Hardwire your LevelMate Pro for under a buck!

[Snackchaser]

The LevelMate PRO is excellent for quickly leveling the trailer, and the battery is supposed to last six months.  But I often forget to turn mine off and it always seems to be dead when I need it.  In fact, it’s died so many times that I even kept extra batteries taped on the cover, quick release thumb knobs, and a screwdriver in my hook-up kit for changing the battery.  Then on top of that, it has to be recalibrated for the slightest alignment changes when removed for battery replacement.

I was fed up, and not willing to shell out another $150 for the USB powered LevelMate PRO+.  So I spent $9 for a pack of ten voltage converters, and I hardwired the LevelMate to the trailer battery!  The converters have an input voltage of up to 16VDC, and an output of 3.3vdc.  They're small enough to mount inside the LevelMate case, the parasite drain is next to nothing, and the power switch will still remain operable.

This is a simple modification requiring only basic electrical knowledge, some wire, a fuse, and a soldering iron!  For the wire, I used an old charger cord.  Hardware or auto parts stores will carry In-line fuses.

Procedure:

1. Open the LevelMate case and discard the battery
2. Use a glob of silicon sealant to glue the converter on the LevelMate circuit board
3. Drill appropriate sized hole for the power wire
4. Verify the factory soldered a bridge across the Converters 3V3 pads to set output to 3.3vdc
5. Solder jumper wire from converter GND to LevelMate battery pad marked “-”
6. Solder jumper wire from converter VOUT to LevelMate battery pad marked “+”
7. Solder Negative power wire to converter GND
8. Solder Positive power wire to converter VIN
9. Connect power wires to any negative and positive power source via a 2 amp fuse.

My LevelMate is mounted in the garage space for optimum BlueTooth range close to the leveling switches.  Power is available from the garage light, or you can pick it up from the “load side” of one of the breakers under the street side bed, or the dc power panel.

Note:  This converter has a input of 4.5 to 16 vdc.  Don’t be tempted by myriad of attractive looking 12vdc converters because they will not withstand the Oliver’s 14.5 vdc charging voltage.

Now if I could only come up with ideas for the extra nine converters. . .

Hope someone finds this useful!  Cheers!  Geoff

The LevelMate PRO does have a Sleep Mode to conserve battery life if left in the on position, and oftentimes I think the battery is dead next use. However, hearing two beeps when toggling the switch off then on again indicates the battery is still good; no beeps, time to change the battery.

It sure is! And as usual Geoff...
You can wire anything that comes to mind (we are not worthy) 🤣!

This is a GREAT upgrade for anybody who already has the PRO vs. the preferred PRO+.

When we were shopping for ours two years ago, I came close, but soon realized the PRO+ included a wiring harness. Anybody reading not have one, OMG get one and pay $120 for the PRO+ vs. $100 for the PRO. I paid $102 Nov 2023 for the PRO+!

I stay in the driver's seat of the truck to level. I open the app and move back and forth to get as close as possible. Then Chris gets out after I tell here where to place the Andersen levelers. When she gets them in place, I pull up or back depending and we can be at near perfect level, set the parking brake and we're done! Running this device on battery - OMG NEVER! I would be truly upset if the app could not find the device (for a dead battery).

I wired ours under the rear dinette seat, where our B+ and B- buses are located in reach of the PRO+ included wiring harness (no splices or butt connectors required). The side of the PD ATS provided a good horizontal surface, installed in a just few minutes (see pic). 

We would not leave home without these accessories:

If you have the PRO, certainly work Geoff's mod ASAP!
If not, buy the PRO+ and if you do not have either...
Get out of the dark ages! 🤣 (life is short)
