Connection Introduction:

1.B+: connect with battery positive

2.MB: connect with battery 1 and battery 2 joint

3.B-: connect with the battery negative

4.P+: connect with charging/discharging port positive (charging port/discharging port are commonly used)

5.P-: connect with charging/discharging port negative (charging port/discharging port are commonly used)

Notice:

1. During connection, pay attention to input/output voltage, load current using condition, and make sure that board power consumption will not surpass tolerance consumption

2. When connecting with battery, it may not discharge; in this condition, continuous charging can let it restore to the normal operating state

3. When overcharging battery and overdischarging battery are mixed up, it will become charging and overdischarging state, both of them cannot perform charging and discharging

4. Although this protection board internally installs anti-static protection circuit, please don't force too high static electricity on protection board
