I'm fixing up my 42ft 'er to start cruising. But I feel like I need to start watching my budget
or I'll run out of money
before I even get out. I've been set on getting Li-ion but I'm starting to look at Lead Acid more closely.
I easily have room for 12 Trojan 6v Golf Cart style batteries
below, and to be honest, I could use a little extra weight on the bottom. (She's a high side ketch
with lots of rigging
and once she starts moving side to side, she starts swinging like a pendulum, I'm planning on lightening up her rigging
but that's another post) so I'm thinking the added weight is a plus.
Also, I know the FLA take a lot more maintenance
but the battery
boxes are all easily accessible from the top so adding water
will be easy.
Plus all the battery
boxes are in the engine
room and I hear that LiFePo4
don't like heat. So that makes me lean towards FLA.
And FLA are available everywhere in the world.
What are the cons I should be considering with FLA, beside life expectations? I know they don't like to be heavily drained but with 12 of them, I don't think the drain should be to excessive. But I haven't run any numbers yet. I would like to add a water
maker and a freshwater power flushing head
, I have a top loading refrigerator
and I'm going to look at an ac unit for the aft cabin
, and navigation
.... I know all that can add up. Hmmm. Do you think 12 6v Trojans with be enough? I will have 4 100w solar panels
(I'm playing with idea of separating the panels
into port and starboard sides, so when shadows fall one way it won't affect the charging
on the other side but that's also a difference post)
