Paul makes some good points but I want to remind everyone that there is no
such thing as a drop in replacement lithium battery for boats.
Accommodations must be made on the charge side. Charge profiles need to be

On paper the VMAX batteries look very good -actually a lot better than very
good.
I would be pretty surprised if they can actually do what they claim, but I
don’t know that they don’t. This brings up the main issue with these batteries,
many of them get quite erratic reviews. You might get a goo

something (like this) is not your area of expertise.
I just found this on my Balmar regulator instructions, which gives me pause .

This is exactly why if I go lithium, the charging will work as follows:
Alternator > Start Battery > DC-DC Charger > Lithium Battery.
I also have the temp sensor on the alternator, which should help keep it from
being roasted. That still doesn’t help with the issue of the BMS opening.

I don't know Prowse, but would hardly call him a hack. He has reviewed
batteries and found that the advertised specs were not true and has exposed
shoddy construction.
He's not an engineer, but never claimed to be. He's just another free
resource out there in the wild.
My 2 cents

On Wed,
It sounds like you need to do a complete re-fit – batteries, charger,
alternator – and not simply swap batteries.

That is as it should be. Long story with the hurricane, but a battery box had
cracked, I hadn’t got a replacement for it yet, and trying to get upwind and
upcurrent in a hurricane was not only futile, it was enough of a beating to
crack the battery and crack the case more. The stinky acid soluti
I’d have to experience a roll-through to be concerned about battery movement on

Hi All,
Just to throw another idea out there.
I've just bought a Bluette AC2000p and plan on hooking up my 4 100w solar
panels directly to it. then using a Blue Sea Systems AC Rotary Switch "Off
+ Shore Power + Generator Positions" to wire it to my AC panel.

My boat use is for pleasure, not live aboard or extended cruising. Keeping up
with even the simplest systems, when there are many of them, is enough

FWIW, I periodically revisit this issue as technologies improve, and so far I
have reached the same conclusion as Charlie. For how I use my boat, my
old-fashioned lead acid battery system is good enough.

While on the topic of wiring alternators to batteries, Balmar has a “new”
alternator protection module. Worth $70?

It might be. I have the cheap version that is a $2 Zener diode across the
alternator. They do help, but any sustained overvoltage will burn them up –
literally.
Given how much a Balmar alternator costs, I might get one of these, especially
if I was trying to directly charge a lithium bank. They
