I have put about 7500 miles on my Suzuki SP200 and my batteries are getting tired. I had Sony VT 26650 cells in it run as 18S12P for approx 75 volts and 32AH. Reality was closer to 25AH. It has gotten to the point that I could not make the 8.5 mile commute to work at a safe speed. So time to upgrade. Hobby King was running a special no shipping sale in the US so jumped on 20 of the 5S 5000MaH 20C Turnigys http://www.hobbyking.com/hobbyking/stor ... duct=15008
Price to my door $827. These will be arranged 20S5P for 85 volts and 25AH.
Here is a pic of the old Sony cells 55 Lbs
