12 cells in a module, full automatic assembly line, high quality.
This battery module is designed for EV, made of 3.7V 32Ah(37Ah) NMC battery cell, which material is widely-used in China EV market and our overseas market.
This material is featured as high energy density, light weight and small size.
Back to the module, we put in 12 cells in a module with the same size in order to realize the multiple capacity and voltage requirement from customer and to realize automatic assembly process.

Do the batteries have a warranty?
§ Yes, currently 3 years; extended warranties are also available.
How long do the batteries last?
§ 10 years / 200,000 KM (124,275 miles) [calculated based on 100km battery pack]
§ 2000 charges & discharges at 100%.
§ This means approximately 10 years of normal use 200,000 KM. (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 power
