T&T: 24V starter, 12V house bank - Ugh!

[Cole Crockett]

My last boat had a 24 volt LectraSan, while the rest of the boat was 12 
Volt, if you bank two 12 volt batteries to make the 24 volts all you 
need is a charger that can do both 12 volt batteries at one time, in 
other words, you get either a two bank 12 volt charger or 2 separate 12 
volt chargers, the one mine had was designed to keep more than one 12 
volt battery on a bass boat charged up. Someone else on the list may 
know how to wire the 12 volt alternator to charge both batteries while 
underway? I'm sure it's no big deal. So, if you have the space, you only 
need to set up a bank of two 12 volt batteries dedicated to starting the 
engine, since they should never get drained hard, you don't even need 
deep cycle batteries.
