2A Lithium Li-ion 18650 3.7V Battery Charger DC 5V Converter Module Power Supply

Small size and high current charge-discharge integrated module, charging current up to 2.1A, discharging current up to 2.4A, output current close to 3A when the battery is fully charged, protection will be triggered when overloaded or overcurrent, and the output will be automatically turned off, even when the output is short-circuited. Can be automatically protected! However, all interfaces have no reverse connection protection, and the chip may break down when the wrong polarity is connected!

Note:the output can not be connected to inductive loads such as motors, and it will easily cause the chip to burn out when forced to use it for this purpose! The lead wire connecting the battery to the motherboard cannot be less than 20AWG and needs to withstand 5A current. Although the chip integrates lithium battery protection, it is recommended to add a level of lithium battery protection for special purposes, which is safer!
