SAJ CB3-HVC
Description
Precision liquid thermal loop for multi-cycle daily durability.
SAJ CB3-M20 is a 20.09 kWh commercial liquid-cooled LFP battery module powered by 280 Ah prismatic cells, engineered to deliver precision thermal uniformity (≤2.5 °C) and long-term cyclic durability for SAJ CB3-L261 storage cabinets.
Integrated Liquid-Cooling Thermal Plates
Precision coolant channels keep cell-to-cell temperature differentials under 2.5 °C, extending cycle life under 0.5C/1C loads.
Large-Capacity 280 Ah Prismatic LFP Cells
High-energy-density cell architecture maximizes storage capacity per rack while maintaining superior thermal safety.
20.09 kWh High-Density Module
Forms the fundamental building block for scalable megawatt-hour commercial storage projects.
Intelligent Module-Level BMS Monitoring
Continuously monitors voltage, temperature, and insulation resistance across all 13 series-connected cell groups.
More product details
Air-cooled battery modules develop localized thermal gradients during heavy 0.5C/1C commercial discharge. The CB3-M20 integrates cold plates directly beneath the 280 Ah cells.
- Circulating liquid coolant maintains cell temperature differentials strictly within ≤2.5 °C across the module.
- Extends battery calendar life by over 30% compared to conventional air-cooled commercial modules.
- Quick-connect coolant couplings ensure fast, leak-free module insertion into CB3-L261 container racks.

SAJ CH3 and CB3 Series 75-125 kW datasheet (EN)Product questions
Can the CB3-M20 module be used as a standalone battery without a cabinet?
No. It requires the CB3-L261 cabinet enclosure, coolant manifold, and CB3-HVC controller. The CB3-M20 is an internal rack module. It relies on the external cabinet's liquid cooling chiller/heater, master DC contactor, and CB3-HVC master BMS controller to circulate coolant, regulate voltage, and communicate with the hybrid inverter.
What are the physical dimensions and weight of each module for handling?
770 × 600 × 260 mm; approx. 140 kg. Each module measures 770 mm wide × 600 mm deep × 260 mm high and weighs approx. 140 kg. It is designed with integrated slide rails and lifting handles for heavy-duty commercial rack installation.
