15S1P configuration.

[DPower]

Just wanted opinions on doing a 15S1P pack of 21700 40T cells. Id like to lay them out in a single, long stack to minimize the height of the pack. I will be using 10mm x .15 nickel and wondering if I should double the strips on each serial connection or not? The constant current will be 10-15amps. It will be using a smart BMS as well. Thanks for any input!

Is this a skateboard or some other space constraints that limits the P-group to 1?

Yes its for a skateboard. Thats why its limited.

double it, 1 strip of nickel is 10 amp max, I don't know if you can solder copper to the strip before spot welding the nickel strip.
ive soldered copper to to the nickel that was already spotwelded on my pack to get rid of the volt sag /resistance
