Power needs for new liveaboard
I’m buying a boat and have got through the survey part. My question is one for opinions from experienced boaters on power.
The listing stated 3 leisure batteries. I personally saw 2x260ah (two sixty)but really it didn’t occur to me to shine a light further under the deck to see what else was there.
The survey indicated 3 leisure at 250ah ea. (two fifty) but noted access was difficult. “Only two were able to be seen, the others behind fixed panels”
As part of the negotiations and since the batteries need replacing the quote from the marina stated there were only 2 x 260ah leisure batteries.
The boat has no solar. I would prefer to not have solar added (expense/looks). All the while I was Mentally getting comfortable with a bank of 780ah (of course that’s not actual available) but now I’ve essentially been cut by a third down to 520ah to start with.
I have no experience in actual usage and am trying to determine if I should be overly concerned with the now reduced battery capacity.
I do not plan on having a tv - if I do it’ll be 12v. The fridge and separate freezer box are 12v. Heating is via Eberspacher Diesel.
Side note. Should I decide or need to add a third battery of same size and brand - I would do it within a few months of purchase - is this a simple case of connecting with cables to the current two? IE a diy. Assuming space of course.
There is a 3Kw inverter multi plus on board. I plan on being a continuous cruiser so take into account week long stays.
Thanks in advance.
