Re: Sourcing a LOT of custom 18650 battery packs with BMS

Im planning to start a custom battery company based in Croatia, just for jobs like this one.
If you could give me some specs, I could maybe give you an offer :)
The cells would be sourced from nkon or other reliable supplier and you could drop by to do QC anytime :)

Re: kWeld - "Next level" DIY battery spot welder

I did that to both green and red graphenes, and the problem is the same, usually only one out of 6 gets unsticked, but that is probably from the heat, I once put my finger on the terminal and did a weld and it got hot for a really short time If you have disassembled one of the red ones on your desk...

Re: kWeld - "Next level" DIY battery spot welder

but the solder unsticks probably from heat and then ... if this happens you see any problems on the welders site? crazy setup for a tool doing side business. Yes the welder turns off, and sometimes I get a low voltage error when (when there the wire is barely making a connection to the terminal )
