Hello all,
Im trying to figure out specs on my battery pack and im running into questions. I'm running a clyte 5304 and a clyte 50ah controller currently set to 60 ah. The bike is a stealth bomber. The original pack was capable of 4500w output
The only thing I have changed is the battery pack which is the following:
72v 35ah pack made of Samsung 50e 21700 cells

Currently on my CA its reading 3800w max output from my upgraded pack.
What im trying to determine is the continuous discharge of the pack. I see the continuous discharge of each cell is 9.8a.
What I need help with is the math to find out what the packs continuous discharge is capable of. Any help would be great! Just trying to get the equation for this but cant seem to find it anywhere. thanks!
 
So would that mean that the math would be
Cell continuous discharge x number of cells in parallel?
9.8 x 7= 68.6?

Thanks

Yes, your math is right. You have 7 parallel groups of 20 cells (in series).

7 parallel, since you have a 35Ah pack, and your cells are rated at 5Ah, so 35/5 = 7 parallel groups.
