What do I need to pay attention to if I charging a lifepo4 battery  ?

The first thing is to use the right charger, that is, use a charger that meets the specifications of the battery, which requires us to avoid overcharging and over-discharging. There is also the need to avoid extreme temperatures, so avoid exposing the battery to extremely high or low temperatures for long periods of time, which can affect battery performance and cycle life. Lastly, don't deeply discharge the battery, try to avoid discharging the lifepo4 battery completely, and don't charging the lifepo4 battery only when it's completely empty, charging it in a timely manner will help to extend the life of the lifepo4 battery.

Why can't we use LiFePO4 batteries in extreme temperatures?

The activity of the cathode material decreases at low temperatures, making the number of lithium ions that can move to bring discharge current decreases, which is the root cause of the decrease in capacity. At low temperatures, the diffusion movement of charged ions in the positive and negative electrode materials deteriorates, and the internal resistance of the battery core rises. This higher resistance makes it more difficult for the battery to supply the required current, which leads to a drop in performance. For these reasons, it is not recommended that users use liFePO4 cells at such extreme temperatures.


Comparison between liFePO4 cells and NCM cells

First of all, the safety of lifepo4 cells is higher than that of NCM batteries, and then compared with NCM batteries, liFePO4 cells have a cycle life of 1,000-3,000 cycles, which is an advantage that consumers will like because it is more cost-effective if it has a longer life. Moreover, lifepo4 cells are environmentally friendly material, which also caters to some consumers who insist on green concepts. However, NCM batteries contain cobalt, which is not as green as lifepo4. So using lifepo4 cells is a good choice
