Mini USB Lithium Battery Charging Board Li Ion Li Po Charger Module

Mini USB Lithium Battery Charging Board Li Ion Li Po Charger Module 5V 1A CC CV. USB Lithium Battery Charging BoardCharger Module 5V 1AIn order to Charge your Li-ion battery, this device needs 5V mini USB power supply, and this will charge the battery directly.RED led Glows while charging,BLUE Led glows when Full. Description: Charge module- Linear charging Current- 1A adjustable Charge precision- 1.5% Input voltage- 4.5V-5.5V Full charge voltage- 4.2V Led indicator- red is charging blue is full charged Input interface- mini USB Work temperature- -10 to +85 Inversed polarity- NO Size- small 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 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 polarit
