SmallRig 5537 adapter plate kit for NP-F type batteries for 15mm LWS rods (supports UPS)

The SmallRig 5537 adapter plate kit powers mirrorless cameras, monitors and other equipment from one or two NP-F batteries. With two batteries installed, one can be replaced without shutting down connected devices, providing an uninterruptible power supply (UPS).

D-Tap, DC and USB-C outputs power multiple devices simultaneously, with ports positioned to avoid obstructing camera controls and top handles. The USB-C port accepts up to 36 W input, allowing the plate to serve as a charging dock. During discharge, the management chip uses the lower-charge battery first, then switches to parallel output at low voltage to support battery changes and high-demand devices. During charging, it prioritises the higher-charge battery before charging both simultaneously.

A single press of the power switch checks power status and activates output; holding it for 2 seconds disables all outputs without unplugging cables. Separate LED indicators show each channel's battery status.
