The most important point to note while selecting batteries to power bldc motors through motor controllers (ESCs) is that the power supplied to a motor controller is not the same as the power supplied to a bldc motor. The article linked here explains how to choose batteries for motor controllers.
Three points that sum up the article:
- Current: Motor controllers convert low currents into high currents. One must only worry about the voltage and power output of the batteries.
- Since RPM = V * Kv, the battery voltage can be determined by V = RPM_max / Kv * 1.25, where 1.25 is safety margin for the load.
