Upgrade Version The input has a Type C female connector, which can be directly input as a mobile phone charger to recharge the lithium battery The input voltage wiring pad is also reserved, which can be very convenient for DIY. Usage The - pads are the power inputs, access to 5V. B connects to the positive pole, B- connects to the negative pole, OUT and OUT- connects to the loads, such as connecting to the positive and negative pole of the mobile booster board or other loads. Application TP4056 module can charge for single-cell lithium battery or multi-section parallelled lithium batteries, can be powered by USB ports The module with USB port, can be directly input to do with rechargeable lithium battery as a phone charger. Note When first accessing the battery, there may be no voltage output between OUTOUT-, at this time access to 5V charging can activate the protection circuit, the battery is disconnected from BB- and then connected again also need to be charged to activate the protection circuit. When using a mobile phone charger as input, the charger should be able to output 1A or above, otherwise it may not charge properly.. Attention The charge should disconnect the load OUT terminal on the positive and negative can not be wrong, please according to specifications, otherwise it will damage directly. Reminder Please check all the connections before charging, it will be damaged if the load OUT on the positive and negative with wrong polarity. If you do this the first time, please watch the video on Youtube before installation.
