[US] WTB Li-ion battery cells and pack building materials

Looking for materials to build a couple packs, and thought I would post here before buying it all new. Plan is one 13s5p (48V 25Ah) using Samsung 50G cells, another using 18650’s (13s5p). Max current 25A so I don’t need the crazy high discharge from moli p42 or p45; I prefer higher capacity 5000mAh cells (21700) and 3400mAh+ (18650). 21700 pack is higher priority for me. Needed items include:

  • 21700 cells (5000mAh+, qty x65) current candidate is samsung 50G’s from ebay (X20 Samsung 21700 cells 5Ah (5000mAh) INR21700-50G - New (Li-ion). Comp. w/ 50E | eBay)
  • 18650 cells (3400mAh+, qty x65)
  • Positive terminal insulation rings
  • Cell heat shrink wrapper
  • Wide kapton tape (50-70mm width)
  • Wide fish paper (50-70mm width)
  • Wide fiberglass tape (50-70mm width)
  • recommended glue for securing balance wires (low temp hot glue?)
  • spot welder, in a separate post
  • spare 10 or 12 gauge red+black wire

Happy to take any extra or used parts off anyone’s hands. Shipping to California USA.
