Its all safe. Even if you set it to 30V you will only go a tiny tiny bit faster. maybe 1 or 2 % because as you drive with a FULL battery the voltage drops to say 22 to 24V as you use the chair. By setting it higher you lose a tiny bit of headroom, above that 22 volts. Does this matter?

As you drive at full speed, and then decide to correct your direction or to turn, the wheelchair needs to add MORE volts to 1 motor. And less volts to the other.
If there is no extra voltage available, then it can only reduce volts to one motor. It cannot increase it to the other. The result is that the chair slows slightly as you steer, and steering - esp uphill, and especially when the battery is not full, is that steering feels weak and unresponsive. Set it to 22.5 if you have good batteries. You will gain a tiny bit of speed on a level or downhill road. But it will be a little less responsive and slow when you steer at max speed.

Only on the display. You can set it to anything you want. It wont be true, but will look good!

The Wheelchair Maximum Rated Speed is what gets displayed at FULL STICK. Even when you are slowed by a hill, or stalled against a wall and not moving at all. It depends only on the stick position - not actual speed so it isnt accurate. Fit bigger tyres? You will go faster. Fit faster motors? You will go faster. Unless you correct it here it will still read exactly the same!

The SCALE that this sits on in the display can be the same number, say 8mph? Or more. Your choice. 2 seperate settings. This is Maximum Rated Speed

Non of them have any affect on the actual wheelchair speed. That is set by volts globally, and by the speed settings in each profile. For that you need a long straight road and a good GPS app on your phone. Then set the wheelchair speed the same.

You might also look and read HERE carefully!!! viewtopic.php?f=2&t=8035

You cannot set up everything is a day. You can if you know what you are doing get it 80% as good as can be in a full day. Fully sorted takes me months. Small changes here and there as I use it. But you really need a dongle, even dealer, and use that with the OEM software for ourself. Theres too much to test or think about in a day.

The 3 in yellow:
Maximum Rated Speed
Max Display Speed
Max motor volts. (limited to actual battery volts available)

You answered as I was editing! See above, re read!

More importantly you might read this page or so.
You might also look and read HERE carefully!!! viewtopic.php?f=2&t=8035

IF you have a Gyro, or stability module, make a new profile with my settings here and test. As long as you DISABLE the gyro in that profile and you are not driving a front drive chair.

What speed is displayed on your guage. I am baffled. You have choosen KM and set speed faster than the display. Unless I got it backwards your chair will run off the end of the speedometer?

What chair is it?

Compensation sounds correct.

Forget turn settings a myra isnt a wheelchair it steers completely differently so dont use the settings on the link!

And you can set 24.0V as voltage as it doesent use tank steer to change direction. It behaves and has the layout of a scooter. At least if its the front drive myra chair I am thinking of.

Motor watts tells us nothing useful. If 2 pole then its definitely too low. Are they 4 pole? If so motor compensation may be a little low. If you increase it do it is very small steps. Like 5mOhm at a time. Dont exceed 50...

If it feels jumpy reduce it. If it feels more positive and responsive and not jumpy keep increasing it is small steps. Too high? You get an unstoppable runaway. :cussing

If you want a bit more. And if you want 60 to 70 miles of real world range, and a battery that lasts a decade, you need to go lithium!

Well it may be but you dont have to use it. Or charge once a week... This ensures an easy life and a long battery life. Its not only about max range. A small lithium pack is worked hard. They dont like high discharge rates per Ah, or deep discharges. So bigger is better always. And it fits the same space. And you will still save 50% of the leads weight. So all good!

No your charger cant charge it. We are all using the cell balancing 40A PL8v2 hobby charger. Currently out of stock. It balances the 8 cells that you will need to make a complete battery. Graphs and allows full PC control and can measure capacity etc.

These are 176Ah, 180Ah, 200Ah, 200 plus now as well. All from china, and all take a long while shipping. And theres many suppliers of cells. Such as:

For e.g. https://www.rj-lithium.com/sale-1153865 ... orage.html or aliexpress, and many more.

Quick search finds these for e.g. https://www.aliexpress.com/item/3297625 ... b201603_55

Note I am not recommending this seller, just an example. These will fit in the space a set of group 24 batts come from. For a 24V (actually around 25.6V in use) you need EIGHT cells connected in series. Many of us have been doing the lithium thing for a decade. And still going strong! So it works out cheaper by far. Even ignoring the rediculous range. Remember that a 70Ah lead battery only gives you typically 35Ah before you stop. And gets worse over a year. This gives the full 200Ah. So 5 to 6x the range. And an easy life, so many years. And much faster charging!

Some chairs have ENCODERS fitted. So the control system knows the exact position of a wheel. Those setting are for configuring the encoder module to match the chair. It doesent apply to your chair unless it has encoders. 99% do not. Its a speciality thing. And no that wont change the speed.
