We do not offer a lithium battery powered solution for the Action Trackchair for various reasons. We understand there are many pros to lithium including power, recharge time, and battery life. We installed all Action Trackchair with two (2) AGM (Absorbed Glass Mat) batteries for many reasons including: cost-efficiencies, maintanence, performance in wide-ranges of temperatures including cold environments and availabilty.
Offering a lithium powered battery solution may be available in the future.
