SWIT KA-M20S Dual Pocket V-Mount Battery Hotswap Plate

The KA-M20S is an extender plate for SWIT's PB-M series Pocket V-Mount batteries, holding two packs at once so one can be swapped out while the other keeps the camera running. It switches automatically between a lower-draw hotswap mode and a higher-draw mode depending on what is plugged into the camera.

In hotswap mode it caps the camera and D-Tap outputs at 150W each; switch to high-load mode and the V-Mount output rises to 300W, while the D-Tap output stays at 150W and 10A. At 238 grams it adds little weight behind two pocket batteries that are already smaller than a standard V-Mount brick.
