Hello I am new to this EV world just bought my first EV vehicle a 2014 Chevy Spark and I am looking to modify it. I love the car but the battery range is just not that great. Manufacturer says that it can have a range of 82 miles but being 2014 the most I can charge it is 67 miles. So I am hoping that I can replace the stock GM batteries with the Tesla 18650 batteries? And hopefully I can extent my range of the vehicle? Would anyone have any knowledge of working on the spark EV battery pack, and if this can be done? Any help would be great.
