[NSRCA-discussion] Voltage regulatormaintenance/replacement/reliability

[Jay Marshall]

3 cell? Dumb! If you want it to last longer, use 2P or 3P. Also 2P have half
of the internal resistance of a non-p pack.

Yes, and I've had some guys tell me that they are using a 3-cell LiPo  
with a voltage regulator.  Just imagine the heat they are generating.
