FXLION’s First 28V B-Mount Battery Announced

FXLION's First 28V B-Mount Battery Announced

FXLION has recently released their first-ever B-Mount battery. This high-voltage (28.8V), high-capacity (293Wh) brick is compatible with the new ARRI ALEXA 35 and is designed to power the most demanding cinema cameras and lights. It offers D-Tap, USB-A, and USB-C output ports. Let’s take a closer look.

Born out of the collaboration between Bebob and ARRI, the B-Mount power system first saw the light in 2019. These new batteries offer a higher voltage compared to traditional V-Mount/Gold-Mount bricks. They are designed specifically to feed today’s and tomorrow’s power-hungry cameras and lights. If you want to learn more about the advantages of this new standard, don’t miss this ARRI Tech Talk as well as the interview we conducted with SWIT.

Following the release of ARRI’s new S35 flagship model, the ALEXA 35, FXLION decided to attend the party by releasing their first B-Mount battery model. The Chinese manufacturer, which is already well-known for their compact V-mount cells, now joins the list of companies supporting this new standard. Let’s take a closer look.

FXLION embraces the B-Mount battery standard

This new FXLION B-Mount model (product code: BM-HV300) is a high-voltage power brick (28.8V) whose large capacity of 293Wh can power cameras and lights for an extended period of time. For reference, the new ARRI ALEXA 35 has a power consumption of approximately 90W (when using the MVF-2 viewfinder).

The battery features the typical side-loading mechanism of a B-Mount battery and offers several different outputs for powering additional accessories. These include two D-Tap output ports on the side (16V 60W Max, DC16V Constant) as well as a single USB-A (5V/2A – 10W Max) and USB-C (5V~20V/3A – 60W Max) at the top.

The design is pretty simple but seems rugged overall. Unfortunately, this new model lacks a status display, which is something I love about the FXLION V-Mount NANO Series. However, users can still get an idea of the remaining battery life thanks to a 5-stage LED placed at the top.
