Bottom Line: This Turnigy A-SPEC is an overrated and poor performing pack for its factory rating.
Its internal resistance is about double the average of the other packs I have tested, resulting in extra voltage sag. Discharging this pack at its 117A (65C) current rating would quickly bring the voltage down to about 8V
It can’t even be considered a 65C pulse-rated pack as the first pulse would be near 8V, below the typical 9.0V cutoff for a 3S LiPo pack.
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!
My Ratings:
Capacity = 1800mAh
Continuous Discharge Rating (CDR) = 20A (11C)
Average Pack IR = 36.1mOhms
Average Cell IR = 10.1mOhms
Dimensions/Weight = 103 x 31 x 25mm/ 160gms
IR = Internal Resistance
mOhms = milliohms
