Yup when the A123 dump, it's basically empty. As of late I've vented a couple of my A123's from pulling an overdose of amps in my crt.5. It has a funny smell, but there are no fires and whatnot. When they are overheated at around 160F, they lose some capacity. I'm sure lifecycle goes down quite a bit.

I have one 3s1p pack now in the crt.5 that overheated quite a few time. Once cell voltage is lower than the rest. But I still get 1800mah out before the pack loses its marbles. And under max throttle it still puts out 7.3V(nomadio telemetry).

I asked that question because on the novak web site it said something to that effect

Another feature that can be fine tuned via Novak’s new PC interface is the adjustable Voltage Cut-Off parameter. This feature allows drivers to select a cut-off voltage value among a predetermined range of values for 2S Li-Po and Li-Fe battery packs. This voltage cut-off flexibility can improve a vehicle’s performance, while still protecting a driver’s battery investment.

-thats what it says on the link form this thread
