ProMaster USB-C NP-F970 Sony Lithium Ion 7.4V 6800mAh Battery

ProMaster 6,800 mAh NP-F570 Li-ion Battery: The Ultimate in Charging Convenience
This ProMaster 6,800 mAh li-ion rechargeable battery might just be the most convenient camera battery you’ll ever own, thanks to its integrated USB-C charging port. Simply connect it to any USB-C power source, and an on-board LED light will change from red to green when charging is complete. It’s that easy! A USB-C to USB-A charging cord is included for your convenience, and it works with USB power sources providing as little as 0.5A (up to 3.0A max).

Unparalleled Versatility and Design
This battery is compatible with cameras, lights, and other accessories that use the Sony NP-F570 battery type. While it features its own built-in charging port, it also works seamlessly with traditional external chargers. The advantage of the integrated USB-C port is clear: no more fumbling for or losing dedicated chargers. Just use a common USB-C cable (we’ve included one!) for hassle-free charging wherever you are.

The battery comes packaged in a terrific case that doubles as a protective storage unit. This ensures your battery stays clean and its contacts are protected from accidental contact or damage during storage and transport.

Advanced Safety and Performance
Designed with your safety in mind, this battery includes multiple protection features: overcharge and over-discharge protection, overcurrent protection, overvoltage protection (voltage regulation), and short-circuit protection. It utilizes the highest-grade cells available for maximum charging cycles, and a full charge from depletion takes approximately 5 hours and 10 minutes (with a 0.95A minimum charging current).
