The best way to ensure you can always start the engine is to have a dedicated
starting battery that is directly connected to the starter motor solenoid and
serves no other purpose. Connecting to the house bank through a switch will
provide a means of emergency starting if the engine battery sudd
Mark,
Just keep in mind that the voltage method is not very accurate...though
neither are the A-hr meters if they are not periodically recalibrated.
That being said, I believe that my method errors on the conservative side.
Just in case I do forget (or lose my shore power) I installed a Priority
On Imzadi I have a Blue Seas digital voltage meter that I installed several
years ago. It will monitor three battery banks, is very accurate, and I am
happy with it. Knowing the voltage gave me a rough idea of the state of
charge of each bank.
But a couple of years ago I helped move a "real" cr
Yep a volt meter like that could work. I have a tank sensor from
tankedge.com that has battery voltage monitor and adjustable low voltage
alarm. That's at the nav station. On deck, my GPS/chartploter monitors
voltage and also has an adjustable alarm.
You might try one of these before doing some
Hi Mark
Two concerns with that meter - it isn't likely sealed, and it does not
mention how much current it draws while on. The first you could address
by buying a couple of them for spares, and I'd wire it up in line with a
"momentary on" switch so you only have it powered when you press the

monitoring from 2011
his newer article (which is linked in that original one) suggests
that a Balmar Smart Gauge us a better option.

Josh,
Thanks for the info on using voltage to gauge battery level.
With my tiny bank and very limited loads it does not make sense to
be wiring in a monitor or Balmar Smart Gauge (to the tune of $360
cdn). But I was thinking about adding a voltmeter so I could
Dave,
I just installed a battery monitor made by victron. Haven’t really played with
it yet but it does all of the things you are asking about and is easier to
install than the Link monitor. Good article here

What you are looking for is an amp-hour meter. Discharging a flooded deep
cycle battery rated at 100 Ahrs below 50% should be avoided. This roughly
equates to 50 Ahrs of use. 5amp for 10hours or 50 amps for 1 houryou
get the jist. Discharging a flooded deep cycle below 50% will decrease its
David,
I have a Link 2000 battery monitor on the Enterprise. Highly recommend it.
