I did it like the instructions said, one at a time. Twist and bend the wires so that they're thick enough to catch. "Once they're in you can't pull them back out." I beg to differ. They slipped right out, then wire memory shoved the black and red together into a dead short, killing the battery. I got 0 on the volt meter.
I ordered four replacements because I can absolutely see this happening again. I know y'all have been doing your absolute best, but there's no way this should have been sent out without an actual battery connector. I think I'm going to try to solder them to some pins and shove the pins in.
Anyone else got tips for making this work?
