    Sourcing a LOT of custom 18650 battery packs with BMS

    kWeld - "Next level" DIY battery spot welder

    Actually the lipos can give enough current but the terminals are the problem so Im going to make a 2p pack out of 4ah red graphenes

    I think I already measured either green or the red one and sent the measurements to your email, the terminals have some solder on them so i can not give you the exact thickness of the terminal, but its too thin to be able to carry those currents reliably anyways imo..

    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

    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 )

    This is what i have done, similar to your setup but the solder unsticks probably from heat and then on the next weld a big spark happens and blows the terminal I used the proper flux for aluminum terminals and the solder and wire sticked really well https://imgur.com/a/s7h18lx

    kWeld - "Next level" DIY battery spot welder

    I actually bought the ones you recommended, calibrated the welder and the 2nd day of welding they broke beyond repair Then I took apart a new 5ah 75c panther and soldered 8awg wire from one terminal to the other and connected it in series and they still keep blowing the terminals up I'm...

    I keep blowing my lipos, will i reduce the time required to make the weld by increasing their voltage? And there by reducing the heat and stress on the thin aluminum terminals Im currently at 3s and can make a 5s batters from the cells I have left that are not broken (all the same 5ah 75c panther)

    I used the same lipo and the internal connections broke inside of it and it became useless. So if it blows your not the only one :D

    kWeld - "Next level" DIY battery spot welder

    I tried powering the welder with a portable car jump starter thats "rated" for 1900A at 12V but it is more 800A, and unusable for welding... I have 10 battery packs in line waiting for me to fix my welder and people are starting to get a little angry.. If you could sell me one of those chargers...

    So he gets different batteries over time? I need something like 30q or 25r or around 15-20a discharge, were there batteries like this before on here?
