3S 3000 mAh 30A Lion Battery Pack

Roaring power in a delicious compact package for light FPV quad drones and some FPV Goggle set.

Made with love and high quality Samsung 4000mah 40A 21700 Li-Ion cells.


This battery pack is meant for generic applications in the range of 12 V and for long range flight and cinematic shooting.

If used as generic power source, make sure to connect a cell voltage checker to the balancing cable and set the buzzer for 3.0V/cell.

If used as flight battery pack, keep in mind that it performs better with low RPM and good torque motors equipped with the right propeller.

For more information, check your motor's performance chart and find out which prop gives the best efficiency value referred to a 3S battery: that's the right propeller for this battery.

Plan your flight in order to still have 3.0 V/cell when landed: this will keep your Li-Ion battery pack healthy for a long long time.

Select specific Li-Ion program on your balancing charger and charge at no more than 2.0 A.

Stay at 50/55% of your throttle and be smooth when open up. You might want to set your throttle curve in order to have a smoother acceleration.
