IDX 308Wh 28.8V Li-ion B-Mount Battery

The IDX HV-320B is a 308Wh B-Mount battery built for ARRI cinema cameras and B-Mount accessories that need high-capacity, high-output power. It's aimed at camera assistants running demanding builds that draw over 10A, where a standard-capacity battery would fall short. A built-in OLED display and multiple output types keep the whole rig running off one battery.
