Fly with Larger Capacity
The FlyDuo KA-M20C combines 2× 14.4V Pocket V-mount batteries into a regular-size 14.4V V-mount, delivering longer runtime or higher load capacity. The two individual batteries can be carried onto flights in compliance with IATA regulations. The 2× D-tap outputs and 1× USB-C 100W output make it easy to power multiple on-camera devices simultaneously.
Wide Compatibility
The FlyDuo KA-M20C is widely compatible with SWIT's full range of Pocket V-mount batteries, including the PB-M98S/M146S, MINO-S140/S210, and OMNI-50S/99S, as well as the Mini-size V-mount batteries from other brands.
One-by-One Hotswap Mode
When the power draw of the connected device is lower than a single battery's load, the two batteries are used one by one—when one is depleted, switch to the other—enabling uninterrupted hot-swap power. The battery level indicators clearly show which battery is currently discharging.
High-load Mode with dual batteries
When the power draw of the connected device exceeds a single battery's load, the system automatically switches to dual-battery mode, constant load 250W/20A. Both battery level indicators flash simultaneously to show that both batteries are discharging at the same time.
2× D-tap and 1× USB-C 100W out
The FlyDuo KA-M20C provides 2× D-tap outputs of 10.8-16.8V 10A each, and 1× USB-C PD 5V/9V/12V/15V 3A;
20V 5A, Max 100W output, to power more devices simultaneously.

We provide a 1-year conditional warranty, and the following damages/issues are not covered under warranty:
(1) Any damage or malfunction caused by use, maintenance, or installation not in accordance with the User Manual's instructions, including improper battery insertion or removal, incorrect polarity connection, exposure to moisture or conductive debris, or disassembly/repair without authorization of SWIT.
(2) Any damage caused by using third-party batteries, power sources, or accessories that do not comply with the recommended electrical specifications (e.g., voltage, current, or contact pin configuration), including but not limited to electrode overheating, melting, arcing, or short circuits resulting from incompatible battery design or poor battery quality.
(3) Any damage caused by irresistible factors (such as earthquake, fire, lightning, flood, etc.) or human factors including dropping the plate, impact damage, forced battery removal at incorrect angles, or insertion of damaged or deformed batteries.
(4) Any damage or malfunction not caused by the product's design, workmanship, or manufacturing quality — including normal wear and tear of spring-loaded electrodes, contact pins, locking mechanisms, or surface finish scratching.
(5) Electrode breakage, bending, or deformation resulting from violent use, excessive force during battery attachment or detachment, or improper alignment of the battery onto the plate is specifically excluded from warranty coverage. This includes snapped, crushed, or pushed-in contact pins caused by user mishandling.
(6) Electrical or thermal damage (including melted plastic around electrodes, burnt contacts, or discoloration from heat) that is determined to be caused by a third-party battery's internal short circuit, over-current draw, overheating, or defective connector design shall not be covered under this warranty. Such conditions are the responsibility of the battery manufacturer.
