Max amps pull depends of course on the motor and wiring resistance.

It came with 6.5 mph 4 pole motors, Group 24 MK batteries, tilt, swing away joystick, and standard rear suspension out of the factory. I paid an extra $85.00 for 9" front casters when it was ordered.
I have owned both a Quickie S-646 and a S-646SE in the past. Unlike the older models, the ANTI-TIPPERS COME RAISED 1" right out of the factory. They are not in constant contact with the ground. The speed and torque are more than adequate for my needs. If I am on #5 speed setting, it will Whip from side to side like a soccer chair if I desire.
With the 9" casters the ride is smoother than my Invacare 3G Arrow with it's 8" suspension forks and almost as fast. This is a great outdoor chair that qualifies as an indoor type for insurance purposes. This is a very good choice if you want both indoor and outdoor performance. I am a demanding user, and drive it hard every day. I am very pleased with this chair.

It's as close to a BM as I'll ever get. They let me dive it outside and on a grassy but modest hill, then switch it up to the full 6.5 mph, which seemed plenty fast compared to my Invacare 4.5mph model. So now the phase 2 paperwork starts. It took a month just to get the seating appointment.
rep said he could bring his programming box next week)

The Power Tilt was a $ 6,187.50 addition
