Programing SW102 display for 14S battery.

[yabert]

I would like to change the SOC display of my SW102 (mini LCD display) on my cargo bike.
At the moment it's programmed for 48V battery and only show 100% SOC up to the moment my 14S battery is near empty.
So, how to change the SOC range from 43-52V to a more realistic 14S battery voltage (46-58V)?
What are the steps to do this and the parts need (programming cable, etc)?
Thanks

Ummm! Any idea?
I've hard time to believe than nobody know how to program this SW102 display.

If you can't find a programming method, you could insert a series of diodes into the battery positive line into the display that equal a voltage drop of 4.2v (one cell's worth at full voltage), or whatever voltage you prefer (I'd probably go with the average of 3.7v or so, which at about 0.7v per diode for a typical type is about 5 diodes in series. Even the tiny 1n4148 could be used, so it would fit in some heatshrink inside an extension for the display cabling.

It won't make the display accurate, but it will help with the main problem.

Not a bad idea. Worth the try.
Thanks amberwolf.
