Find how many batteries you need for a planned number of shots.
Dividing planned shots by the realistic capacity of one battery and rounding up gives the batteries to bring, with spare capacity counted. Carrying enough batteries avoids running out mid-event, which is especially critical on shoots without recharging options.
