Gemini 2-Cell Battery 30Wh 8.4V USB-C Rechargeable Lithium Ion Battery

Gemini's 30Wh 2-cell battery jams a lot of power into a small package. Rated at 4000mAh, this super high capacity lithium-ion cells set a benchmark for energy density. Adopting USB-C as the new standard, it's impossible to plug in the charging cable upside-down. In addition, the smart USB-C port also allows for the charging of other devices, making this a portable power bank in addition to powering your Gemini lights. A durable outer shell made of high strength polycarbon has yielded an increase in double the impact protection from the previous generation.
