Don’t know if he has any left.
FS: DeltaQ 72V chargers
I used two 44 volt packs in mine.
Run 15 miles on hills between charges.
Try it without reprogramming first.
Can supply programming USB cables.
I have a speed spoof MM. and a voltage spoof.
Use parallel 88v for more range.
Recommend parallel each cell or A/B switch.
