DIY Charger Mini USB 5V 1A Board for 18650 Lithium Battery

DIY Charger for 18650 Lithium Battery Mini USB 5V 1A Board.

Features:

Module Specifications
Charge module: Linear charging.
Current:1A adjustable. Please see the below table for changing the charging current by changing the Rprog resistor

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 +85C
Inversed polarity protection: NO.
Size: 25X19X10mm.

Product features:
1.This module uses sophisticated charging chip TP4056, peripheral circuit is simple and good protection performance, charging high precision.
2.This module fully automated processing machinery, all SMT parts manufacturing, every module will be tested before delivery, high reliability.
3.The current of this module can be adjust themselves, as long as change the fixed resistor in the circuit board, can change the output to 100 ma - 1000 ma, very convenient.

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 protection function, auto-substract the charging current to avoid burn damage to chip.
6. NO Reveral polarity.

Package Included:

1 x Lithium Battery Charging Board 5V Mini USB 1A
