I was spot welding, and all was good, then I went to have some cheesecake and returned after an hour and suddenly I would get low voltage errors from my spot welder and would hear pops inside the lipo
I waited 30 min to see if it would catch fire or not and then decided to open it up and one of the aluminum strips was broken im kinda skeptic to try and solder it together since its very short on one side
Those tabs can only be soldered with aluminum solder. You are better off spot welding it. It is fixable for sure. Just need to cut away a bit of the silver casing to expose some more of the tab.
It broke just after the spot weld, almost st the beggining, this is my first time dissasembling a lipo so its kinda scary
How much can i remove of the silver wrap?
First thing for safety is to get some locking pliers to hold those broken tabs together, and discharge slowly to about 3.3 volts. If you have a oops moment it probably won’t be a memorable event. If you do the repair soon after that and bring the voltage back up slowly there won’t be battery damage. I’ve had a few broken tabs like that, but wasn’t worth the repair for me.
I need this battery working, and do not have time to wait for a new one, they heat up from welding pretty fast and I need to exchange them every 10 minutes and let them cool down so I can weld non stop
I have a lipo balancer/ discharger so I will empty them to 3.0 or even lower to minimize risk of, thanks for the tip, the burns from batteries aren’t really nice…
