2 in series =24v will blow car elecrics
2 in parralel = 2 x ah that will strain and posibly blow the alternator
ad to that the need for large cable running to the boot and its all a bit point less
get a cheep spliy charger it uses nice small cable that is eazily run . and it auto detects wbdn main batter if full and switches charge to secondary , no chancs of ever running main battery flat

the problem you have if not using a split charger is your 60A altanator trying to charge a 110A+60A battery
170A is to much for it
add to that the stronger of the 2 batteries will always try to back feed so it will not get to its full capacity and may even damage the smaller one by overcharging it

60Ah split charging system,ok why is this please?
If I want to charge a 110Ah don't I need one that's rated for that ?

Cheers

Question,would the standard alternator be good enough for this task ?

Cheers folks

What's the reason you want a split charge system ?
If it's just for winching there's no real reason for it. Just parallel connect the batteries.

The reason is I use amateur radio equipment and quite a powerful linear amp.

The radio draws around 10 amps and the linear around 45 ish..
