Should I bother I insulating the aluminum bracket in case of accidental contact with the terminals?

Default I would

I would probably insulate it…a piece of silicone baffle material between the battery and holder would likely work…

Default Odyssey Battery Mount for Earthx

Odyssey makes their own hold down kit for their PC680. Does anyone know if the Earthx ETX680 will fit in the Odyssey mount? The Earthx is.1 inch wider but from the pictures, there may be enough room.
I bought an RV-3 with the Odyssey battery in an Odyssey mount. The battery is getting a little weak and I am thinking about a replacement. I like lithium but not enough to install a new mount.

Default Dynon HDX fault monitoring

The EarthX instructions say to set up the EMS input as “active low” and “alarm” type. I don’t have those options available when I attempt to configure pin 20. Can someone provide advice on how to configure the fault monitoring? I’ve attached a picture of the selections that I have available.

Set it up as contact on that page. Then on the Sensor Input Mapping page where you can set alarms, you set it to alarm below, say, 2 volts. That pin will normally have a slight voltage on it from the Skyview high-impedance pull-up resistance internally, and when the battery faults the wire will be grounded internally to the battery, pulling that voltage down to zero. As the voltage falls below the 2 volt (or whatever) threshold to zero, it should turn ON the widget alarm on your panel.

See the tail end of section 7 (EMS setup) in the installation manual.

Thank you! I’ll give that a look tomorrow.

Default EarthX battery mounts

Just posted this in another section. Perhaps someone may be able to use these mounts:

As with many of my projects, things that seem simple, are not so simple. I came across a few issues while switching from a PC680, to the EarthX 680. I have a few pictures, and some configuration instructions that may help someone who is doing a similar upgrade.

If your battery box is located aft and you have the aluminum battery hold down, you will likely need the terminal adapters that EarthX sells. This is because of the difference in terminal location on the two battery's.

Next, Its probably a good idea to insulate the hold down bar from the terminals in case of accidental contact. For insulation, I used baffle material encased in a big piece of heat shrink tubing. The heat shrink tubing does a good job of holding the baffle material in place on the hold down bar. I also made a small pad out of the baffle material. This sits on top of the battery to provide some room between the terminals and the hold down bar.

The EarthX fault monitoring instructions were a little lacking. I found SkyView configuration instructions on the Dynon Forum. They worked great! The last step is important. You have to actually display the widget. See below.

1) Connect the EarthX fault monitoring wire to any unused General Purpose input (type = A or C) on the SV-EMS-220. (Pins 4, 7, 8, 9, 10, 11, 12, 20, 21, 22, 23, or 31)

2) Configure the input in the EMS SETUP> SENSOR INPUT MAPPING. FUNCTION = CONTACT, SENSOR = CONTACT, NAME = EARTHX (select CUSTOM and enter a suitable name)

3) Configure the EARTHX CONTACT in EMS SETUP> SESNOR SETUP.
ALARM = SELF-CLEARING
MAXIMUM GRAPHICAL DISPLAY = 5.0 VOLTS
MINIMUM GRAPHICAL DISPLAY = 0.0 VOLTS

RANGE 1
ENABLE = YES
NAME = ALRM
COLOR = RED
TOP = 1.0 VOLTS
BOTTOM = 0.0 VOLTS

RANGE 2
ENABLE = YES
NAME = (NOT SET)
COLOR = BLACK
TOP = 5.0 VOLTS
BOTTOM = 1.0 VOLTS

Ranges 3, 4, and 5: ENABLE = NO

4) Place the EARTHX CONTACT widget on the 100%, 50%, and 20% EMS screens using the EMS-SETUP> SCREEN LAYOUT EDITOR


Hopefully this helps someone else!

The only thing I have left to do, is to properly configure the battery voltage widget. According to the EarthX instructions, the normal voltage ranges are quite a bit different than a standard battery. Again, their instructions were a little lacking. Below, I have listed what I set up thus far. I need to decide on what the normal voltage range (green) should be.
If anyone would care to share how they have theirs set up, it would be appreciated.

Max 18v
Min 11v

Range 1
Red 18-15v

Range 2
Yellow 15-14v

Range 3
Green 14-13v

Range 4
Yellow 13-12.6v

Range 5
Red 12.6-11.0v

Normally my “green” is 13.6 to 14.3 volts. Anything above and below probably user preference. Since I have a set-able voltage regulator (B&C) I have it at 14.2 both batteries so 14.3 appropriate. You can charge these batteries up to 14.6 and if so probably 14.7 more in line with “green settings”.
