Description
- Support 1-3 series Lithium or LiLiFePO4 battery to charge:
- 1x, 2x, 3x, 4.2V lithium battery (set stop voltage to 4.2V, 8.4V, 12.6V)
- 1x, 2x, 3x, 3.6V LiLiFePO4 battery (set stop voltage to 3.6V, 7.2V, 10.6V)
- Charge Input:
- Wide Input Voltage: 7.5V to 28V
- Support to be charged by solar panel, can follow for maximum MPPT point, also can set this function.
- Also support charger input
- Up to 5A maximum charge current
- 3 Stage smart charge (similar to TP4056. MCP73831):
- trickle current charge, set possible on back side.
- constant-current charge (set by Ics), no need change for default.
- constant-voltage charge (set by Vfb)
- Charge status LEDs:
- charging
- done charging.
Resistor divider for feedback:
- Please notice default Rvfb is 3.3K.
- Change Vfb resistor to set this stop voltage
- All the rest SMD resistors are included in the package.
- Supply VCC should be +2V > Vbat
