Description
The Golisi i2 is a compact two-bay smart charger that makes it easy to recharge different types of cylindrical batteries from almost any suitable USB power source. Its two independently controlled slots allow compatible batteries of different sizes or chemistries to be charged together, while the LCD screen provides clear, real-time charging information.
For faster turnaround, one lithium-ion battery can charge at up to 2A, or two lithium-ion batteries can charge simultaneously at up to 1A each. The charger automatically identifies the installed battery type, selects the appropriate charging current and stops when charging is complete. Temperature monitoring and built-in electrical protections provide additional confidence during everyday use.
