Not to disparage anyone but have a look at the battery manufacturer's
specs and see whether they recommend that high a charging rate. I
suspect you'll see something like 10 - 15% of rated capacity.

Nope. My battery manufactuer recommends charging with a voltage
regulated charger at 14.2-14.4 volts.* That's what I do. And as I
say, many other boats are doing this, too. It has worked well for me
for years and AFIK it works well for other folks also.

My battery manufacturer recommends charging to 14.8 and then dropping
back to 13.2, see:

If you stop when the batteries first reach 14.8 you never fully charge
your batteries.


Not to disparage anyone, but where are you getting your information?
You sound very sure of yourself. However, what you are saying doesn't
fit with my experience or with the advice I have taken from a pro. Do
you have any sources or experience you can point to?

Try

Note that my figures were too low for some batteries. Trojan
recommends 20% but other recommendations are in the 10 - 15% range
