Calb 4S3P Battery Module 2.2 kWh

A CALB 4S3P lithium battery module, 2.2 kWh. Four cell groups in series, three cells in parallel.

The low module voltage makes assembly safer. A single module is not a shock hazard, so modules can be handled and wired individually and the high voltage system only exists once they are connected in series. On a build done outside a production environment, that changes how the work is done.

4S means your BMS needs four cell taps per module, not twelve. The three parallel cells in each group behave as one cell for monitoring.

Check which CALB module you have before buying accessories. This is the 2.2 kWh module. There is also a 2.55 kWh module described as 4S3P, and they are not the same: busbars and BMS connectors differ between them, and the energy figure is the only thing in the name that separates them.

Key specifications

Features

• Modular and scalable, so a pack is built by repeating one known quantity
• Low module voltage, so modules can be handled individually without a shock hazard
• Four cell taps per module, so BMS wiring stays manageable
• Compact enough to be handled by one person

Compatibility

For EV conversions, energy storage systems and off grid applications.

It needs a BMS. The module has no protection of its own. Every cell group needs monitoring and balancing.

Accessories are specific to the 2.2 kWh module. It takes the 16 pin BMS connector, not the 12 pin one used by the 2.55 kWh modules, and our right angle busbar with an M8 stud fits it. Check the energy rating on your own modules before ordering.
