Product Description


SmallRig VB155 mini V Mount Battery 3581

SmallRig VB155 mini V Mount Battery 3581 is about 70% of the size of a normal V-mount battery, given its highly integrated design which takes up less space, making it lighter and more portable! The highly integrated (fast charging protocol chip + MCU + voltage boost control) BMS chip supports a wide range of mainstream fast charging protocols (PD / QC / SCP / PPS / APPLE-2.4A etc.), bi-directional 65W (Max) USB-C PD fast charging, as well as adaptive voltage boost/ adaptive current regulation etc.! In addition, its customized intelligent BMS system ensures faster and safer charging by providing multiple protections against over-current / short-circuit / over-temperature / over-voltage, etc. Such interfaces as USB-A / USB-C / D-tap / DC 8V / DC 12V /  V Mount are also included for efficient charging / powering of camera / camcorder / monitor / wireless video transmitter / video light / mobile phone / laptop etc., without using a V-mount plate to convert! The BMS chip has a 16bit ADC /  power meter algorithm, together with an MCU and an OLED digital display for you to keep track of the battery's status at all times. Built-in premium high-performance  battery (no inflated capacity), which are rechargeable and stable, meet MSDS / UN38.3 / IEC62133 / UL2054 / UL62368 and other internationally recognized standards, allowing you to capture every moment without burden!
