Dynacore D-H290B 290Wh 28.8V B-Mount Battery

The D-H290B is Dynacore's B-mount battery, built at 28.8V to match the Alexa 35's native B-mount voltage rather than stepping down from a 14.8V or 26V pack. At 290Wh it is sized for a full shooting block on the camera it was built for.

It pairs with Dynacore's D-4BMC 4-channel B-mount fast charger for simultaneous multi-battery charging.
