Why crews pick Block Battery V-Mount
Real V-Lock mounting
V-Mount (V-Lock) plates fit professional cinema and broadcast cameras. Gold Mount and 28V B-Mount options are available too.
D-Tap on board
The LOGOS 150 G gives you dual high-current D-Tap ports for monitors, motors and accessories. A 14V single-channel D-Tap fast charger is available.
Know your runtime
An OLED display shows battery percentage, voltage, current draw and remaining run time, so you swap before you run out.
Travel-ready options
The Protean splits into two isolated 75Wh batteries for carry-on. SLi block batteries disassemble for air travel.
Built and serviced in America
Designed and manufactured in the USA by a veteran-owned, family-owned company. Re-cell, service and trade-in options are available.
Take weight off the camera
V-Mount eliminator plates let an SLi-300 or SLi-D600 block feed your rig from a shoulder mount, 15mm rods or a light stand.
V-Mount batteries, plates and block systems
If you need a slim on-camera pack, the LOGOS-150 G is a 150Wh 14V battery available in V-Mount or Gold Mount, with dual high-current D-Tap and an OLED display. It supports loads from 0 to 150 watts and uses Block Battery chargers only.
