Looks like there may be a market for a battery saver/fuse, *begins furiously planning* I wonder if Ranglebox would stock it. Connect to both the battery power connectors and balance port and disconnect the battery on over current, over voltage or under voltage.

Anyway tried connecting up except this time with the battery supplying it so as to provide a near limitless source of amps however it just went berserk. This is bad, I'll try and get an oscilloscope on it tonight to see what's happening.
