Description:
GOLISI i4 is the upgraded version of our star charger S4, it not only inherits the readout friendly on a large HD LCD screen and durable loading springs, i4 adopts USB power port to charge cylindrical rechargeable batteries of length ranging 32-70mm. i4 has 2 core components: a high efficiency Switching-Mode-Power-Supply and a microprocessor. the two parts convert high electricity voltage into suitable voltage for battery charging. The electro-circuit uses 4 independent output charging modes with which it can charge Lithium-ion batteries, Ni-mh batteries, and Ni-cd batteries in any model and capacity. The current is constant mode and current can be distributed automatically to 4 channels.

LCD display and Operation:
Connecting to power supply without loading batteries, the LCD screen will be bright for 2 seconds then displays “null” which means no batteries being loaded
Charging Status VS Screen Display: loading batteries, the screen displays channel /battery voltage / charging current / capacity rates.  “%” flashes while i2 device is charging, “%” increases until 100% which means batteries are fully charged, i2 cease charging. 
Button Operation: Click the button to check related information of batteries, including voltage / capacity / time.
A long click can keep the screen constantly bright.
Connecting to Power Supply, without batteries, the screen will be bright for 2 seconds then display “null” which denotes no batteries being loaded 
Charging Status and Screen Display: loading batteries, the screen will display channel / battery type / battery voltage / charging current / capacity rate.  “%” flashes mean the device is charging, “%” increases until 100% which means batteries are fully charged, I4 cease charging the battery.
Button Operation: 3-second long click to turn on or turn off the LCD display. A soft tap displays the batteries' charging status including voltage / capacity / time
