The Link 2000 probably has nothing to do with overcharging your batteries, since it is a charge monitor, not a charge controller, unless you have the Link 2000R, which has an external regulator for your alternator. The Freedom 25 is probably configured wrong. Yes, you can set the Freedom 25 from the Link 2000.

How many batteries did you have in your house bank? The problem may be the size of the charger you're using. The Freedom 25 is an 130 Amp charger, and unless you've got four or more 6V golf-cart sized batteries, the size of the charger may be the problem. BTW, if you're going to go with Trojan T105 type wet-cell batteries, you'll need at least six for the charger to be about the right size. A battery charger shouldn't be more than about 20% of the battery bank's capacity for wet cells. Six T-105 batteries will be 675 amp hours of battery capacity, 20% of that is 135 amps.

As Steve has pointed out AGMs are probably a better choice if you neglect basic battery maintenance, but the Trojans will work very well if you care for them properly. More batteries die of neglect and abuse than ever die of old age.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
