The HB-C420S is a 28.8V high-voltage V-mount battery engineered for extreme power demands in cine lighting and professional video production. With a massive 420Wh (14.6Ah) capacity, it delivers a constant 500W/20A output and peaks at 650W—making it ideal for powering high-draw LED fixtures such as the ARRI Skypanel, Aputure Nova, and Creamsource Vortex series.

Built with 24 high-capacity Li-ion cells, the HB-C420S ensures long runtimes even under heavy loads. It supports 100W/3A ultra-fast charging via DC 33.6V input, reaching 80% charge in just 3.9 hours and full charge in under 5 hours when paired with the SWIT PC-P461S charger. The battery features a 5-level LED power indicator and multiple circuit protections for safe, reliable operation.

Its rugged housing is designed for field durability, and the standard V-mount interface ensures compatibility with a wide range of professional gear. The HB-C420S is also compatible with dual battery adapters like the TD-R230S, enabling 48V output for lights requiring higher voltage input. Whether used solo or in tandem, this battery is a powerhouse solution for mobile lighting setups.
