I'd removed my bbs01b and its hailong battery pack and taken the four pin battery connector out of the caddy, I was intending to test connections and accidentally inserted the four pin connect backwards for less than a second which caused the female connectors on the battery to weld to the male pins on the negative terminal... gave me quite a fright.

I can't see any obvious damage to the battery pack, heatshrink, terminals and cables look ok and it's still reading 41.xx v, though i haven't pulled it out of the shell as it's got white hard blobs of something holding it in (i'd be keen to know what this stuff is if anyone knows).

Not sure if the battery has a fuse but would either the motor or the battery likely to have been damaged?
