I recently remounted my battery (36v 11.4 ah taken from an old A2B Metro) and in the process of doing so, broke off one of the wires that goes from the BMS circuit board to the charger. The break is right at the board, so on the board there is a circle with a silver blob underneath it and about 0.0001" of wire sticking out of the top of the circle.
I am having a bitch of a time trying to solder the wire back to the circle. I am brand-new to soldering at all. I know that ideally there would have been some wire sticking out, and I could just braid the wires back together and solder that joint. But there's nothing - just the copper ring. I tried tinning the ring and all it did was make a mess. Carefully scraped off that mess and tried to solder the wire directly to the ring, and I just get a blob of solder on the wire.
I've seen some YouTube videos about connecting wire to a circuit board and they all seem to say that you want the hole to go all the way through so you can stick your wire through the hole and then solder it to the circle/hole.
Can I just take a drill, core out the circle and the little fragment of wire embedded in it, then put my wire into the copper circle's hole?
Appreciate any help.
