Deep Cycle 12V Batteries

[Steve Skelton 1Participant @steveskelton1]

Ian, The battery usage and voltmeter (which is directly connected to the battery terminals) has been checked with a calibrated voltmeter. Unless I had a big Li rechargeable battery the DC-DC would not benefit a great deal and if I had a big Li battery I would be using it as the service battery.

The old batteries were sealed units so I may have cooked them. I will be replacing them with refillable flooded lead acid.

Peter,the fridge is quite efficient but has a front opening door which is a damned nuisance as all the cold air escapes when taking anything out of the fridge. The fridge cannot run on gas and if I could I would like to replace the gas cooker with a diesel powered one as LPG on a boat is dodgy in my opinion (I used to be registered with Corgi/Gas Safe).

I do have a solar panel but it is a pain to set up and only delivers about 1A in bright sunshine.

I am looking to using two smaller solar panels and would appreciate any advice on them – am looking at about 0.6 x 0.6m units with a max rating of 50W each. I have a PWM solar controller.
