EnerSys and Bren-Tronics: powering defence
platforms with multi-chemistry 6T battery solutions
Mathyas Petit, Director International Business Development, Bren-Tronics
As military platforms evolve to support next-generation command, control, and electronic warfare systems, power storage demands are increasing in complexity. From legacy vehicles to new electrified and hybrid fleets, the need for scalable, high-performance and ruggedized energy storage solutions is more critical than ever.
EnerSys, through its Bren-Tronics brand, stands at the forefront of this evolution, offering a full portfolio of 6T form-factor batteries-including both VRLA, AGM, TPPL lead-acid and advanced lithium-ion variants. This multi-chemistry approach enables seamless fleet modernization while maintaining full support for existing vehicles.
A Legacy of Trust, Now with More Power
EnerSys' Armasafe™ Plus 12FV120 AGM battery has long been the benchmark in 12V lead-acid solutions for defense. With the acquisition of Bren-Tronics, the Group now also delivers cutting-edge lithium-ion capabilities, empowering military forces with the flexibility to choose the best energy solution for their mission profiles.
This dual offering ensures that today's fleets can continue operating with familiar, proven lead-acid batteries-such as the Armasafe™ Plus 12FV120, built to support extended legacy vehicle life cycles-while tomorrow's platforms can scale up with high-energy, long-duration lithium-ion technology for silent watch, electronic payloads, and hybridization.
Leading the Way in Lithium 6T Performance: ION-X™
Bren-Tronics lithium 6T batteries have been deployed and trusted in the field for over a decade. Now offered under our new ION-X™ brand, our lithium models meet the latest MIL PRF 32565C amendment 2 specifications - ensuring the highest level of safety, reliability, and military readiness.
Among the key offerings:
- BT-70939M-TPB: A 24V, 105Ah GVSC-compliant battery designed for drop-in replacement, delivering exceptional cranking power and integrated CAN-bus diagnostics.
- High-Energy 24V 6T Battery: Our newest solution offers 162Ah and 4.3kWh, one of the highest energy densities available in the 6T form factor. Ideal for high-demand vehicle systems, extended silent watch, and hybrid energy applications.
These ION-X™ batteries are engineered for rugged use across demanding environments, extreme temperature and vibration conditions and feature smart BMS with CAN-bus communication for real-time diagnostics, system integration, and mission-critical safety.
Supporting Today, Powering Tomorrow
Bren-Tronics understands that defense modernization doesn't happen overnight. That's why we continue to support existing vehicle platforms with Lead-Acid 6T batteries, while providing drop-in lithium options for hybrid adoption strategies. This dual-path support ensures flexibility, cost-efficiency, and mission readiness without compromise.
Whether upgrading entire fleets or adopting a mixed-chemistry approach, our solutions deliver:
- Extended runtime for silent watch operations
- Lighter weight and longer cycle life with lithium options
- Seamless integration with existing 6T battery compartments
- Full diagnostics through CAN-bus BMS
- Rugged performance across extreme battlefield environments
