(124,275 miles)§ Normal use is defined as 20,000km/year. (12,500 miles/year)Do you use Lead Acid Batteries?NO WE DO NOT! Our reasons:§ Lead Acid Batteries do not allow as many charge &discharge cycles as advanced lithium batteries§ Lead Acid batteries degrade after 300 charge cycles in an electric car until they expire, approximately 1.5 -2 years of driving§ Not cost effective to change your battery pack every two years§ Lead Acid is HEAVY, and reduces your range, doesn't supply continuous powerCustomer FeedbackWe are happy with your battery quality.
