I made some big changes to get the sharp bends out of my chain. I changed out the battery with a lithium version and was able to mount on the left side. I also had to cut a notch out of a support tube for chain clearance. Now I have two idlers instead of three and a much smoother flow of the chain. I couldn't help but include a picture of the battery management LEDs on the new battery. There is on LED for each cell to indicate a full charge.
