CNC-machined battery pack backstop for XRAY X1219 produced from premium-grade graphite product. The battery backstop and back link brace permit a wider array of battery pack placement adjustment. The brace includes two holes into which the adjustable battery pack backstop is inserted. The battery pack backstop has 4 positions which allow the batteries to be moved more forward. The distance between each place is 2mm, therefore in total the battery pack is moved up to 6mm more ahead. Frontward-placed battery pack makes the vehicle easier to drive, reduces wheel lift in corners, and makes the automobile more predictable over bumps. Rearward-placed battery makes the vehicle more aggressive, increases cornering rate, but makes the vehicle more difficult to drive.
