Hi All
I want to add a third bank of batteries as a house bank in my 265x. I have read a lot and it is all good stuff that will help me immensely. I currently have 2 27m batteries all in the original set up. What I cannot seem to find is information in where the third bank batteries are actually situated. All help is greatly appreciated.
 
On my 265 the house battery was on the starboard side next to the battery for the starboard engine. The switches were next to each other in the same compartment.

Thats where my current batteries are. I would like to add one (maybe two joined) to create a new house bank (third bank) and am wondering where they could be placed. Tks for the response.

If you haven't read this thread, please do.


My 2000 265 had two banks using three 24dual purpose batteries. two on stbd side were house/stbd start and one on port side was port start.

I switched to three banks with 4 batteries using two 24Ms for start and two 24 deep cycle in parallel for house. (at one point they were all 24 dual purpose and that worked fine)

I don't imagine you could get two 27ms in one side. I don't know how anyone gets even one 27 in there!
