The FETs (P60NF06) are rated for 60v, 60A (not bad)
the freewheel diodes (STPS20S) are rated for 100v, so this controller won't have any problem with up to 48v in the output stage.
There could be issues with the voltage regulator, so one way around that is to bypass the keyswitch input to a tap on the battery. Normally the key switch (on/off switch) takes power from the battery + and switches it to the control logic voltage regulator. Instead of connecting it to 36 or 48v, you can feed the keyswitch from the 24v tap between batteries. This way the low voltage cutout will still function and there won't be a problem with the voltage regulator input rating.
Some controllers use a regulator that would be fine with the higher voltage, but if you're not sure, I would avoid using the normal hookup.
