This is one of the newer ones, Not the PVC. Comes with a smart charger. I don't have a battery tester but ran it for about 50 min without an issue. I also have a tube that been cut for a short body. I have the hardware and batteries that were going to fit into the short body but I am not sure on those batteries. I had not cleaned the edges of the short body. This was a WKPP scooter. I paid approx 1500 for it. I have kept it on a smart charger on a regular basis. It is large and heavy. It is not as fast as an SS but probably would be faster with newer batteries and be closer in speed.
