Recently purchased a Pearson 33, with a house bank of 4 6V golf cart batteries wired in parallel and series for one large bank. The battery compartment was designed for 2 Group 27 or 31's, so the 4 6V golf cart batteries fit, but barely. Surveyor recommends putting all batteries in CG approved battery box. Problem is that the battery compartment is about 12" high and all battery boxes I can locate for golf cart batteries are higher than that. There is a top on the wooden battery box and they are secure, but would like to put them in a battery box. Those of you that have swapped house batteries for 6V golf batteries, how have you addressed finding an off-the-shelf battery box that fits or other solution to safely secure the golf cart batteries ?
