Voltage note: With 3.6V nominal BAK cells, the calculated electrical nominal voltage is 46.8V, commonly sold as a 48V-class battery. Full charge is 54.6V (13 × 4.2V). BAK’s cell specifications confirm the 3.6V nominal and 4.2V maximum charging voltage.
Capacity & Energy Calculation
Cell capacity: 5Ah
Parallel configuration: 12P
5Ah × 12 = 60Ah
Total cells:
13S × 12P = 156 cells
Approximate nominal energy:
46.8V × 60Ah = 2,808Wh
So this battery provides approximately 2.81kWh of nominal energy.
Applications
- 48V E-bike battery systems
- Electric scooters
- Electric motorcycles
- Electric carts
- Electric vehicles
- Industrial vehicles
- Robotics
- Solar energy storage
- Portable power systems
- High-capacity backup power
- Custom EV battery packs
- Industrial battery systems
BMS & Charging
A 13S Li-ion BMS is recommended to provide cell-group monitoring and protection against conditions such as overcharge, over-discharge and excessive current.
For charging, use a dedicated 54.6V CC/CV Li-ion charger suitable for a 13S NMC/Li-ion battery pack.
Important Safety Note
This is a high-energy lithium-ion battery pack. Proper BMS protection, cell matching, insulation, interconnects, enclosure and charging equipment are important for safe operation. The pack should be assembled and serviced by a qualified battery-pack technician.
