Description
BAK 13S 48V 200Ah 13S40P 3C Lithium-Ion Rechargeable Battery Pack
The BAK 13S 48V 200Ah 13S40P 3C Lithium-Ion Rechargeable Battery Pack is a high-capacity lithium-ion battery solution designed for electric vehicles, industrial equipment, solar energy storage, backup power systems, electric utility vehicles, and other high-energy applications.
Built using BAK 21700 5000mAh lithium-ion cells, this battery pack uses a 13S40P configuration, consisting of 520 individual cells. It provides approximately 46.8V nominal voltage, commonly marketed as a 48V-class battery, with a total capacity of 200Ah and approximately 9.36kWh nominal energy.
13S40P Battery Configuration
The 13S40P configuration contains 520 cells:
- 13 cell groups connected in series
- 40 cells connected in parallel per group
- 13 × 40 = 520 cells
- 40 × 5Ah = 200Ah
- 13 × 3.6V = 46.8V nominal
- 13 × 4.2V = 54.6V maximum charging voltage
- 46.8V × 200Ah = 9,360Wh / 9.36kWh
This makes it a very high-capacity 48V-class lithium-ion battery pack.
High-Capacity 200Ah Lithium Battery
With 200Ah capacity, this battery pack is designed for applications requiring substantial stored energy and longer operating duration.
Its approximately 9.36kWh nominal energy capacity makes it suitable for larger electrical systems where a standard 48V 20Ah, 50Ah or 100Ah battery may not provide sufficient energy.
Actual operating time depends on the connected load, motor/controller efficiency, environmental conditions, battery age, and operating profile.
BAK 21700 Lithium-Ion Cells
The battery pack uses BAK 21700-format lithium-ion cells arranged in a high-capacity 13S40P configuration.
The large number of parallel cells helps distribute the required current across multiple cells and provides the 200Ah pack capacity.
3C Discharge Capability
A 3C rating means the theoretical current corresponding to the pack capacity is:
200Ah × 3C = 600A
However, this does not automatically mean the finished battery should be operated continuously at 600A. The actual allowable continuous and peak current must be determined by the specific BAK cell model, BMS, nickel/busbar design, wiring, connectors, thermal management, and battery enclosure.
For this reason, the BMS and pack current rating should be selected according to the actual application requirements.
BMS Protection
A suitable 13S Li-ion BMS can provide protection and monitoring functions such as:
- Overcharge protection
- Over-discharge protection
- Over-current protection
- Short-circuit protection
- Cell voltage monitoring
- Cell balancing
- Temperature monitoring, when supported
- Battery fault protection
For a high-capacity 200Ah battery, the BMS, busbars, wiring and connectors should be appropriately rated for the intended current.
54.6V Charging Requirement
This is a 13S lithium-ion battery pack.
Therefore:
Nominal Voltage: 46.8V
Maximum Charge Voltage: 54.6V
A compatible 54.6V Li-ion CC/CV charger should be used.
Do not use a charger intended for a different lithium chemistry or an incorrect charging voltage.
