Run your power-hungry DSLR or video camera and accessories using two Imicro batteries and the A-Vmicro2PD Dual V-Mount Hot-Swap Adapter from IDX System Technology. Designed for using two IDX Imicro V-mount batteries, the A-Vmicro2PD enables you to replace each battery as it is depleted while your components remain running. This plate can be used with an IDX V-mount charger to charge the batteries. The batteries charge and discharge sequentially, automatically swapping to the next battery when the first battery's charging process is complete.
