everything looks good except the battery tray, there is nothing to keep te battery from shifting into the spur, here is my setup but as u found using the 62 spur doent let u get many batt tray placement options, i bought a new era batt tray and modified it for my 5s 5000mah zippy pack, bolted it in for places to the frame for rock solid mount and its nice as the tray has walls up the side to keep the battery in place from side shifting as velcro has give hope this helps
