The customised DJI Ronin Battery 3400mAH is easy to install and simple to charge.
Remaining power can be checked directly on the battery. Overcharge and over-depletion protection is built in, as is individual battery cell charge balancing.
Expected runtime is over four hours, depending on the attached camera rig and gimbal usage. Note that correct balancing of the rig will assist in giving the best possible battery life.
