Antigravity Batteries feature RE-START in their lightweight lithium-ion motorcycles batteries so you'll never get stranded. Simply press the RE-START button to activate the built-in jump starting, start the bike and ride off. Anti-Gravity motorcycles batteries use prismatic/pouch cells and LifePo4 (Lithium Iron Phosphate) technology. Every Anti-Gravity motorcycle battery uses a battery management system (BMS) that protects the battery inside, charging system of the bike and to prevent thermal runaway. They charges and work with all 12V motorcycle systems, provided the stock system is charging correctly. A Lifepo4 charger is required to charge and tender the battery when not in use.
