Featuring two independent charging bays, it can charge two batteries at the same time while monitoring each slot individually. The charger offers selectable 0.5A, 1A, and 2A charging currents, allowing you to choose between faster charging or a gentler trickle charge depending on your battery type.
A built-in display provides real-time charging information for each battery, while advanced safety circuitry protects against reverse polarity, short circuits, overcharging, over-discharging, and over-current damage for reliable everyday use. The BO2 also includes a USB output port, enabling compatible lithium-ion batteries to function as a portable power bank for charging smartphones, tablets, and other USB-powered devices.
Compatible with a wide range of cylindrical lithium-ion batteries, the Basen BO2 delivers dependable performance in a compact and versatile design.
