The fee should separate the load OUT terminal on the positive and negative can not be wrong, please according to specifications, otherwise it will damage directly.
The first time access to the battery, there can be no voltage between the output OUT + and OUT-, then access 5V voltage charge your energy can activate the protection circuit, and the battery from the B + B-, then draw a line The short open also need to be recharged to activate the protection circuit. Notice that the charger must be able to output 1A or more when you input a cellphone charger, or cannot charge
+ MICRO USB female and next-pads for the power input, access 5V. B + positive then the lithium battery, B-then negative lithium batteries. OUT + and OUT- connected to the load, such as positive and negative electrodes connected to mobile booster plate or other load.
Connect the battery to the B + B-, inserted into the USB female mobile phone charger, the red light is charged, the green light too full.
Inputs with MICRO USB female, can be input directly to do with the phone charger lithium battery,
And still the input voltage wiring pads, can be very convenient DIY
