secondary battery charger

[rufus99]

I have a cruiser fitted with a Sterling 20a charger which charges 2 x seperate engine batteries an 1 x bank of 4 domestic batteries.
I use a Honda generator to charge batteries when moored, but the present charger takes an age to do the job, now the question:-
Would it be feasable to fit a 2nd automatic charger to the domestic bank only to bost the charge rate without risk of damage or should I stop being a tight fisted git and invest £400 ish in a bigger chrarger?

As you may have noticed, electrickery (the type that makes your hair stand up) is not my stong point!

Thanks

how do you know that the chrger takes an age? And is it taking an age a real problem? Slower charging is generaly better.

Thanks TCM, the battery state is monitored via the voltmeter whilst charging and so I know charging is slow.
I prefer to use the generator as little as possible so as not to create noise for longer as necessary.
