Core SWX Helix Max 275 Lithium-Ion Dual-Voltage Battery (275Wh, V-Mount)

This V-mount, 275Wh Helix Max 275 Lithium-Ion Dual-Voltage Battery from Core SWX features simultaneous 14 and 28V dual-volage capabilities for a complete onboard system with high-voltage performance. A maximum load of 20A at 16.8V or 10A at 33.6V makes this battery ideal for powering more demanding equipment builds in cine and broadcast applications.

Helix Max series batteries draw minimal current at their maximum voltage, creating less heat and extending the runtime and longevity of each battery. D-Tap and USB-A outputs power other accessories from monitors to mobile devices. An integrated LCD screen monitors runtime and total battery percentage, while built-in camera communication delivers this data directly to your viewfinder. Wrap-around 3-stage LED indicators provide a secondary way to monitor battery life and charge status. An improved polycarbonate housing is shock-absorbing for maximum durability.
