12v from 24volt, low tech way

Perhaps the simplest way to get 12 volts on board without upsetting the
charging of the original dual battery system is to add a third battery of
size and capacity for the individuals needs and just let it charge from the
24 volt system.

You would need a charger, which in effect would be a 24 v to charging
voltage converter. Since the third battery acts as a huge filter, that
converter can be much simpler than a full blown DC to DC converter and of a
lot lower capacity.

I think this would be a lot easier than adding a separate
alternator/regulator and wiring etc.

Let me know if I'm missing something, it happens.

Regards,
Bjorn
