LiFePo4 battery replace lead acid

A common desire nowadays is to replace a lead acid battery with LiFePO4 in a system which already has a built-in charging system.


BMS & PCM selection

PCM/BMS is the most important part of a lithium-ion battery. The functionalities of different lithium batteries all come down to the smallest details. To ensure the highest quality for every lithium battery in every batch, we manually check-in aspects:

Cell selection has a great impact on the 18650 battery’s work performance and life span as well as its size, which will directly result in customers’ application. That’s why we consider this inspection step very important.

PCBA plays an important role in the whole assembly process. As it works for over-charge, over-discharge, short-circuit, over-temperature.

The last but not least, the assembly artwork shall keep them uniformity, such as voltage, resistance, and capacity.

How to charge LiFePo4 battery

The answer is simple. Please try to get the appropriate lifepo4 battery charger. To meet LFP battery pack charge principle CCCV. Its constant current is recommended 0.2C rate. Its constant voltage is recommended 3.65V*X(X equals series number.) When it charges by 0.2C rate to 3.65V*X, it will return to constant voltage & current to charge. Once its charging current becomes to 0.1C or 0.05C rate, it is full-charged. People also called it trickle charge. Except the core solution of charging, please also pay attention to following points: Make sure the charger work well Please check whether the LiFePo4
