Magnus 950 SS scooter?

[Rodney Nairne]

JL is trying something there, the torque of the scooter bothers his elbow and or shoulder, as he has thrown newspapers millions of times and worn it out!

Are the metal plates mounted on the shroud supports standard or something that is being tested? What effect do they have on the scooter?

I had a question about the Magnus battery discharging; it does not "self discharge", but the motor speed control electronics do use a small amount of energy whenever they are plugged in. So unplug, and no discharge. If you look at the internal pic of the Magnus you can see an olive drab colored regtangular metal box; that's the electronic speed control unit. It's not part of the battery pack.

All batteries self-discharge, some just do it a lot faster than others. I'm guessing that they were seeing it go down faster than expected though from having the electronics still hooked up?

No, not at all. You might have to wait 12 months to see any appreciable self discharge on a lithium cell.

Lithium batteries have a really low self discharge rate, but then so do Genesis Lead acid batteries... NiMH stand out in requiring a lot of maintenance.

It's just something to keep in mind, you can't stage a Magnus scooter in the cave for 6 weeks and expect a full battery... for this application you would need a UV or N-19 (brushed motor) scooter with a lithium or lead acid pack.
