With Micro USB socket at the input port, can directly use the phone charger as input to charge for lithium battery, and keep connection solder joint. Convenient to DIY.
After connecting the lithium battery to B+ and B-, join up 5V input, red light indicates on charge, green light indicates fully charged.
The charging current would be better 0.37 times than battery capacity. (eg. 1000mAH battery charging current is 400mA) Disconnect load while charging, OUT / B output positive and negative reverse connection will damage the module.
