Connection Port illumination

1. B+: Connec to cell's anode

2. B-: Connect to cell's cathode

3. P+: connect to the cell's output or charger's anode

4. P-: connect to the cell's output or charger's cathode

Because of the very high energy density, Li-Ion Battery pack must be connected to a protection circuit module to prevent accidental battery explosion caused by over-charging or over-discharging.
