4. Backup Power for Home and Business: They can be utilized as a backup power source for homes, businesses, or critical systems in case of power outages.
5. UPS (Uninterruptible Power Supply): LiFePO4 batteries can be integrated into UPS systems to provide reliable and long-lasting backup power for critical equipment.
1. Using Solar Panels
The LiTime 12V 280Ah battery can be fully charged by in one day (with effective sunshine 4.5hrs/day) by 1200W solar panels. It may take more than one day to fully charge the battery by â„1200W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.
2. Generator/Alternator
If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: â 56A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ⥠140A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
3. LiFePO4 Smart Chargers
To charge 12V battery, it is recommended to use 14.6V battery charger. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: â 56A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ⥠140A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.Related reading: Can I Charge LiFePO4 batteries with a Normal Charger?
It would take around 12.3h to charge when using 12V 20A lithium battery charger
It would take around 6.1h to charge when using 12V 40A lithium battery charger
LiFePO4 batteries can safely charge between 0â to 50â / 32â to 122â.. LiTime 12V 280Ah LiFePO4 batteries include the low-temperature charging protection which will automatically cut the battery charging off when the cell temperature is lower than 32â, thus preventing the battery cells from damage when charging under the freezing point.
It is recommended to store LiFePO4 lithium batteries at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 3 months. Recommended storage environment: 10âïœ35â (50âïœ95âïŒïŒ45%RHïœ75ïŒ RH
No. LiTime LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices. If you need a starting battery, learn more about LiTime marine starting battery.
