Battery Building Shopping List Thread

Battery building items only lets go! (I’m a noob but couldn’t find a specific topic for this aside from eboosted eskate building thread so let’s see what you recommend for battery assembly)

Lemme just add to this, I personally guarantee DBS’s excellent shipping speeds and customer service. I had my first purchase lost in mail and Mr Benjamin ate the cost of the parts himself and sent me everything he still had in stock, gave me a coupon code for everything else. Component quality are excellent as well. Made 3 purchases from him already, very pleased.

Don’t forget

  • Fishpaper
  • Hot glue gun and/or hotglue
  • Kapton tape
  • Multiple sizes of heat shrink for wires and plugs
  • Soldering iron
  • Good quality solder (60/30 is pretty much the best bet WITH lead)
  • Flux (optional if you get leaded solder)
  • Wires 14,12,10 AWG
  • Multimeter (cheap expensive doesn’t really matter as long it’s precise ish, 3.221V is better than 3.22V)
  • Charger (1S for balancing and the big charger for the finished pack
  • BMS
  • charge plug (different than xt90, you don’t want a big fire lol)

Thats pretty much all I can think of, AKA all or almost all I was missing with my first build LMAO. I’ll try to add links later when on PC

It’s for an ebike right? With the model 3 batteries ? Might have mixed up some people lmao if so you might want to also get some copper plating 0.3 to 0.6 should be sufficient for the amps you’ll continuously pull but will have to solder it as it’s a pain in the butt to spot weld copper

Anyways good luck with all those and your future pack :smirk: :smiley:

if your a noob I recommend buying a multipack of BMSs , I think I killed 3 on my 1st battery build, I’ve killed about 8 now - few years on I still always buy 2 when I need 1 and I’m still scared to touch my DieByeBMS as I don’t think it would survive me… recently tried making a 13s smart bms a 12s and blow it up lol

I’d be scared to ride the boards with your batteries in them​:joy::joy: did 3 packs and the BMS’s all survived so far but it’s a good advice to get more just in case
