Installation and Wiring-Overview
The RS-BM500 shunt should be mounted as close to the battery as possible, and the remote display is intended to be mounted on a wall.
Recommended Tools
- Wrench
- Drill
- Jig saw
- 2 ring terminals of appropriate size for battery cable
- Crimp tool for ring terminals
Wiring Diagram
The following wiring diagram will be referenced in the next section.
Installation
- Before doing anything, disconnect all wires from the negative side of the battery.
- Cut the negative cable for the battery and crimp on new ring terminals. Alternatively, use a new wire of appropriate gauge to carry the full current demand of your system.
- Install the shunt as shown in the wiring diagram above.
Note: The negative terminal of the battery must connect directly to the“B-" side of the shunt, and there should be no other connections to the negative terminal of the battery for accurate measurements. - Use the B+ wire included in the package to connect the B+ terminal of the shunt to the positive side of the battery.
Note: Do not stack smaller terminals under large ones. - Connect the shunt to the remote display using the included shielded cable.
Mounting the Remote Display
- Plan the location of your remote display and keep in mind there is a cable that needs to route all the way to the shunt.
- Drill a hole in the center of the planned location and use the jig saw to cut a hole according to the following picture.
- Connect the shielded cable to the shunt and route it such that you can bring it through the hole.
- Connect the shielded cable to the remote and snap the remote into place.
Basic Setup
- Hold the "Ok" button for 3 seconds to enter the settings screen. The up and down arrows are used to navigate as well as change parameters. The "Ok" and "<<" button are used to enter and exit a setting.
- Set the "CAP" setting to match the capacity of your battery or battery bank.
- Optionally set the "HIGH V" and "LOW V" values to the voltages at which you want remaining capacity/percentage to reset to 100% and 0% respectively.
- Alarm is the minimum Ah value that will trigger an audible alarm.
- Once all of these settings are complete, hit "<<" and your BMK is set up.

Amazing - Stop Scrolling and Buy This Pillow
Size: Queen (Pack of 1), Color: White
I have been an Amazon customer ever since the very beginning, and this is my first review. Not because I haven’t purchased tons of amazing things (and a few bad ones), just never felt the need.
However, I researched pillows for longer than I care to admit, and decided on this one.
I’ve had it for about six months and absolutely love it. No lie, I genuinely look forward lying my big head on it after a long day.
I am a side sleeper, but flip flop all around through the night and it’s great in every position.
Pros:
Stays nice and cool, which is soothing regardless of the time of year.
Has a sort of quilted textured pattern on the zip up cover, gives it a luxury feel, that breaths nicely even when a pillow case is added.
The fill is fully adjustable to your preference.
I knew it came with extra filling but was worried it would not be enough. Wrong. It was very full and I ended up taking some out until it was perfect.
It comes vacuum sealed and suggests it may take some time to fully take shape. However, I found it to be about 90% almost instantly and was sleeping on it a couple hours later.
There was no unpleasant scent sometimes associated with memory foam items.
The foam itself is very nice, a mix of what appears to be shredded and cotton candy cloud like. Very brilliant idea, as it is somehow supportive, soft and firm all at once.
The affordability of this pillow compared to some of the others in this category can’t be overstated.
Oh, and the packaging was very thoughtfully and securely done.
If you are like me, an over thinker, I would suggest just taking this for a spin. It’s amazing.
I’m not a bot, or working for the company. I’m just truly satisfied, love this pillow, and have been sleeping great.

It's the perfect pillow!
Size: Queen (Pack of 1), Color: White
I purchased this pillow specifically for its customizable fill feature, which allows you to add or remove stuffing to suit your personal comfort needs. Due to the unique curvature of my cervical spine—forward at the neck rather than backward—I require a soft, semi-flat pillow rather than one that is thick or firm. Additionally, I often experience ear discomfort by morning, so a gentler surface is essential.
Upon adjusting the fill, I was pleasantly surprised by the generous amount of stuffing included. There was enough to fill an additional pillowcase, and I estimate it could easily create four to five more pillows. The ability to modify the pillow’s firmness at any time is an outstanding feature that makes it adaptable for a wide range of preferences and sleep styles.
This pillow has exceeded my expectations in both comfort and versatility. I highly recommend it to anyone seeking a personalized sleep experience.

Good quality pillows overall
Size: King (Pack of 2), Color: White
Got a set of these for my wife and myself as we were struggling with our old pillows. These have some really good qualities and some things we'd like to see changed.
First, the good: These are look and feel like they are high quality and made with good materials. The foam itself has a very nice feel to it. We love the fact they are adjustable to add or remove foam. They come with a pretty substantial amount already in the pillow. We appreciate the CertiPur certification.
Now the improvements or changes we'd like to see: The foam, while feeling great, doesn't bounce back well if you scrunch your pillows, and so every day you have to fluff and reshape the pillow, moreso than some other memory foam pillows we've owned. One side of the pillow is cooled and you can feel that even through the pillow case, and that's a great thing. However, one side is not cooled and we'd have preferred if both sides were made of the cooling material.
Overall, these are good pillows and we are not disappointed with the purchase. They are not, however, our perfect pillows (which do seem hard to find), and at some point in the future will probably make their way to the guest bedroom. We would rate them as some of the better pillows we've tried and feel most people would probably like them.

Perfect Pillow
Size: Queen (Pack of 1), Color: White
These are the best pillows ever. You can adjust the firmness or softness to whatever you want. For years i used a soft latex pillow , which you cant get anymore. I will never use another pillow. I have purchased 6 of these after the first one. You pick your own comfort level. Best ever. No more neck aches.
