So I’m about to buy my samsung 30qs and I’m worried that perhaps I may get some duds.
I’m planning on doing a 10s4p so I need 40 cells for it to work, but should I order a few extra? I’m planning on ordering from liionwholesale.com and want to order these but I feel nervous about just ordering exactly 40 just in case!
So when you all build your batteries, do you order extras? If so, how many?
