Bottom Line: This Zippy is a ok performing pack but it is overrated.
Vaping at its 72A (40C) rating, which I am presuming is a useless “pulse” rating and not a continuous current rating, would quickly bring the pack voltage down to about 10V and quickly heat the pack up past the Zippy’s max temperature rating unless vaping slowly. This cannot even be considered a 40C (72A) pulse-rated pack unless the pulses are short and far between and you don’t mind the huge voltage sag at 72A.
CAUTION: LiPo’s use the most volatile of the Li-Ion battery chemistries and can cause extreme injury if abused. Never use a LiPo unless the cells, wraps, wiring, and connector are in perfect condition. Never exceed the CDR of the LiPo unless you understand and accept the risks involved. You are responsible for your own safety, be careful!
