This is interesting. I have 5,849 miles on my 4000li. Have owned it for 10 months. Initially, even though the batteries were dated 2008, my 4000li had a range of 47.6 miles on a full charge. Over the miles and months my range dropped, and at around 3800 miles my range was 32 miles. Well my charger burned out, and I received a new one this week. My range after 4 charges with the new charger is now up to 38 miles. I will see how she does over the next several charges, but I have a feeling that range will increase. Has anyone else ever seen this???? (20 Thundersky 40ah cells)

Anyone???? They recommend that if your range has decreased, before replacing the batteries you should replace the charger. That is a far less expensive fix, and it has certainly affected my cycle so far. Anyone Else????
I would suggest before replacing anything, get better instrumentation
A cycle analyst will make it pretty obvious if the charger is fully charging the battery, and tell you if the battery doesn't have the capacity it should have....
Guessing what is wrong and then replacing parts is fairly expensive, if not wasteful...

Does the 4000li have a controller port for direct connect to the cycle analyst?
I certaintly doubt it. But hooking up a cycle analyst is easy. You just need to put in a big shunt inline with the negative lead.

I couldn't agree more Matt!
When I get to the other side of town (about 27km) my "fuel gauge" sometimes reads 4/10 bars and I've be very scared I wouldn't make it back home. But the Cycle analyst reads "19.5Ah consumed" so I KNOW I have 30.5Ah left. Plus the "fuel gauge" flashes 2 bars when I use 30Ah. With the cycle analyst I can ride accordingly. If I know I am running low on power I can keep my power below 4000w instead of 8400w. There's no better feeling than cruising at 70km/h using just 1800w! I would be lost without my Cycle Analyst. I feel it is THE MOST IMPORTANT tool you can have on ANY electric vehicle.
