3.2V50Ah LiFePO4 cylindrical Battery Cell DYI battery pack used in marine
LiFePO4 batteries are a type of lithium battery built from lithium iron phosphate.
LiFePO4 battery cycle performance is excellent, energy battery cycle life can be up to 3000 ~ 4000 times, rate battery cycle can even reach tens of thousands of times.
LiFePO4 raw material resources are relatively rich, which greatly reduces the cost of materials and batteries, and because iron and phosphorus elements are environmentally friendly, lithium iron phosphate materials and batteries are pollution-free.
