How have those of you who run a 24v C5 got around the 12v supply for the lights, indicators etc?

Ok, so you would need a 24v battery one side for the motor and another battery - 12v - for the electrics.

What if you were using 2 12v batteries to get 24v - then how would you be able to send 12v to the electrics?

Al you have to do is to run - + leads from one battery to the lighting circuit and the horn etc .

But if 2 batteries are linked how does that just send 12v to the lighting circuit?

Oh thats good. I like the idea.

Car or leisure battery too large for boot maybe? What kind of battery would fit in the boot?

Answer to post #5.

This info is only applicable if you are not using the C5 control box and pod.

You have battery 1 and battery 2, call the negative pole on battery 1 "A" and the positive "B", negative one battery 2 "C" and positive "D". So for 24 volt "B" is connected to "C"

To have a 24v operation, connect the minus to "A" and plus to "D". To simultaneously have a 12v supply connect to "A" and "B", or "C" and "D". Charging should be 12v to "A" and "B" first, when charged, then "C" and "D".

For a separate 12v battery supply go for a sealed e-scooter/e-bike(gel) battery 9ah or 7ah, and not one for a motorcycle, as these are wet and can leak.

I recommend that you convert to LED lighting and indicators, flasher unit, etc, as these use far less current than the original C5 gear, thereby a 12v block can be used.
