iMars S10 G-Tech 10W Portable airsoft charger for LiPo
The Gens ace iMars S10 G-Tech Portable Charger is specifically designed to cater to the needs of G-Tech batteries.
However, it also boasts compatibility with a wide range of non-G-Tech options that are prevalent in the airsoft industry. This versatile charger is suitable for batteries with capacities ranging from a modest 250 mAh up to approximately 3000 mAh. The voltage range it supports includes the commonly used 7.4V, 7.7V, 11.1V, and 11.4V, making it a versatile choice for various airsoft battery types.
Featuring the G-tech connector, the iMars S10 is equipped with an intelligent system that can automatically detect whether the battery is a Higher Voltage version or not. Upon this detection, the charger will then select the most appropriate charging mode to ensure the battery is charged optimally. In cases where the battery is not equipped with a G-tech connector, the charger defaults to a standard charging protocol, setting 4.2 volts as the full charge voltage for each cell. This protocol applies to both regular batteries and those with higher voltage specifications, ensuring a consistent and safe charging experience.
G-Tech Smart Eco
It is the first member of the Gens ace G-Tech Smart Eco, when the Gens ace G-Tech battery is connected to the Imars Mini charger, the charger will automatically identify the battery type, voltage through the smart balance connector, and charging current recommended by the battery manufacturer. The charger will start charging in 5 seconds automatically after G-Tech smart battery is connected.
