That can't be true unless you were overdriving the 2200 battery so much in your tests that you were probably damaging it.
However- he could have drawn the same Amps for a considerably longer time. I suppose it's possible that a temperature the motor can handle for 2-3 minutes would damage it in 5-6.
Good to hear that you replaced the motor in any case!
