How many Chinese LiFePO4 battery manufacturers do you know?

The lithium iron phosphate batteries (LiFePo4) are a further development of the well-known lithium-ion battery technology. This means that no memory effect occurs here either, which means that charging or reloading is possible at any time. However, the development was carried out with the proviso that the known disadvantages of lithium-ion technology should be overcome.

Complete Guide to Manufacturers

There are many manufacturers of each battery but you must try to find a valuable source for the quality product. In order to make this task easier, we have the complete guide for you in this article. You may check the Best Lifepo4 Battery Guide for battery recommendations along with their specified features.

 

Battery Performance

Practical use has shown that LiFePo4 still has a remaining capacity of 80% even after 1500 charging cycles. It is also characterized by high cycle stability, which means that intensive use and consistent utilization of the available capacity do not stand in the way of the service life. Lithium-ion batteries quickly lose their original performance and life expectancy if their capacity is often completely exhausted – keyword: deep discharge.

 

Speed ​​stable

LiFePo4 batteries offer a better voltage level, which means that the voltage drop over a discharge cycle is less pronounced than when using conventional lithium-ion technology. Due to the higher voltage, the top speed also remains at a higher level.

 

Battery Maintenance 

A thermal runaway, which in the worst case can lead to an explosion of the battery, is not possible with LiFePo4. Due to this property, LiFePo4 batteries can also be transported by air freight; this is not possible with traditional lithium-ion batteries.

 

Application area

Conventional lithium-ion batteries work optimally in a temperature range of 18 ° to 25 ° Celsius. Below 10 ° Celsius, there are significant performance losses so that the guarantee of longer operation of drive motors is not given. Furthermore, the operation fails completely from a temperature of 0 ° Celsius.

The use of LiFePo4 technology, on the other hand, enables operation beyond -20 ° Celsius. This means that nothing prevents you from using your own electric bike in autumn and winter.

 

LiFePO4 vs. Lead-acid batteries

LiFePO4 batteries have clear advantages over common lead-acid batteries in terms of cycle stability (service life), dimensions, energy density, and weight.

Compared to conventional lead-acid batteries, LiFePO4 can be almost completely discharged without suffering major voltage drops. While a lead battery can deliver around half of its nominal capacity, the nominal capacity of a LiFePO4 battery is almost also the real capacity that can be drawn.

The LiFePO4 battery is also characterized by a comparably long service life. The Enerpower batteries can achieve 2000 complete charging cycles without hardly any loss of capacity and voltage (DOD 100%).

LiFePO4 battery pack has an internal BMS (battery management system). If the battery works above the specified values, the BMS stops operating the battery pack. Excessive charge, excessive discharge, overheating, or overvoltage – the BMS switches them off. The battery stops working. So, the LiFePO4 battery pack is the ideal battery for you.
