I disagree. Two 12v batteries in series to make a 24v battery will self-level
with respect to charge.

They will self level even if one is tapped to run a VHF. No harm will come
to either battery. Voltage can be likened to pressure.

I hope this helps.

bullcrap.... Better to leave the Blackgang stuff to the engineers that
know what they are talking about......

I'm an electrician. Don't insult me with this engineer crap. I know how
batteries work and I know circuits - particularly DC circuits.

You idiots are only correct provided there is no circuit to which the
two 12v batteries in series are connected. In any yacht I've ever
been on the batteries are part of a circuit of there would be no
use to have them aboard other than as ballast.

In Nigel's case, tapping off one of two batteries connected in series in
a circuit to run his VHF will not cause only the tapped battery to discharge
as the voltage in the circuit will be lowered and not just the voltage
in the tapped battery.

Only if the two batteries were disconnected from the circuit would
the tapped battery discharge more than the untapped battery.

C'mon, folks, it doesn't take a rocket scientist to figure something
this basic out.
