The B90cineML and the B155cineML have different capacities (86Wh and 156Wh, respectively), but share the same functionality. They can be connected in series with other B-Mount batteries and simultaneously function as dual-voltage high-performance batteries and hot-swap adapters. They automatically take over the power supply to the camera and the D-Tap connection as soon as the connected battery is empty. This guarantees a continuous, uninterrupted power supply during camera operation. Both MLs can be charged either by a plugged-in battery or a B-Mount charger.

The B90cineML and the B155cineML support two different voltages, 14.4V and 28.8V, which means they can be used for 12V and 24V devices. Their continuous power and current output are 450W and 20A, respectively. A five-stage LED display indicates their current charging status. Both batteries are equipped with a Twist D-Tap and a USB-C port. A
