1 x 18650 batteries (6000 mAh) you can charge with this charger in parallel at the same time
Only one 18650 batteries (6000 mAh) you can charge with this charger in parallel at the same time
1. Ampere meter can only be connected to 5v input end of the module.
2. 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.
3. The connection wire should not be too thick.
4. Make sure the connect point is good.
5. If the input voltage is too high, like 5.2v, the current will be less than 1000 mA, it is normal. It is protection function, auto-subtract the charging current to avoid burn damage to chip.
6. NO Reversal polarity.
