Hi Guys. I have a 52 volt battery and a 48 volt motor. ..... does anyone know of any better solutions?

If you don't get OSF working as you want you can flash modified stock FW too.
In that case you can use the 52V battery.

Hi Guys. I reflashed back to the modified stock firmware choosing the 52v version to match my battery. It seemed to take ok, but I still cannot get the motor to work. I reconnected the original stock VLCD-5 screen (which is fixed on 48v I think).
1. When I turn the screen on now, pedals vertical, it seems to initialise within a couple of seconds. I understand this switching on should take some time??
2. The battery indicator shows one bar even though the battery is fully charged at 57volts. This is not correct.
3. I now have a motor with modified stock FW at 52 volts and a 48v original FW display. Is this correct, or what display should I use? I don't see a way to change screen voltage to match.
Flashing the FW onto the controller seems to work ok. Does this mean that the controller is working properly? Is there any way of checking the controller? What symptoms would a faulty controller give if I needed to replace it? If I buy a new 48 volt controller, I am still stuck with the mismatched 52 volt battery.
I bought a 52 volt battery and 48 volt motor intending to just use the open software. I have completely failed to make the OSF work, and I'm looking at ways to try and get the motor to work in any configuration. I'm tempted to buy a new controller, but it does seem to accept the flashing, so is the controller likely to be the fault?
I read of plenty people buying motors of a particular voltage to match the old battery they already own, which is not always the best decision process. Has anybody used a buck converter or step controller to match battery to motor? A 30amp one at £28 should do the trick, but the first issue I see is that the motor controller cannot look after the battery on low voltage cut off because it only sees converter voltage.
A lot of questions but I am completely stuck on what to try next. I have already tried every configuration of swapping 8 pin leads, tx and Rx, reflashing everything, rechecking wire colours and connections. Everything was triple checked, so nothing should have been blown.
As no instructions came with the motor, I'm assuming that I put pedals vertical, switch everything on, wait for the screen to show, key in an assist level and ride away!
Many thanks in advance.
