“I have some Rhino 25c 2200mah 3S packs that are exactly the same dimensions as these Ace Power 2200mah 40c 3S packs. These Ace packs also have much thinner power leads.
Flying in a Precision Aerobatics Addiction X the Ace packs look more like they are 1800Mah capacity flying for the same amount of time as my Rhino's (which are 2 years old).
I have not tested the 40c output yet, but based on the capacity differences I don't recommend.”
