Get yourself or beg/borrow (I don't advise steal) ... a voltmeter. Better
yet, get a knowledgeable person to check it out for you. Yes, could be you
have the 2 12V's connected in series to add up to 24V ... or not ... or
maybe they are connected in parallel for 12V (trolling motors can be 12 or
24 or more).

I have a Larson 186 SF. It has three batteries. One is a 24 volt
battery for carnking. The other two are Continental Super Stalker
deep cycle trolling batteries (T27-165). How do I tell if they are 24
volt or 12 volt? I need to charge them, I think they might be two 12
volt batteries in a 24 volt system but I am not sure so I need to know
if I can use my 12 volt charger on them? I have an adapter that plugs
into the outlet for the trolling motor to plug into that you connect
your charger to so that it charges both of those batteries but I do
not want to use the wrong charger.

Thanks,

Jeremy
