First Pre-Built Board Decision Help

There have to be a lot of used, burnt boards around. They couldnt cost too much.

I figured out the dimensions of the battery I need to make, and that I’m going to use p24a or p26a cells. But now its a matter of getting more parallels than series and actually making the battery but idk if i can do either of those things.

THAT doesnt sound like you understand the formula. You KNOW ?S?P right?

Oh yes I’m aware. I mean I’ll probably use p26a batteries. But as for the actual pack it will be, or at least what I’m at least trying to do 10s3p
