Bob, on Pegasus I have a 4d (house 1) under the port q-berth, a pair of 6volts under the companion way (house 2) and a pair of group 24 for starting and windlass on the shelf to port of the engine. This keeps all heavy battery cables (except windlass) in short runs, lessens the voltage

A couple good points were made here. At the present moment my second (44-lb) anchor and rode are not on the bow--once I add this, it will help with weight distribution. The other benefit of moving batteries around would be space gains in the starboard cockpit locker where I now have two batter

If it will be very rare to ever need a v-berth house battery for engine starting, how about, if the need were to arise, disconnect one of the v-berth batteries, take it aft, and use some jumper cables to get the engine started. Bob M Ox 33-1 Jax. FL ___

Technically vapors are an issue. All battery types - wet/sealed/gel/AGM - are subject to ABYC venting guidelines. There are some solutions - venting the battery enclosure or having vented caps for wet cell directed overboard somehow. Ed On Nov 19, 2015 12:50 PM, "Robert Boyer via CnC-List" wrote:

I DO use AGMs--so, vapors are not an issue. I have some space just forward of the mast under the settee but close to the boat's centerline that might work for battery storage--I have to check out the dimensions but this would remove weight aft and add it close to the center of gravity. Bob Bo

Bob — I would consider sizing the wiring aft from the forward batteries to allow at least 100 amps, with a maximum 10% voltage drop. This would require at least 4AWG cabling from under the v-berth to the electrical panel aft; better would be 2AWG, which would allow you to pull 30 amps with a 3%

Bob, as you said, the current from the house batteries should never be high, so the wires should not be an issue. However, if you calculate your load at 30 A and select appropriate gauge of the wire (for distance), make sure that you install an appropriate fuse (probably not larger than 50 A) (
