I have a 10s4p build with those cells: https://eu.nkon.nl/rechargeable/18650-size/lg-18650he2-imr-battery.html But i have now ordered a spotwelder to make a new 10s4p pack with the same cells. I don’t know in what time you want to build you’re board. But when making my own pack go good. I want to make also packs for the esk8 community.
PS: I am from Belgium
