How to Store Lithium Batteries

21 Feb.,2024

 

Why is it important to storage charge lithium batteries?

Storage charging is charging your lithium battery to 60% voltage so you can leave it on the shelf for an extended period. Leaving your lithium batteries fully discharged or fully charged will cause the cells to deteriorate and get out of balance. This will cause your lithium battery to lose life cycles or even be rendered useless.

What voltage should you store your LiPos at?

You should store your LiPos at around 60% of the rated capacity or 3.8v per cell. For a 2s pack, that would be 7.6 total volts(2 cells at 3.8v per cell = 7.6v). An 8s pack would be 30.4 volts(8 x 3.8v = 30.4v).

What voltage should you store your Lithium-ion batteries at?

Similar to LiPo batteries, you should store your Li-ion batteries at around 60% of the rated capacity or 3.8v per cell. For example, a 4s or 4 cell battery should be stored at 15.2 volts (3.8v x 4 = 15.2v).

What voltage should you store your LiFePO4 batteries at?

You should store your LiFePO4 batteries at around 60% of the rated capacity or 3.2v per cell. Store your 6 cell (6S) LiFePO4 battery at 19.2v (3.2v per cell x 6 cells = 19.2v).

What is the storage function on my charger?

The storage function on your charger will charge or discharge your battery to the proper storage voltage for you, depending on its current voltage. If you plan to leave your battery on the shelf, plug it into your charger and select the storage function before leaving it on the shelf.

How often should I cycle my lithium battery?

For the best performance and to maximize cycle life, you should use or cycle your lithium batteries once per month. When cycling, perform a full charge and a full discharge cycle. Then charge it back to storage voltage and you’re good to go for another month. This process is essential to prolonging the life of your lithium batteries, keeping them from getting out of balance and becoming dangerous, and will definitely pay off in the long run.
