Electric fat bike conversion kit

Brand new, sealed in box. Unopened. Bought from on EU supplier, with full warranty 26" fat bike rear wheel, 48V kit, nominal 1000W. But these kits can run 52V, 60V, 72V, 96V and you can get 3000-4000W out of them Everything included, including LCD colour screen, controller, throttle, pedal assist sensor, etc. But NO battery in this kit. I was going to use Lidl power tool batteries, you can easily pick these up for about €10 each on adverts. You would need 2 or 4 at least of these, for a 72V nominal battery (84V fully charged) I'm in Lucan
