Turning left, at zero speed, uses 100A per motor to turn. Every time you do it.
Driving at max speed uses maybe 10A or 15A or so.
Driving up a hill, anything up to 100A or greater..
Grass? Doubles everything.
Solid tyres, add a few amps.
Tired less efficient motors, maybe adds 10% wasted energy
Nose heavy chair, eats power on turns.
I can kill a set of lead batteries leaf blowing the crap off my drive and garden. In say 1 hour. And get roll back and no power3 or 4 times over!
Same chair will go 3 hours at 6 mph non stop and do 18 miles. In a straight line. But not if I waste a load of power getting ready in a morning around the house. That halves it.

A 4-digit voltmeter is easy but good and safe enough, fit it before your next 'draining test'.

4mph HD with 4 pole. For high torque bariatric use.
4mph 2 pole because its cheap slow gives adequate torque.
6mph 2 pole because its cheap! And useless...
6mph 4 pole because it works properly, and can make use of a bigger amp controller.
8mph 4 pole - same as above, but less torque and control, high drain, more speed, otherwise the same as above. OK on flat ground, and are skinny...
