I have an acs0714 microchip that reads up to 20 amps and connects to a micro-controller.
I am at a total loss on where to hook this thing up.
I want it to operate like the old style amp meters. Left discharge, right charge.
I can not think of a place that would show both?
If I hook it bat to voltage regulator that shows charging.
If I hook it bat to 12v bus that shows discharge.
The chip is bidirectional so it will read in both directions.
Thanx for your help.

Don;
The only device which both charges and discharges is the battery. Therefore
the only lead where you can measure this charge/discharge cycle is the main
battery cable to/from the battery. (Or technically also the ground cable to
the battery as an alternate) If you don't want to "see" starter currents,
then you'd monitor the main cable feeding the rest of the system beyond the
input to the starter contactor. You might want to research the usefulness of
this information before going to this trouble however. The simple low
voltage warning combined with over-voltage protection gives you much more
valuable information, potentially much sooner, than any ammeter indication
will. The low voltage light will grab your attention right away whereas it
may take a while to discern a battery discharge on an ammeter especially if
the discharge is small. A conventional ammeter measuring battery current
will typically read zero most of the time. With light loads and only an
ammeter you could potentially drain the battery to the point of being
totally useless and never know until everything goes dark. Not the "best we
know how to do" paraphrasing Bob K.

I'm looking at ammeters in the spruce catalog. They don't give much
information.
Are there any 2 1/4" aircraft ammeters that use a hall effect sensor? I'm
guessing they'd mention it if they did.

| Subject: | Battery Maintainer and Dual System |
I picked up the Schumacher 1562A Charger-Maintainer...It looks like a neat unit...
Two questions...I would expect it should be a good choice for the odyssey batteries...right?
When I get around to attempting to put a maintainer on a dual system with two batteries,
any good ideas on hooking up a maintainer?
Do you think a person should use two maintainers, or attempt to charge both batteries
with one? I can see some potential for screw ups using one...
Thanks,

I have 3 batts in my shop hooked up in parallel to one 1562A and sure
enough all three are fully charged when ever I check them. For my
rolling fleet I use a separate 1562 for each one. Its hard to drive
them all so the maintainer keeps them all topped up.

Paul, I was under the impression that due to differing states each battery
will have to be charged separately to keep it "full" ?
