NOTE: If you want to change the charging current, please see the below table for changing the charging current by changing the Rprog resistor)
RPROG(k) - (mA)
30 - 50
20 - 70
10 - 130
5 - 250
4 - 300
3 - 400
2 - 580
1.66 - 690
1.5 - 780
1.33 - 900
1.2 - 1000

WARM TIPS:
- Please make sure the battery is well connected.
- Please do not connect the output reversely, otherwise it may burn the chip.
- The connection wire should not be too thin or too long.
- Current meter can only be connected with the module in series with 5V input.
- Charging current is better to be 37% of the battery capacity. If you want to charge a battery of 1000mAh, 400mAh current will be enough.
- High voltage protection, the current will be lower than 1000mAh when the voltage is higher than 5V. It subtracts the charging current automatically to avoid burn damage to chip.
