Description
BAK 13S 48V 150Ah 13S30P 3C Lithium-Ion Rechargeable Battery Pack
The BAK 13S 48V 150Ah 13S30P 3C Lithium-Ion Rechargeable Battery Pack is a high-capacity battery solution designed for electric vehicles, solar energy storage, industrial equipment, electric utility vehicles, backup power systems, and custom energy-storage applications.
Using BAK 21700 lithium-ion cells, this battery pack is configured as 13S30P, containing 390 cells. It provides approximately 46.8V nominal voltage, commonly referred to as a 48V-class battery, with 150Ah capacity and approximately 7.02kWh nominal energy.
13S30P Battery Configuration
The 13S30P configuration consists of 390 individual cells:
- 13 cell groups connected in series
- 30 cells connected in parallel per group
- 13 × 30 = 390 cells
- 30 × 5Ah = 150Ah
- 13 × 3.6V = 46.8V nominal
- 13 × 4.2V = 54.6V maximum charge voltage
- 46.8V × 150Ah = 7,020Wh / 7.02kWh
This configuration provides a high-capacity 48V-class lithium-ion battery for applications requiring substantial stored energy.
High-Capacity 150Ah Battery
With 150Ah capacity, this battery pack offers significantly more energy than standard 48V battery packs with lower capacities.
The approximately 7.02kWh nominal energy can provide extended operating time depending on the connected load and application.
Actual runtime will depend on factors such as motor/controller efficiency, connected load, operating conditions, temperature, battery age and discharge rate.
BAK 21700 Lithium-Ion Cell Technology
The battery uses BAK 21700 lithium-ion cells assembled in a 13S30P configuration.
The 30 cells connected in parallel in each series group provide the required 150Ah capacity and help distribute current across multiple cells.
3C Discharge Rating
Based on a 150Ah pack capacity, a theoretical 3C current is:
150Ah × 3C = 450A
However, the complete battery pack should not automatically be considered a 450A continuous battery. The actual continuous and peak current capability depends on the specific cell model, BMS, busbars/nickel connections, wiring, connectors, thermal management and pack construction.
The BMS and battery design should therefore be selected according to the actual application’s current requirements.
BMS Protection
A compatible 13S Li-ion BMS can provide important protection and monitoring functions, including:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage monitoring
- Cell balancing
- Temperature monitoring, where supported
- Battery fault protection
For a 150Ah high-capacity battery, appropriately rated BMS, wiring, connectors and current-carrying interconnects are essential.
54.6V Charging Voltage
Because this battery uses a 13S lithium-ion configuration, it requires a maximum charging voltage of 54.6V.
Nominal Voltage: 46.8V
Maximum Charge Voltage: 54.6V
Use a compatible 54.6V lithium-ion CC/CV charger.
Using an incorrect charger or charging voltage can damage the battery and create a safety hazard.
