Short video of a Riley XR3 XSO EV powered by only half of its full complement of LiFeTech batteries (turn up the sound on the video!)-

Seen that before while looking at trike videos. Being he is in America they will probably let him register it.

I have to question his math though. "The battery pack will double in size. This will double the acceleration and range."

If he said this will double the acceleration or range I might be inclined to agree, but not both as "and" implies.

Edit: If it was true then he should have put the second half in first Image

I agree. It might increase his range but not nearly double. Considering it has no bodywork, glass etc - so is really light - extra batteries will substantially increase his weight so RR will increase.

Acceleration wise. Low down RPM will not benefit from more cells (unless the lifebatts are sagging badly), and extra weight again will diminish returns from extra voltage being available that would be boosting high RPM torque.
Maybe someone misquoted him...

I agree with you Johny. Anyway it will be interesting to see how it goes when the body is finished and all the batteries have been fitted.

Wouldn't mind getting a good look at the hydraulic system, it looks pretty cool, not sure how functional it would be over leaving the height set, but still looks pretty trick all the same.
