Dynacore DV-4CS 31.7Wh Sony NP-F Style Battery with USB-C

The DV-4CS is a 7.2 V Li-ion pack in the Sony L-series NP-F shape, so it drops into any monitor, LED panel or receiver plate built for an NP-F770. Dynacore rates it for 4400 mAh / 31.7 Wh and a 30 W / 4 A constant load, which is the part that matters when a bright panel is drawing hard rather than a monitor idling.

What separates it from a plain NP-F cell is the connectivity. A USB-A socket puts out 5, 9 or 12 V, and a USB-C port runs 30 W in both directions with BC1.2, QC 2.0/3.0, PD 2.0/3.0, FCP and SCP negotiation, so the same pack charges a phone and recharges itself from a laptop supply without a dedicated charger. A four-level LED gauge reads the remaining charge, and multiple circuit protections cover over-current, over-charge and short circuit.
