Battery Configuration Recommendations
For optimal performance, use 4 x 18650 batteries in parallel (high-capacity configuration strongly advised).
CC/CV Charging Workflow (4.2V cutoff example):
Trickle Charge Mode (Battery Less than 3V):
Charges at 300mA until voltage exceeds 3V.
Constant Current (CC) Mode (Battery 3V):
Non-Fast Charge Adapter: 2.5A
Fast Charge Adapter: 4A (max)
Constant Voltage (CV) Mode (Battery =4.2V):
Current gradually decreases until reaching -300mA (charge termination).
Auto-Recharge: Activates if post-charge voltage drops below 4.1V.
Button K FunctionsShort :Activates Type-A port and light-load Type-C port for discharge.
Enables power level display.
Double :Deactivates Type-A/Type-C ports and power display.
With External Power: Only disables output ports (display remains active).
Color: Black
Material: PC
