About this product

1.TYPE-C USB input terminal with a female, can be directly input to do with the phone charger rechargeable lithium battery, And still retains the input voltage wiring pads, can be very convenient DIY. 2. It can be used for voltage 3.6 3.7V, etc. 18650, polymer and other lithium battery charge and discharge protection. 3. Input voltage: 5V 4. Charging cut-off voltage: 4.2V ± 1% 5. Maximum charge current: 1000mA 6. Battery over-discharge protection voltage: 2.5V 7. Battery over current protection current: 3A 8. Board size: 17 mm x 27 mm linear charging. It has micro USB female it still retain the input voltage wiring solder joints, can be very convenient to diy specifications: current- 1a adjustable. Charge precision- 1. 5%. Input voltage- 4. 5v-5. 5v. Full charge voltage- 4. 2v. Led indicator- red is charging green is full charged. Input interface- micro USB. Work temperature- -10° to +85° . Inverse polarity- no. Size: 27x17mm. Note: 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 1000ma, it is normal. It is protect function, auto-subtract the charging current to avoid burn damage to chip. 6. No reversal polarity. Package included: 5 x 5v TYPE-C USB 1a 18650 lithium battery charging board charger module • Power Source: Battery, DC • RoHS Compliant • Material: Plastic • Weight: 5
