SmallRig T221 Triple-Proof V-Mount Battery 5865

The SmallRig T221 V-mount battery pairs 221 Wh with a rugged body: 1.8 m drop resistance and an IP54 rating. It powers a whole rig at once: one BP port, four D-Tap, two USB-C with 140 W PD3.1 and a USB-A. A full charge takes 2.5 hours, shown on the OLED display.

The SmallRig T221 Triple-Proof V-mount battery 5865 is built for full days on set, where powering the rig piece by piece stops making sense. Its 221 Wh (14.76 V / 14,910 mAh) rest on twelve LG cells and a BMS control chip that watches for overheating, overcurrent, over-voltage, short circuit, overcharge and over-discharge. The body survives a 1.8 m drop and carries an IP54 rating against dust and splashing water — an anti-slip TPU layer and a metal frame shield the cells from impacts. It feeds the whole setup at once: one BP port, four D-Tap, two USB-C and one USB-A. Both USB-C ports handle 140 W under PD3.1 in either direction, so the battery reaches a full charge in 2.5 hours and delivers the same power to a laptop or a camera. A graphene layer with thermal compound moves heat away so the rate does not drop during fast charging or discharging. An OLED display shows the charge level, the remaining runtime and the port voltages, while a backlit indicator helps when mounting in dim light and doubles as an emergency light. The silicone port cover is held by magnets and stays out of the way. Besides the V-mount plate the body carries 1/4"-20 and 3/8"-16 threads for further mounting. A braided one-metre 240 W USB-C cable is included.
