30Pcs Mini 1A Lithium Battery Charging Board Charger Module USB Interface Description: Charging method: linear charge 1% Charging current: 1A adjustable Charge accuracy: 1.5% Input voltage: 4.5V-5.5V Full charge voltage: 4.2V Charging indicator: Red charging green full charge Charging input interface: Mini USB Working temperature: -10°C to +85°C Reverse: NO Size: 25 x 19 x 10mm Note: 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 long. 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. Input reverse has no effect on the chip, but the output (battery terminals) reverse will burn chips. Applications: This module is used for single-or multi-section parallel lithium lithium rechargeable battery, charging from the USB port to take power. Package included: 30 x 1A lithium battery charging module
