11.1V 3500mAh 3S Cell 30C-60C LiPo Battery Pack w/ EC3 (EC-3) Connector Plug (Airplane Helicopter Quadcopter Multirotor Drone UAV FPV 3S3000-30-EC3 EFLB30003S30)

I installed it in my 1.8 pound Walkera v450 and get 10-11 minute flights with 3.7+ volts left per cell. It's a lot of power for the weight and price.UPDATE: After 50-60 flights, this battery is still delivering full power and instant response to all inputs to the end of 10 minute flights.

Battery checks out as capacity based on a quick charge/discharge cycle. The connector wires however have exposed copper where the shrink-wrapping has slipped away. If the QC has missed this visible problem, I am afraid tho think what is inside. Well, it has to be cheap I guess...

Tested this battery on my blade 350 qx3. It has good run time and being that its shorter then the eflite batter you don't have to work as hard to cram the power connection wires back into the compartment. It's good for leisurely flights but i feel that the discharge rate maybe lower than 30C. My vertical punch out did not ascend as fast as the eflite battery.

1/4 of the size of eflite batts. my opterra 6 ft wing loves it. gives me 300 more mah, less weight, getting well over 20 min flight time with a little wind.

This battery worked great at first, but unlike the Turnigy I normally use, this battery over time lost output power although it still has good run time. I notice a big difference flying my Timber.

Great power for the price

ok

Arrived quick and is exactly as described
