Bottom Line: This Thunder Power Rampage is overrated (for its factory rating) but it is an ok performing pack.
Its internal resistance is a bit higher than the average of the other packs I have tested, resulting in a bit of extra voltage sag, but the consistency between the cells in the two packs was the best of the packs I tested. Discharging this pack at its 126A (70C) current rating would quickly bring the voltage down to about 9V. This pack’s 126A (70C) rating can’t even be called a pulse rating.
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!
