Internal resistance testing is a relatively simple way of measuring the health of your LiPo batteries. Internal resistance is the electrical resistance that occurs inside the battery cells themselves as the battery creates electricity. The higher the internal resistance the less current can flow from the battery to your ESC and motor.
