Yes, sure will.

That's the beauty and elegance of the way the original Segway machines were made.
The charging system is software controlled, so that NiMH, Li-ion or yet to be announced batteries could be charged ( all that was needed was a software update ).

There was a really good team on that project !

If i chip in?

I have two xt machines and they both work fine with lithium or nimh batteries, they also charge correctly as the charging process is controlled by the battery nit the segway, as far as charging is concerned the segway us just an on demand power source.

The only thing that may happen is under extreme load the nimh will drop more voltage due to a slightly higher internal resistance....but honestly I've never noticed and I ride mine hard.

Awesome info! I just placed an order for a pair of working nimh batteries for a hundred bucks. Can’t wait for them to arrive so I can try out my XT!

What kind of range do you get with the nimh packs?

Thanks, Mike

The XT lives! Thanks all for the help!

I have taken apart everything including the base cover off and checked every connection I can get to. I have been charging the batteries constantly and am thinking they are finally getting balanced out. I unplugged it earlier to drag into the house as we had to leave. On the way in it got jarred around pretty good potentially knocking a stuck sensor loose....maybe. I decided to try the key again and it made a slightly different noise. I tapped the key several times, it made weird noises and the screen went to orange/yellow. I pushed the button and it went to balance mode! The batteries are weak as I get errors and stick shake when I make it turn hard that points voltage sag. But it works!

Now I know it is worth investing in li ion packs for it. Now I want another for my wife. I think an I180 with a bit more aggressive tires will be perfect for her.

Thanks again All, Mike
