Looking for an update on batteries.
So, looks like the current choices for most of us trawler folks are, in order of purchase price:
Plain lead acid
Cheapest to by, high maintenance, short life
AGM
Minimal maintenance, needs smart charging, and it cared for last long.
AGM foam, Oasis Firefly
Also minimal maintenance, high claims for longer life, more discharge flexibility and a better value.
Lithium
Expensive to purchase and charging is critical. Need to monitor carefully. However, very long life, large flexibility in discharge capability, very fast charging (but need expensive high output alternators and regulators). Light weight and space savings. Arguably the best if you're keep your boat for a long time.
Thoughts and questions?
I'm thinking of the Oasis if the claims can be verified. Question: They say larger discharge capability, but can the voltage be held longer so one really gets more use from the battery? And, is there truth that they really need to be topped off for charging at least once a week?
Lithium sounds great, but at a cost just for the alternators, serpentine belts kit, and regulators, it's close to $4500, plus the high cost of the batteries, gets VERY pricey.
