[EU] Custom Li-Ion Battery Packs

Hey folks,

I’m creating this thread because I’ve built a few packs for french riders already and you don’t seem to have many good battery options. Also there aren’t many french people on the global forum (https://forum.esk8.news/ )
Let’s try to keep this thread in english, my french is a bit rusted xD

About me: I’m an electronics engineer based in east Germany and building boards and li-ion battery packs in my spare time.

I use all the good stuff like quality cells from nkon.nl, pure nickel strips (tested in saltwater), insulator rings, fishpaper between parallel cell groups, high temp kapton tape and so on.

Cells I use:

  • 18650: Samsung 30q, 35e, Sony VTC6
  • 21700: Samsung 40t, 50e, Molicell P42A
  • 20700: Sanyo NCR20700B

Nickel I use:

  • 0.15/0.2mm thick, 10, 12, or 25mm wide
  • Pure nickel, 99.96% pure (saltwater tested)
  • double layer, if needed for super high current application
    (or reinforced with copper braid)

Power cables + connectors:

  • 8, 10, or 12awg high temperature silicone wire
  • xt60 or xt90 high current connectors for the output
  • 5.5*2.1mm 10A barrel jack for charging (with rubber dustcover)
  • 10A fused chargeport and fused output (Ouput Fuses: 60/80/100/150)

BMS’s:

  • charge only or discharge bms
  • LTT smart bms with bluetooth if desired (now works with metr module)

Extras I offer:

  • LCD battery meter with percentage and voltage reading
  • chargers suitable to your battery pack
  • double xt60/xt90 connectors for double vescs
  • flexible battery pack

Prices will be fair and individually based on the pack you order. (material costs + working hours)
Since I’m doing this in my spare time, please consider waiting a bit because I need to order parts for packs individually.

Here are some pictures of my battery packs (:

Nice batteries you got there
Even if it’s custom most of the time, could you put the price of the batteries you’ve shown here so we have an idea of your price ?
