FAQ
Q: In what applications can I use 12V 280Ah LiFePO4 lithium battery?
1. Solar Energy Storage: LiFePO4 batteries are commonly used in off-grid solar energy systems for storing and utilizing solar-generated electricity.
2. RVs and Marine Applications: These batteries are suitable for powering lights, appliances, and electronic devices in RVs, boats, and yachts, providing a reliable and long-lasting power source.
3. Off-Grid Power Solutions: LiFePO4 batteries can be used for off-grid cabins, cottages, or remote locations where a reliable power supply is necessary.
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.
Q: How to charge LiTime 12V 280Ah lithium batteries?
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 ≥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: ① 56A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 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: ① 56A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 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
Q: Can I pair a Bluetooth Module for this battery to monitor the battery status on the phone?
No. This battery is not compatible with the Bluetooth module. You can use a 500A Battery Monitor With Shunt to keep track of battery status.
Q: Can I charge LiTime LiFePO4 lithium batteries in cold weather (under freezing temperatures)?
LiFePO4 batteries can safely charge between 0℃ to 50℃ / 32℉ to 122℉. 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 32℉, thus preventing the battery cells from damage when charging under the freezing point.
Q: How do I store LiTime LiFePO4 lithium batteries?
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: 10℃～35℃ (50℉～95℉），45%RH～75％RH
Q: Can I use LiTime LiFePO4 lithium batteries as starting batteries?
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. Learn more about Deep Cycle VS Starting Batteries.
REVIEWS
I installed two 280 ah batteries and they seem perfect so far! Incredible difference between these and the 80 ah lead acid deep cycle the Rv came with.
I purchased the LiTime 280Ah as an upgrade for a standard lead acid 77Ah battery in my small camper. The battery was shipped quickly and packed very well. With the sale price and a military discount it was an exceptional value compared to all the other top brands I looked at. The battery constructed well and has exceeded all of my expectations so far. I used it on a 4 day camping trip, it provided all the power I needed and never went below 70% with 300 watts of solar recharge capability. It powered lights, water pump, small refrigerator (during daylight hours), vent fan, radio, and USB charging. I’ll have no problem staying out a week or more with solar help. As a comparison, the original lead acid battery would not last a day while running the refrigerator. I couldn’t be happier with this LiTime 280Ah battery and would highly recommend.
Awesome, easy to install
LiTime 12V 280Ah Plus Deep Cycle Lithium Battery with Low-Temp Protection
This is connected to a 1000W pure sine inverter as a UPS for my CPAP setup. Have been using Li Time since they were ampertime. My old 200amp hr battery became the UPS connected to 1500W inverter for my home network. So both are functioning as expected.
