High voltage protection: when the voltage is higher than 5V, the current will be lower than 1000mAh. It subtracts the charging current automatically to avoid burn damage to chip.

Application:
The module with usb port, can be used directly as a phone charger protection, and still retains voltage input wiring pads, which is convenient for DIY.
It can charge for single-cell lithium battery or multi-section parallelled lithium batteries, can be powered by USB ports.
It can be used for voltage 3.6, 3.7V, etc. polymer and other lithium battery charge and discharge protection.

Note:
There is not included Installation instruction.If you are the first time to do this job, we suggest you can watch related video on Youtube before installation.Tutorial video: https://www.youtube.com/watch?v=Qw4psECqpwI
Please check all connections before charging, it will be damaged directly if the load OUT terminal on the positive and negative with wrong polarity.
Charging current is better to be 37% of the battery capacity. If you want to charge a battery of 1000mAh, 400mAh current will be enough.
When you uses Phone charger to charge, the current input should be up to 1A or more than 1A, otherwise it can not be in normal charged.
