Mamba Max on 4s A123 cells?

[Sammus]

I've been running 4s A123 on 3 mamba max's, two sidewinders, a sidewinder micro and a mamba micro pro all using internal bec, never had a failure or excessive temps.

In fact, I originally tried using a bec, and I think the voltage dip of a123 cells was causing the V input of the bec to drop below its threshold and the Rx was resetting, caused me to have a few accidents. I tried nearly everything - originally i thought it was glitching due to placement of wires etc, but I quickly discovered that wasn't the problem, I tried running ferrite rings and adding capacitors to the power lead side and the Rx power in side (i first tried low capacitance to no avail, and cranked up the capacitance till it was rediculous, still with no fix).

I ended up removing all the caps and ext. BEC and it works flawlessly. Go figure haha.

Anyway, point is, go for it! all the esc's are rated to 12 cell nimh, and ive seen my nimh cells peak at 1.45V, so thats 17.4V input it should be rated for (at least), which is between 4 and 5 fully charged A123 cells. (3.7-3.8vpc)
