RAD Power Bikes Going Bust

[PedalUma]

And are the batteries actually at fault or were the ones that caught fire the result of owner abuse? I'm thinking the latter or there would be a lot more of them.

The RAD I am looking at right now has a five pin discharge in the shape of an 'M'. If it was two pin then replacing the battery would be easy, off the shelf. I do not know what the others do or if they are really needed. It looks like three volts, so one red, one black, and a third control or monitoring signal. This is not one of the bad batteries.
