Key Features

  • LiFePO4 Chemistry: 12.8V nominal lithium iron phosphate cells deliver 99% round-trip efficiency with 100% usable depth of discharge.
  • Integrated BMS: Internal Battery Management System provides short circuit protection, over-discharge voltage cutoff, cell balancing, and smart battery-to-inverter communication.
  • 6,000 Cycle Life: Rated for 6,000 cycles at 80% DoD — dramatically outlasting AGM and flooded lead-acid alternatives.
  • Drop-in Replacement: Group 27 footprint with M8 bolt threaded insert terminals allows direct replacement of existing lead-acid batteries.
  • IP67 Rated: Sealed, waterproof and dustproof enclosure for demanding outdoor and marine environments.
  • Scalable: Supports up to 16 units in parallel or 4P x 4S configurations for 24V or 48V battery banks.
  • Low Self-Discharge: Only 3% per month — ideal for seasonal storage and infrequent-use applications.
  • Smart Communication: Battery-to-inverter and battery-to-battery communication for optimized system coordination and monitoring.

Applications

  • Off-grid solar energy storage
  • RV house loads and power storage
  • Marine applications (trolling motors, onboard electronics)
  • Home backup and UPS systems
  • Golf carts and low-speed electric vehicles
  • Energy Storage Systems (BESS & ESS)
