1. Recommended Storage Conditions
2. Recommended Charge Level During Storage
LiFePO4 batteries should be stored at a partial state of charge (SOC) between 50% and 80%.
Why Avoid Full Charge/Discharge?
Additional Tips:
Zero maintenance—no watering or equalizing. Just install, register your 7-year warranty, and enjoy consistent, long-lasting power for years to come.
Two 12V 314Ah Mini LiFePO4 batteries connected in parallel and one 12V 628Ah Ultra LiFePO4 battery provide the same total capacity. However, using a single battery system generally offers better consistency and more stable operation. In addition, it requires less wiring and takes up less installation space. To conclude, one 12V 628Ah battery is more recommended.
No, this battery cannot start the car. However, it can be used as an auxiliary battery for the car.
The top cover of this 12V 314Ah Mini Bluetooth battery is secured with glue.
If you would like to purchase a battery top cover fixed with screws, please check the 12V 314Ah Super battery or 12V 314Ah Underseat battery.
