The group 41 battery or its clsoe cousins is not Vanagon specific. It is
used in many VWs and Audis. As battery manufacturers are consolidating many
of the European batteries are becoming harder to find.
Many folks tie into the chassis battery for charging a house battery. One
thing to note is that the chassis battery is fed by basically a number 10
wire from the alternator to the starter cable. This also carries the current
for most of the vehicle loads. The battery is not the normal source of power
when the engine is running, the alternator is. Thus, the wireing from the
alternator needs to be upgraded or the charge line should be sourced from
there. This also should be considered when looking for brighter lights and
other auxillary loads. VW even realized the problem when they strted wiring
the AC feed from the alternator.
If you are only looking for battery charging and support of reasonable
loads, a #8 from the alternator will work very well. If looking to support a
large inverter (1,000 watts +)consider a self resetting circuit breaker to
limit current surges and protect the alternator from extended overload.
I like to limit inverters on the stock alternator to 800 watts. At that
point, I would go with #6 from the alternator to te battery.
If you also want to use the house battery as a boost for starting, then a
minimum of #4 and the best connection will be at the starter lug. You also
need to beef up the wiring between the starter lug and alternator, #4 or #2.
