I believe it is 12.5A per channel and the XXL is double that.

Yeah you do, I had it clipped when it was in Cicatrix at 19.2v then reconnected it for that test.

Haha no worries Jamie, I could try that combo I have set up in the video with the batteries from Cicatrix then, fully charged they are around 22.5v, and if it runs ok on that then I could just use the same type of batteries in both robots, which would be great.
