Specifications
lifepo4 12v 20ah
100% brand new and high quality
Longer cycle life 2000 cycles
Lifepo4 battery will replace SLA
-
Our customers can buy 4 pieces 12V20Ah battery pack with bms from us and wired in series to make 48V20Ah battery pack
The most remarkable advantages of large format lithium iron phosphate (LiFePO4) compare with SLA are listed as below:
A. The cycle life of LiFePO4 is more than 1000 times.but the SLA is 300 times.
B. The Gravimetric energy density (Wh/kg) and volumetric energy density (Wh/L) of LiFePO4 is about 3-4 times of SLA.
C. But for the weight and Size comparison for the same capacity,the LiFePO4 is just 1/3 of SLA.
There are some other different specifications which suit for E-bicycles, E-tricycles, E-scooters, E-motorcycles, golf cars, commute cars, pedicabs, E-boats and etc.
