Well cables screw up. So having a long spare means whichever one does, you can fix it or get going again if out. So at that price good to have.
Also that means you can program your 120 power module ready with your file from the chair. You need a joysstick, and a PM and a bus cable. And you need to add 20 to 24V to the two centre pons THE CORRECT WAY AROUND! Plus to plus. Minus to minus. Dont get it backwards there be smoke!
Then program it. Ignore all the errors because you have no seating, motors etc connected. Just send it your preset.
Now, when you break down, you can just swap the power module and it will go. Be suse your girls or a capable person knows which cupboard you stashed these in. And you are all set for a rescue.
