Battery building online course?

2 of my fav resources to get you started

Essentially, the core things to a safe esk8 battery are

  • Flexibility. If you have any flex whatsoever, you must connect parallel groups with either copper braided cable or silicone wire.
  • 3 Welds (6 points) or more per cell whereever possible
  • Verified pure nickle only (You can verify it by scratching it up a lot then putting it in vedry salty water for a couple of days. Nickle plated steel rusts/turns the water orange). Sometimes you’re sold fake nickle accidentally even by reputable sellers (That can be lied to or so can their suppliers supplier etc)
  • Never cross a balance wire, and if you have to, use fishpaper to make a little bridge for it to go over
  • Fishpaper everything. As we dont use cell holders in the interest of space, all that stops P groups from shorting is the thin PVC wrap they come in. Use fishpaper as tall as your cell to wrap up the P groups, genuine fishpaper (otherwise called barley paper) isnt expensive.
  • Along similar lines, always use fishpaper rings on the tops of the positive terminals.
  • Never solder directly on the cell, including balance wires. Make tabs for them and solder to the tabs
  • Use genuine polymide (kapton) tape. its cheap as hell and maintains its hold under heat.
