The NiMHs drop their voltage under load more than lipos do, especially when comparing to the flightpowers.

At 100A, FP cells maintain a 3.6v/cell voltage (IIRC), while NiMH can drop to 0.9-1v or less. So, at 100A, the FP pack is at 14.4v, but the NiMHs can be as low as 12.6-14v.

This dropped voltage also creates heat inside the batteries, which reduces their life.
