2. Current- 1A adjustable.
3. Charge precision- 1.5%.
4. Input voltage- 4.5V-5.5V.
5. Full charge voltage- 4.2V.
6. Led indicator- red is charging blue is full charged.
7. Input interface- mini USB.
8. Work temperature- -10℃ to 85℃.
9. Inversed polarity- NO.
- 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 1000mAH, current 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 high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-substract the charging current to avoid burn damage to chip.
- NO Reveral polarity
- 1 x 5V Mini USB 1A Lithium Battery Charging Board Charger Module IN 4.5V-5.5v
