too much, at that size my belts lasted 100km tops, with 14T I never broke a belt so far
