I notice there is a thread relating to batteries, so thought it worth starting another regarding some of the issues/modifications with our SO33i performance version with Premier pack.
Noodle was commissioned last year. In standard form the SO33i is supplied with a single 70Ah boat battery and a single 70Ah engine battery. The premier pack includes and extra 70Ah boat battery.
Batteries are mounted in two compartments under the rear berth. The engine battery and one boat battery were mounted side by side in the starboard battery compartment (380mm x 280mm) close to the isolation switches and labelled “domestic”! The second boat battery was mounted in the port side battery compartment (410mm x 190mm) and labelled “engine battery”! All batteries were Exide EB705 starter batteries. Given lack of space and the amount of battery cables tucked in and tie wrapped together it was not possible to easily determine the arrangement - some confusion at first when using a multimeter to check the batteries.

I was not happy with the performance of the boat batteries so searched around to seek the best option (i.e. I vacillated). Fitting additional battery compartment in the outside (port) locker was considered, but ruled out on basis of additional work, loss of space and weight distribution. Lack of height within the compartments (260mm) ruled out arrangements using 6v batteries.
In the mean time, on one occasion, we forgot to isolate the batteries (although everything was switched off at the panel). Returning to the boat after a short period of time (a week), the boat batteries were flat (circa 2v), so a solution was needed immediately.
Varta AGM batteries were chosen on the basis that they would fit the existing battery compartments. A large plus smaller capacity (boat) battery were considered and Varta contacted for their opinion, which was that it would work, but we would not get any additional capacity from that of two smaller batteries.
Two Varta AGM 85Ah LAD85 were fitted side by side in the starboard battery compartment and the engine battery moved to the port compartment.

In addition a 40W solar panel was fitted with controller wired directly to the boat batteries.
Noodle also has an Adverc alternator regulator - modifications to the alternator were easy compares to the boat wiring, which is not all shown on the Jeanneau wiring diagrams.
Overall aim was to maximise the amount of battery capacity within the existing space constraints. minimise the power requirements and introduce other methods of maintaining the battery power.
Most of the internal lighting was already LED. Those that were not (spots-halogen) have been replaced with LED equivalents. Masthead lights are now LED.
Jeanneau supplied boat with a Simrad SonicHub sound system, which is powered from a fused supply - it has no switched power input. With the SonicHub turned off, it still draws power. Fuse has been withdrawn and eventually will have a switch.
Performance - need more experience of the system since fitting to provide a reasonable analysis.
