High-Capacity Power for Demanding Group 49 Applications
Meet the energy demands of your largest equipment without sacrificing an inch of space. Our Group 49 LiFePO4 battery delivers massive capacity and robust power in the industry-standard size. It's the ultimate drop-in solution for high-performance applications that require serious, reliable energy all day long.
Engineered for Demanding Applications:
Unrivaled Capacity in a Standard Size:
Packing a high amp-hour (Ah) rating into the standard Group 49 (8D) form factor, it provides exceptional runtime for the most power-hungry devices and systems.
Massive Cranking & Reserve Power:
Delivers explosive starting power (CCA) for large diesel engines and ample reserve capacity (RC) to run accessories for extended periods without the engine running.
Built for Heavy-Duty Use:
Features reinforced terminals and a robust casing designed to handle the high currents and vibrations found in commercial and industrial environments.
Superior Cycle Life:
Outperforms and outlasts any lead-acid equivalent, providing thousands of cycles for a dramatically lower total cost of ownership over its lifespan.
