Batteries are like the heart of your drone. Without it pumping volts into your system nothing would function. The cell count of the drone battery will determine the full voltage of the battery. And the mAH lets you know how long the battery can run. It is important to use the correct battery for your drone as using one with too high of a voltage can damage the drone, and too low of a voltage will not allow the drone to work correctly. Safe battery handling practices are encouraged when working with any batteries. Find your next drone battery right here at RaceDayQuads, Your one stop drone shop.
