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-discahrging.
