Lithium-ion batteries by AntiGravity 

Want a lightweight battery, and we mean seriously lightweight, for your track car but hate the idea of drilling into your chassis to mount some additional mount to hold the undersized battery in place? Put off a lithium battery for fear of damaging it by forgetting to leave it on a charger or leaving something in your car on drawing the power away? What about the high price, exceeding $2,500 in some cases for a lithium battery? AntiGravity has solved all of those concerns! We only use AntiGravity batteries in all of our cars and clients cars, even street cars! Here's why!

• Smart Battery Management System (BMS) protects from over and undercharging and puts the battery to "Sleep" before it damages any of the internals  
• Forget the charger for the winter? No problem! Internal jump starter with a remote so you won't be stranded again!*
• Check the battery health from an app on your phone
• Factory fit, complete drop in option. Just remove your old battery and install your new Lithium-Ion AntiGravity battery!
• Fraction of the OEM options price
• Up to 3x the Cranking Amps of similar sized lead/acid battery. Better Starting and higher voltage at start-up.
• We have found these to last up to twice as long as lead acid batteries
