RE: short course truck
or you could just throw on a $3-4(shipped) lipo low voltage alarm that they sell commonly on ebay. I own a few of the alarms for my brushed models that I use lipo on, and IMO its better then a LVC as it starts to alarm once one of your cells hits 3.4 volts, not when the total is around 6.4V's like a LVC does where one cell could be 2.8V, and the other could be at 3.6 if they are out of balance.
