U1 Battery Lithium Iron Phosphate 12V 35AH 480CCA Starting Battery for Lawn Mower

12V 35AH Lithium Ion leisure Battery is a high-performing deep cycle battery built on patented Lithium Iron Phosphate (LiFePO₄) chemistry. The u1 battery 12V 35AH Lithium Ion Battery features a built-in automatic battery management system (BMS) that keeps the cell balancing running at peak performance while preventing overheating, overcharging, and maximizing cell cycle life.


The B-LFP12-35 is a lithium iron phosphate (LiFePO4) battery with more power, less weight, and up to 10x longer life than its lead-acid counterparts Lithium is the logical choice for applications that will exhaust the batteries or run in extreme weather. BSLBATT lithium batteries provide more energy for high consumption than traditional lead-acid batteries. Lead-acid batteries also need to be maintained. If they are not maintained properly, their life span is shortened. Because lithium batteries require no active maintenance, a one-time purchase guarantees leisure better lifetime value.
