Genuine A123's are only made in 1100Mah and 2300Mah are you sure he had A123's and not copies of some sort, also I did read the first post and he had two what he says are 1200Mah batteries therefore he had 2400Mah on board, the likelyhood of a battery failier with genuine A123's is very remote, I know of no known failiers of genuine A123's without some kind of abuse being involved.

Hi Mike, 2400 mAh yes you are right. However, I have assumed that fitting the second battery was to provide mutual redundancy. In this case if a battery or switch fails you would be left with 1200 mAh maximum. Is that enough to reasonably fly the model? If not you need bigger batteries. Start with what battery size you need to provide the power to the whole model, then double it.
