Hollyland NP-F550Battery (Mars &Cosmo

Hollyland NP-F550 Battery — 3,000 mAh NP-F series replacement battery for Hollyland Mars and Cosmo wireless video transmission systems.

The Hollyland NP-F550 is a rechargeable lithium-ion battery in the industry-standard NP-F form factor, designed to power Hollyland’s Mars and Cosmo series wireless HDMI/SDI transmission units. The NP-F format is widely adopted across broadcast and production equipment, so these batteries are also compatible with many third-party monitors, video lights, and accessories that accept the same footprint. The NP-F550 is the most compact option — ideal for lightweight kit builds where size matters more than maximum run time. Pair with the Hollyland S-HOL-DC01 dual-slot charger for efficient back-to-back location charging.
