Dynacore D-310 310Wh Rugged Mini Battery

The D-310 is the top of Dynacore's Rugged Mini line: 310Wh (21Ah) in the same compact, low-profile housing as the smaller D-95/D-155/D-200, still standard gold-mount or V-mount so it drops onto existing plates. At 14.8V with an 18A max draw it can support roughly 10 hours of run time on a 30W camera.

It is also sold as a 4-battery kit, bundling four D-310 batteries with a matching D-4 quad charger for a full-day power set that arrives ready to charge on one unit.
