Wholesale lifepo4 battery LFP12.8V 50AH replace lead acid battery, the most popular lithium battery pack,LFP12.8V 50AH Lithium Iron Phosphate long life cycle Battery

Short Description:

Model No.: LFP12.8V50AH-50
Introduction:
LFP LFP12.8V50AH-50 lithium ion battery is the most popular model in the market
LFP LFP12.8V50AH-50 lifepo4 battery is Easy to installed, in the old recharge battery used of Lead Acid, GEL or AGM type batteries , if the total connect batteries not more than 4series , most of the application, the lithium battery could replace directly. The lithium battery have the same standard dimension of lead acid battery.
The LFP12.8V is lighter weight, it could only 30% lighter than SLA battery for each AH unit; it is higher cycle life and lower cycle cost than the Liquid battery.
