Battery Management System (BMS)
The built-in BMS monitors current and voltages during charge and discharge cycles. It employs smart balancing algorithms to ensure all cell voltages remain at the same level, optimizing capacity and safety. Protection thresholds include:
- Over-charge protection: 3.90 V per cell
- Over-discharge protection: 2.00 V per cell
- Over-current protection: 290-310 A
- Over-temperature protection: 65° C (Release at 55° C)
- Short circuit protection: Automatically recovers after removal of short
Usage and Maintenance
To ensure optimal performance and longevity, follow these guidelines:
- Connections: The battery supports up to 4 units in series or 4 units in parallel.
- Charging: Follow a Constant Current Constant Voltage (CC/CV) charging profile.
- Storage: Charge the battery every 6 months or as soon as the Open Circuit Voltage (OCV) drops to 12.8V.
- Temperature: Recommended operating temperature is 59°F (15°C) to 95°F (35°C).

Practical help
Common problems
Battery shuts down during operation
This may be due to over-current or short circuit protection. Remove the load to allow the BMS to reset.
Battery not charging
Ensure the charger is set to the correct voltage range (14.4-14.6V) and the ambient temperature is above 32°F.
Low capacity or performance
Check if the battery is operating within the recommended temperature range (59°F-95°F) and ensure it is not being discharged below 11V.
Before use
- Verify the nominal voltage is 12.8V.
- Ensure your charger supports LiFePO4 chemistry with a 14.4-14.6V charging voltage.
- Check that the ambient temperature is within the charging range (32°F to 140°F).
- Confirm your configuration (max 4 in series or 4 in parallel).
- Inspect terminals for secure connection (M8).
Specs in practice
- Self-Discharge Rate
- ≤3%/month means the battery will lose up to 3% of its charge per month when stored, requiring periodic maintenance.
- CutOff Voltage
- 11V is the minimum voltage level; the battery should not be discharged below this point to prevent damage.
Images and diagrams
- Dimensions diagram provides the physical footprint (L 12.8, W 6.6, H 8.5 inches) for installation planning.
- Discharge curve illustrates how voltage remains stable over time at various discharge rates (0.1C to 2C).
- Charging characteristics graph shows the transition from constant current to constant voltage phases.
Model compatibility
- Compatible with up to 4 units in series or 4 units in parallel.
- Not for use with chargers exceeding 14.6V.
- Designed for use in various environments including solar, wind, and mobility applications.
