Ways to Take Care of Your LiFePO4 Battery

Though lithium ion batteries available have been used for many years, these are still used as a popular battery type in many applications. Such as Lithium Marine Batteries,Trolling Motor Batteries, Golf Cart Batteries. Special thanks to the high performance and durability of the battery. The lifepo4 battery lifespan is long. 

So you may use these batteries for almost 10 years or more with a warranty. But make sure to store and charge the battery. The following are some tips to keep your battery performing for many years:

Tip 1: Never overcharge/discharge a cell!

The main reason why your battery fails soon is overcharging and discharging. Experts never suggest you charge your battery above the limit. So avoid overcharging your battery. The reason is even a single overcharge may damage the battery. This way, you can’t claim for warranty and replacement. Make sure to check the lithium battery absorption time.

The battery has an in-built lifepo4 battery system. It ensures that the battery is safe and under limited charging. Moreover, this system balances the voltage in the battery.

The charging limit for lithium batteries is 3.5-3.6 V per cell. In comparison, the absolute charging is 4.2 V per cell. Never overcharge the battery; otherwise, it will reduce lifespan. Not only this, there are many chances that your battery will get fire.

When your battery gets damaged and catches fire. It means the EV doesn't take responsibility for it. The following are some reasons for overcharging:

  1. Absence or lack of a proper protection system
  2. Fault in the protection system of a LiFePO4 Battery
  3. Improper installation of the protection system

EV Works is not responsible for the use of a protection system. Not only is overcharging damaging, but over-discharging is also damaging. Make sure to disconnect the load when a cell is empty or at 2.5 V. When the cell reaches 2.0 V or less, and it shows mild damage. But you may recover this damage. While when the battery is completely empty. It means you can’t recover the damage.

Tip 2: Clean your terminals before installation

The battery terminals are created from aluminum and copper. So when you expose the battery to air, these chemicals start building an oxide layer. So when you have to install the interconnectors and BMS, make sure to clean the terminals properly using a wire brush. This way, you can remove oxidation. While if an ionic lithium battery has copper connectors, you should also clean them.

After cleaning the battery and other areas, you see improvement in conduction. Not only this, there are minimum chances of heat buildup. If the heat starts building up, it may melt the plastic of terminals and damage the system.

Tip 3: Use the right terminal mounting hardware

Cells with M8 terminals use 20mm long bolts. In comparison, the cells with 6M terminals use 15 mm bolts. So make sure to check the depth of the cell. This way, you may get assurance that the bolts are near but don't hit the hole. Moreover, you need to have a spring washer and a flat washer. You may also ask the experts for lithium battery recycling.

Make sure to check the terminals and bolts after installation. If possible, check the bolts after a week if these are tight. In comparison, the loose terminals may cause high resistance and more heat.
