The standard temperature for storage should be between -25° C to 60° C. Keep the batteries away from direct sunlight, and it is preferred to store them indoors at safe places away from children. Although the battery has very low discharge rates, its charging should be kept in check and recharged if required.You can look at follow video link about how to store lifepo4 battery pack。

10. What are the handling precautions for using a LiFePO4 battery pack?

As described earlier, Lithium batteries are the safest and reliable chemistries found on the market. The use of these batteries has become usual in our daily life. However, Lithium Iron Phosphate batteries are the most stable and safe ones still a few precautions should be followed while using them.

• Put away from heat:

The best temperatures for the batteries to work is the one comfortable for humans. The best temperature a LiFePO4 battery can work at falls between 20°C to 60°C. The electrodes may start to fall once the temperature passes by 40° C but the Lithium iron phosphate batteries are designed in a way to withstand up to 60° C but a difference in performance may be seen. The battery overheats at unwanted high temperatures that result in the battery malfunctioning. Such factors cause the battery to not perform accurately and die before time.

• Proper storage:

The Lithium iron phosphate battery should be stored under proper and likely conditions. Keep the battery stored away from heat or direct sunlight. The battery should be charged before storage and checked in between if stored for longer intervals. The area where the battery is stored should be dry and well ventilated for a safe storage period.

• Battery checkups:

Look out your battery pack for any physical changes. Look out for a bump on your battery pack, an infrequent odor changed color or anything that is not common. Get the battery checked as soon as possible if you notice any of such things. Do not try to treat it on your own and if needed, replace your battery. Treating a damaged battery pack on your own can cause very dangerous and unwanted situations.

• Charging intervals:

Charge the LiFePO4 battery in short intervals. Do not overcharge the battery and do not let the battery drain completely before recharging it. The battery has a protection system that keeps it from overheating or overcharging. However, such factors may destroy the battery’s capacity to hold a charge with time.

• Avoid freezing temperatures:

The greatest challenge of all is to operate a battery during cold temperatures once the temperature falls below -5° C, the Lithium iron phosphate battery only delivers 50% of its capacity, and as the temperature falls it eventually stops working. Freezing temperatures abrupt the chemical reactions inside the battery pack which dismisses the working flow of the battery. Charging in such temperatures can also be a huge task as the battery can be damaged greatly. Wait for the surroundings to become warmer before charging your LiFePO4 battery pack. If it is pushed to work or charged in such conditions, the battery will fail to do so and die.

11. Can you charge 48v LiFePO4 battery packs with solar panels?

The LiFePO4 battery can be charged through solar modules, but solar charge controllers are required. Like simple battery chargers, it flows the current into the battery storage until it is completely charged. It prevents overcharging and has profiles specifically for LiFePO4 batteries.

The lithium-based batteries should not be charged in extremely cold weather as their capacity to hold charge decreases due to the cold weather. However, the LiFePO4 Batteries are manufactured to be charged and operated in extreme temperatures, but it may affect the battery working overtime. The least temperature suitable to charge the LiFePO4 Battery is 0°C. For healthy battery charging, you should wait for the surrounding temperature to be a little warmer before putting your battery on charge for a healthier lifespan.

14. What happens if you discharge the LiFePO4 battery pack completely?

LiFePO4 Battery packs have an edge over the other lithium-based batteries as they are stronger, safer, and long-lasting. They can be discharged completely with no long-term effect. Although it is recommended to discharge 80% of the battery’s power before giving it a recharge. They do not require partial charging or charging after each use. They do not get damaged easily. Whereas the other lithium batteries and lead-acid batteries should not be discharged completely because the battery cells die and it is quite difficult to revive them.

15. How can you choose the correct LiFePO4 battery pack?
