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)
