Exciting news — we are shipping the new "battery" version of our large capacity MH900e endurance racing tank.
The (pdf file) attached to this document is a supplement to accompany the existing instructions for installing the original version of the tank. The only additional parts required are a longer starter cable, M6 screw, and a spacer. There are no permanent alterations required for this REV-B "battery" tank to be installed and work. More info, too, on this older news article.
