    Default Relocating batteries & Mounting amps

    So David, I guess me overall question is what is the worst that can happen by relocating one or both stereo batteries to the other side of the boat?

    Certainly nothing catastrophic will happen. And it's impossible to numerically qualify exactly what would be compromised in the way of performance or longevity. Doubling your cable distance adds resistance and that is counter-productive at every level. You can offset the cable distance with a larger gauge cable. That alone makes it an inefficient move from a standpoint of cost-effectiveness. Real copper heavy gauge cables are brutally expensive unless you are using junk wire on the cheap with reduced copper content at half the weight. While it may be a fraction of the cost, it is also a multiple of the resistance.
    I would not separate two batteries on the same bank by any distance since the ideal scenario is matched batteries in every aspect. I would want them to start out identical and age identically. I would place the charger closest to the deeply cycled bank. If I had an inequity I would place it between the two banks but not between two batteries of the same bank.

    I got the 20 plus. I'm glad too because I think I am adding a second house battery.

    Just pulled them from the boat. I only plugged the charger in a couple of times over the last five months. Thought I would check their condition. Looks like I can leave them in year round with no worries.

    The self-discharge on AGMs is less than on a flooded battery, which is several percent per month. And AGMs rest at about a volt higher to start with. Barely more than a half volt drop over two months is very good.
    When checking a battery, make sure to let the charging voltage, whether from an alternator or shore charger, completely dissipate for a true reading.
    Having an isolating battery switch helps eliminate any potential for a parasitic drain. And make sure to get the HU memory off line while in long term storage.
    With a big audio system and a large battery bank, you still need an AC shore charger for full restoration after a weekend outting. An alternator alone usually won't get it done, especially if you spend any time at rest.
