The boat I'm acquiring has one battery at present (not sure whether its 80Ah or 110Ah. I'm not intending to fit an invertor or any additional heavyweight 12v devices but I would like to fit an onboard battery charger so that when I'm onboard at the marine I can keep the charge topped up.
Done some "googling" and the prices seen to vary dramatically. It does seem that a 3-stage would be suitable and Amperor do a 25Amp unit for around the £80 mark. I'd plan to use a 240V powerline plugged from the shore into a socket mounted on the cockpit/rear cabin bulkhead. From there, the 240v supply would feed either an MCB or RCD/MCB (whichever is more correct) with captive wiring to the charger . The latter would be mounted as close to the battery as possible allowing adequate ventilation but with the shortest 12v leads possible with the latter fused 50A/60A in the to the positive battery terminal. The 12v wiring in the correct gauge will be fused 50A/60A to the positive terminal.
The existing battery circuits for the lights, etc, will be kept "as is" through the existing battery isolation switch.
Any views would be most welcome. Regards to all. |

The Optimate info suggests that 50aph is the maximum size of battery so, as Dean says, the charge rate will be too low for the batteries we use. |

Thanks for your advice. I'll continue ruminating for a few days methinks!
All the best |

That's a nice piece of kit and will maintain a reasonably well charged battery brilliantly.
There is no max current shown on the site, but as it is designed for small motorbike batteries I guess it is quite low. This would not recharge a fully depleted leisure battery in any reasonable time.
