ENEPAQ Expands Module Lineup with Amprius cells

We are excited to announce a major expansion to the ENEPAQ Li-ion Building Block ecosystem – modules with Amprius cells. We have integrated three new, highly requested cell models into our modular architecture: the Amprius SA110, Amprius SA112 and Amprius SA124.

Whether your application demands extreme energy density, massive discharge currents, or extreme-temperature resilience, our new module configurations provide a plug-and-play solution to get your battery packs prototyped and deployed in a fraction of the time.

Here’s what each cell brings to the table:

Amprius SA110 & SA112: Maximum Energy Density

When weight and space are your primary constraints, the Amprius SA110 (18650) and SA112 (21700) modules deliver unmatched gravimetric and volumetric energy densities. These are ideal for specialized weight-critical applications. 

• SA110 (18650): Packs 4.0 Ah per cell, achieving 293 Wh/kg and 818 Wh/L. Max discharge: 12A. 

• SA112 (21700): Packs 6.5 Ah per cell, achieving a massive 312.5 Wh/kg and 876 Wh/L. Max discharge: 13A. 
• Note: Both models support standard operations up to 60°C ambient (70°C cell surface) during discharge. 

If your application requires a balance of high capacity, high continuous current, and extreme temperature tolerance, the SA124 (21700 format) is the optimal choice. 

• High Power: 30A maximum discharge current and 10A fast charge. 

• Extreme Cold Performance: Rated for discharging in environments as cold as -40°C and up to 65°C. 
• Specs (21700 format): 5.0 Ah | 257 Wh/kg | 688 Wh/L. 

No matter which cell chemistry you choose, all new modules are built on the proven ENEPAQ mechanical platform, guaranteeing safety, scalability, and ease of assembly: 

• Integrated Fuses: Every individual cell is protected by fuse-links integrated in the busbar, providing a secondary level of protection in case of cell failure. 

• Built-In Thermal Monitoring: Integrated temperature sensors make physical contact with the negative poles of adjacent cells. 

• Fire-Retardant: Housed in UL94-V0 rated fire-retardant plastics with dedicated gas channeling. 

• Rapid Assembly: Build everything from small backup storage to MWh-scale EV batteries in minutes using simple bolt connections. No spot welding required. 

The new Amprius cell modules are available now in configurations ranging from Li1x1p up to Li1x10p (1 to 10 cells in series), scaling up to Li2x10p for double the parallel capacity per string. 

Note: Not every configuration listed is supported across all cell models – check the relevant datasheet for compliance.
