- Ampere meter can only be connected to 5v input end of the module.
- It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAHcurrent of 400 is enough.
- The connection wire should not be too thick.
- Make sure the connect point is good.
- If the input voltage is too highlike 5.2vthe current will be less than 1000mAit is normal. It is protection functionauto-substract the charging current to avoid burn damage to chip.
- NO Reveral polarity.
