Micro USB 18650 Lithium Battery Charging Board Charger Module+Protection Dual Functions

USB Lithium Battery Charging Board. Charger Module 5V 1AMicro USB input terminal with a female, can be directly input with the phone charger rechargeable lithium battery. And still retains the input voltage wiring pads, can be very convenient DIY. It can be used for voltage 3.6 3.7V, etc. 18650, polymer and other lithium battery charge and discharge protection. Support charge discharge over current protection; Supports simultaneous charging and discharging;Charge cutoff voltage: DC4.2V1%;Charging mode: linear charge;Working environment temperature: -20-85 degrees CelsiusDescription: 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- Micro USB (general phone charger pin) 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
