Relocating batteries

Hey all,

While I am undergoing my refit, I am debating about moving my batteries from under the cockpit sole(behind the engine) as they are quite cumbersome to get to.

Where do you all store yours? I was thinking about moving mine to under the settee on the port side as the starboard side has a water tank.

I was also thinking I could move them under the aft cabin berth(where the starter battery is) and also the extra water tank(which is unused due to a leak) and also a diesel tank. If I moved the batteries here, I would remove the water tank and install a new one where the port settee is(or maybe just a water maker).

Either way, I'd like to see what others have done. I current have AGM lifeline 6V batteries (4) but they are due for replacement. I am not completely closed to trojan 105, but would prefer AGM as I have had an 8D burst and cause havoc.

What say yee?

Re: Relocating batteries

I’d start by finding a tape measure. Then look at cable routing. Venting isn’t really a consideration but some folks are paranoid about that. My biggest issue would be ease of access.

Re: Relocating batteries

Weight distribution and list is something you should also consider. Good luck.

Re: Relocating batteries

Well, I know it's a heated topic but about two years ago we upgraded our bank to 5 LiFePo 100Ah batteries from Battleborn. Tons of power, zero maintenance, deeper discharges, and 70% lighter than our old lead acids. At 30lbs. each you could literally mount them up on deck and not have to worry about "weight distribution"....

Re: Relocating batteries

I was definitely thinking about weight distribution as a concern. If i mounted below aft cabin berth, I could just not have a water tank on that side and in theory, be roughly equal. This should give me about 40 gallons of water on the starboard tank. That in turn would force me to install a water maker prior to setting off.

Mines a 42ft mono thats already quite heavy. I dont think adding the bank to one side would drastically affect my performance. Moving the batteries to under the berth would be about a 8-10ft span, vs moving to under the settee would be atleast a 20ft span from where it currently is located. Would significantly reduce my 3/0 cable run to the bow for the windlass for sure.

I am not too worried about venting IF i go with AGM. FLA i'd be a little more cautious on.

As for LiFePo, I am not sure I can afford it as I'd have to upgrade my Magnum Interver/Charger. I'd rather go with Firefly AGM's as it gets me close to LiFePo performance and aren't terribly heavy(71lbs @ 110amps).

I'll have to evaluate cable runs from shore power plug to where inverter/charger would be and where my AC panel should be located. Maybe will be able to moev my DC/AC system to the nav station from under the companionway.
