High Capacity 780Wh
Professional Power Bank Set

The Hedbox Power Bank set provides a continuous power supply to all units used in the studio and in the field. Using the Hedbox DC Power Cable RPC-DC4X4 XLR female to male (included in the kit) the set provides a constant DC power supply for video, audio, and lighting equipment with total independence of a regular AC power supply.

FULL LED Display Screen

LED display provides a clear, accurate, and precise display of power status, charging status, battery channel status, and power bank mode of all 4 Channels. The displayed charging mode (Adapter UPS LED Light ON) provides a clear insight into which channel (CH1, CH2, CH3, or CH4) of the power bank mode is active. With a bright and intense light, the readout function is enabled in the dark.

DC Out 16.5V / 4.5A

With a 4-pin XLR female connector on the front panel, the GIGABANK system provides extra DC output for supplying constant power to external units like professional camcorders, video monitors, LED lights, and other professional broadcast products. Connected with specially designed Hedbox professional high flexibility power cable RPC-DC4X4-4pin XLR female to male (included in the box), the charger can be used as an AC-DC adaptor of DC 14.5V/4.5A, 75W output.

4-ch Sequential Power Mode

Hedbox GIGABANK offers a 4-channel sequential power mode. It allows you to work with 1, 2, 3, or even 4 batteries in the system. When using a 2-channel battery for power, the system will use the battery in channel 1 first, and then the battery in channel 2 when it is first discharged. If using full power bank mode in all 4-channel batteries, the system uses all 4 batteries in the system, discharging the batteries in sequences 1 / 2 / 3, and finally the last 4th battery. This method provides an uninterrupted power supply without delay.

Charging Technology

Intelligent Charging Systems of MEGABANK integrate the control systems within the charger and the electronics within the battery to allow precision control over the charging process. As a safety precaution with high-capacity batteries, a pre-charging stage (trickle charge) is used. Constant current/constant voltage (CC/CV) charging mode is an effective way to charge lithium batteries.

It is used to charge the battery from 0% to 80% (RED light ON). When the battery is charged to 80%, impulse voltage charging (GREEN Light ON) takes over until the battery reaches 100%. The charger CPU automatically adjusts the charging current to be lower than the max charging current that the battery can accept. When the battery is fully charged, this state is stopped.

High-Quality Aluminium V-lock release

Adopting technology that allowed us to use a high-quality aluminum alloy V-lock release, the lock and unlock provide up to 10,000 cycles for a V-mount battery on the plate.
