Great video. Could you make a video about this spot welder you are using?

Are you going to make a video how to make the spot welder you are using? Please :)

[@fredericdeniaud3268]

Very nice video, but... i don't know which type/model/reference of blue LED you used...as a charging indicator)
Why has it got 3 pins ? and how is it soldered/connected to the USB-C connector and to the charger circuit ?
Thanks for the information

Is that mini battery cell welding machine ok to use?

[@RusWo]

Hi, which AWG do you use for spot welding and which one is on the accumulator (MOSEWORTH)?

[@fayyazbahrami296]

you have to use power cell with high discharge rate like 10 or 20 c this cel is like 1 or 2 it will be dead soon

[@ARMTechHomemade]

Don't worry this celles have 30A discharge rate, you have fake info about this celles.

Hi! I have a question about your battery packs, I don't see any ways I can reach out for help but I figured I'd try here. I'm not sure what is wrong with mine but I'm quite sure I've done everything correctly.

BMC board may not be good or batteries are not strong enough, some boards may require to double the batteries, 3s=6 batteries, 4s=8 batteries. If BMC not good don't leave batteries attached to it as it will ruin all of them. It happened to me.

Batterien alte ?

The subject explained in the video footage from 7.45 to 9.20 minutes is very unsuccessful. You install LEDs, there is no explanation beforehand. In short, that part is a disappointment.😡😡
