Thank you for the video. I’m in the middle of installing the Victron BMV-712 and temp sensor, and the temp reading was all over the place. It was reading anywhere from -1 degree C to 122 degree C within a few minutes (how’s that for global warming, lol). All other videos instructed me to leave the black wire from the sensor off, but you’re the first and only one that said to plug it into B2 of the shunt. So I went outside and plugged the black wire in and boom; it works! I thought it was a defective sensor so the seller was going sending me a replacement. I notified the seller but I hope I caught him in time.

Great vid. The relay comments at 21:40 seems like they may be misleading a bit. The monitor/shunt are unable to toggle current into/out of the battery/batteries. There’s relay contacts on the back of the monitor (NC[normally closed], COM [ground], NO [normally opened]) that can used to trigger an external device to turn on/off like a charger. Just learning all this myself for a DIY install.

@Timo I see what you mean. I never looked into the relays any further than what I could discern from the manual as our Battleborn batteries have a built in BMS that does everything that the Victron relays are supposed to do to protect them. I did not realize that an external device would be needed to use the relays. Good info. I just did a search on "relay" in the manual and I must say that Victron did not make it clear as to how the relays needed to be set up for use (unless I'm missing something). Even the Quick Start Guide only shows 1 picture that points to the Relay connections on the back of the monitor and shows nothing else such as wires leading to an external device, etc.... I couldn't find anywhere in the manual stating that the relays needed to be connected to an external device. If you wouldn't mind, can you provide any links to KZbin video resources that you may have come across detailing this? Or maybe a link to another source? I did a quick search and couldn't really find much. Thanks!

By way of cables, if you are going to add solar, an inverter and do this kind of stuff, having a selection of welding cable, good thick closed lugs, adhesive double wall heat shrink, and a crimper might be worth the investment. You can make the exact length you need, with the lugs “clocked” as you need, so as not to twist the cable.

I do agree that I could have left the fuse in when connecting the leads to the battery, however, the manual has the following statement: "After inserting the fuse in the positive supply cable to the main battery, the BMV will automatically start the setup wizard". That is the reason why I installed the fuse after the battery was all hooked up. I believe their main concern is that the batteries should always be connected with the positive lead first and the negative lead last. I have always left the fuse in when disconnecting and reconnecting since the original install and have had no issues. Hope that helps clear things up! Thanks for watching and commenting!

@Brad White Glad it was helpful. The shunt would need to be wired to one end of the battery bank on the negative terminal with no other negative wires attached to that negative battery terminal.

@Brad White Sorry, just saw this now. If you have 12V Batteries, you would usually wire them in parallel (positive to positive on all batteries and negative to negative on all batteries) to keep them at 12 Volts if your camper has a 12V panel which is typical. Not sure how you wired your bank though. Here is a link that shows both "Balanced" and "Perfectly Balanced" 4 battery banks wired in parallel (scroll down till you see them). www.windynation.com/jzv/inf/how-configure-battery-bank Substitute the positive connection (where they show the controller connecting to the battery bank) with your house wires, inverter, etc... and then the negative from the battery would be a single wire connected directly to your BMV shunt. On the opposite side of the shunt you would connect the negative wires from the house, inverter, etc... If you have a lot of wires to deal with, you can use positive and negative bus bars to clean them up. One note would be if you are wiring in the "Perfectly Balanced" configuration, I would recommend moving the 2 lower batteries up beside the other 2 to form a rectangle as you want to try to have close to the same length wire running from battery to battery. Sorry if this isn't the answer you are looking for. It's hard not being able to see your current setup. Let me know if this makes sense.

@EddieAtLarge2 жыл бұрын
@Mallory McGuire Do you have power to your camper and are just not seeing the lights on the Lynx distributor? If so, it may be because you don’t have a Victron BMS or Victron Shunt (These are different than the Victron BMV-712). I do not own a Lynx distributor, however, a creator that I follow has an entire series set up for these products. Here are a few links to videos that may help you make sense of the issue. The first talks about general information on the products and the 2nd is a hack to get the lights to work on the distributor when you don’t have the Victron Shunt or BMS. It seems ridiculous to me that this would need to be done to get the lights to work. And adding the Victron Shunt that doesn’t have Bluetooth like the BMV-712 Monitor does not seem like a good option either. I would recommend showing these videos to your installer and see if he can do the hack or remove and replace the Lynx with normal bus bars and fuses. I guess the last option would be to live without the lights, however, that seems to defeat a big part of the purpose of having the Lynx.

@Rich Bring Here's a good article that will give you an idea of why this may have happened. The residential refrigerators use a ton of power and will drain your RV batteries in no time at all.. www.gonewiththewynns.com/rv-residential-refrigerator-power The first thing I would recommend for you to do is to get rid of your stock batteries and buy lithium. Here's our video on changing over to lithium. kzbin.info/www/bejne/hoXMhaeVoNalmtE We only had one lithium battery when we made this video, however, we now have 3 and are REALLY happy with them. Prior to this, we couldn't even make it through one night of running our furnace with the stock AGM battery that came with the rig. Yes, the lithium batteries are expensive, but, they are worth it and will pay for themselves over time. And keep in mind, you can drain lithium completely without damage whereas lead acid or AGM will be damaged when drained below 50%. Therefore, you will have double the capacity with lithium. Hope this info helps. Feel free to let me know if you have any other questions.

@EddieAtLarge2 жыл бұрын
Hey Tim. You’ll need to know the max number of amps of 12v DC current you’ll be using at any time to calculate the wire size. Here is a link to a wire size calculator that I use. www.explorist.life/wire-sizing-calculator/ This guy also has a ton of great videos on KZbin. If you’re not using an inverter and you haven’t made any modifications to the camper, you can figure that the max wire size needed will be the same wire size that currently feeds your campers DC system. So you can look at the wires coming off your battery bank positive lead and the biggest wire is the size you would need to use for the negative wire running to the monitor. This is typically 4 AWG or 6 AWG unless there is a factory installed inverter. If you have an inverter or plan to install one, the wire size will need to be much larger. Example: A 2000 watt inverter will require up to 167 Amps at max power (2000W/12V=167A) You’ll then need to add any other potential 12V amperage that your camper could be using at the same time. Typically, this will be the max amperage that your converter/charger will generate. Our charger can send a max of 50 Amps to the batteries. Others can be higher. Take your total amps (ours would be 167+50=217) and plug that into the calculator. You’ll then need to measure the total length of the wire running from the negative battery terminal to the battery monitor and double it. So if it’s 3’ total, you’ll need to use 6’ in the calculator. The calculator tells us we need 2 AWG wire for our example. Again, I highly recommend checking out Explorist Life on KZbin. He does a great job explaining electrical. Hope this helps!

@EddieAtLarge2 жыл бұрын
In the video, I stated that I had it at 0% initially and when I added the setting parameters from Battleborn, it changed it to 5%, therefore, I left it at 5%. After doing a search, I've found that the discharge floor setting only influences the battery level "Indicator" that can be seen in the bottom right corner of the display (not the app) and does nothing else. Here is a link to the question and answer on Victron's community website. community.victronenergy.com/questions/78448/bmv-and-discharge-floor-impact-on-soc-reading.html So really, it should probably be set to 0% per this information. Regarding your comment where you thought it should be set to 20%, I believe you are referring to the possibility of the battery being damaged if it would get below 20%? Battleborn has a protection setup with their BMS that is called "Low Voltage Disconnect" that will automatically shut down the battery when it falls below 10V which per the lithium Voltage chart is 0%. Then the battery has to be jumped to "wake it up". They claim this will not damage the battery as long as it is restarted within 5 days of going into LVD. Here is a link to that article: battlebornbatteries.com/low-voltage-disconnect/ If you don't have Battleborn batteries, you will want to check with your battery manufacturer to make sure it has low voltage disconnect protection.

@Laughing Ram Hey Ram! Glad you liked the video. Hope you've been doing well! So, the BMV-712 can monitor your 2nd battery that is in the separate compartment, however, it will only give you the very basic voltage reading and nothing more. If you want to check out the diagram for the this option, click on this link and check out diagram 11. www.victronenergy.com/upload/documents/BMV-712-quick-installation-guide.pdf The only way you would be able to have it read and display everything for both batteries is if you would create a battery bank by wiring the batteries in parallel. If you wire in parallel you will double your amp hours and keep the voltage the same (12v). What is the distance between the batteries? Option A is also possible, but, you will only have info from the monitor for the one battery. Option B if I'm understanding correctly would not work. Option C is what I described in the first paragraph. Option D is the easy option, but, not cost effective Hope that helps!

Thanks Ed! My batteries are approximately eight feet apart. They are both basically in a sealed box with a positive and negative load connection in each. I’m not crazy about drilling a hole in the side of the box. The batteries are already in parallel. (Two 12 volt batteries supplying 12 volts) Therefore I would think if I just hook the monitor up to one battery it would be okay, as long as the batteries are in parallel and equal type. So if it shows that the one battery is at 70%, I would assume the other battery would be at 70% as well. Am I missing something? Not sure about picture #11. Where is the other cable on the second battery? I really appreciate you taking the time to post the info. We have a Lance 1985. Currently I just go out in the morning and the evening, when we have minimal load and put my volt meter on one of the two batteries. We usually are showing around 60%. We have been camping in the cold and have our furnace running some of the time in the night. “My Buddy” carries most of the middle of the night. I end up running the generator for about an hour in the morning and an hour in the evening. Kind of a rough way to do it, but it’s been working for us. However, it would be nice to have the battery status on my iPhone like our gas bottles are with Mopeka. Ram

@Laughing Ram No problem Ram! Glad to help if I can. If you need to drill a hole in the sealed battery box, you can always seal it up with something like silicone caulking or some type of foam material after the wire is ran. The 2nd wire on the other battery is not shown in the diagram for some reason, but, would have the main positive load connected there (as normal) as well as one of the red positive wires that come supplied with the BMV that is ran to the B2 terminal on the shunt. Are you sure the batteries are wired in parallel? For this to happen, a wire would need to be ran from the negative terminal of one battery, directly to the negative of the other battery and then the same for the positive. Then, the positive from one battery would be connected to the main load of the RV and the negative of the other battery would be connected to the ground lug or if you have the BMV hooked up, the "Battery Only" lug of the battery monitor shunt. Here is a link to a diagram for 2 batteries wired in parallel. Ignore the first diagram and go to the 2nd one down on the page for the proper hookup. caravanchronicles.com/guides/how-to-connect-two-batteries-in-parallel/ It doesn't seem likely that they would have ran wires like that over 8' from one battery to the other in order to wire them in parallel. One way to test is to see if the voltages match. Check one battery and then the other directly after and if the voltage matches perfectly, they may be wired in parallel. There can be a slight variance of 1/10th of a volt and that is OK: Example: 12.06 and 12.07 If there is a greater variance such as 12.06 and 12.12, then they would not be wired in parallel. In your situation with your batteries that far apart, I think your best option would be to go with 2 separate battery monitors, one for each battery. You can then monitor each via Bluetooth via the app and won't even need to mount the display. You'll still want to check them at a time when you have a minimal draw going like you've been doing to get the closest true reading. I can actually isolate my batteries by turning off the battery disconnect switch so there is no draw at all and that is the best way to check the voltage if you can do it that way. PS I also have the Mopeka tank sensors and love them.. Please update me when you decide what to do. Take care, Ed

@@EddieAtLarge My trailer runs 12 volt DC. With two 12 volt batteries, they would have to be wired in parallel. If they were wired in series, I would end up with 24 volts trying to go into a 12 volt circuit. Each battery is tapped into positive circuit and tapped into the negative circuit at their respective location. They would be still in parallel. Picture a double loop; one negative and one positive. Looking at drawing #11 again, if I mount the shunt in the left battery box, for example, it looks like the only wire I would actually have to run across from the right battery would be the small wire from the right’s positive terminal to “B2” on the shunt. The Negative cable on the right battery does not go through the shunt. So both the negative and positive cables on the right battery can stay tied to the circuits via the existing connections. It looks like only the negative wire on left wire has to be changed and routed through the shunt. Thanks again Ed, Ram

@Laughing Ram I can understand you logic and realize that they are not wired in series. I guess I was trying to say that they are not wired in parallel in the sense of creating a "battery bank". In order to get a true reading from the monitor, they would need to be wired directly together in parallel and not running through the entire system when connected. In your situation, I believe both negative cables from the batteries would need to be wired directly to the "battery only" lug on the shunt and all other negative wires would need to be connected to the "load" side of the shunt (from both batteries). Meaning that you could not connect any of the negative loads from the rig directly to the either battery or you would not have a true reading. You would then need to run B1 to one battery and B2 to the other (with limited data of voltage only readings on B2). Both would be a difficult task and the red positive wires that come from Victron would not be long enough for the 8' run. All that being said, I'm not an electrician or an expert in the field. My next suggestion would be to contact Victron to see if they can give you additional guidance. Please let me know if you do and get this worked out. Good luck, hope you can work it out! Ed.

At what point do you connect from your solar controller? I have mine connected to the battery terminals. My ground goes through a shutoff switch. That way while not in use my batteries stay charged and the system is de-energized.
@EddieAtLarge3 жыл бұрын
@Brad Spitzer I connect the positive from the solar controller to a positive side fuse block and the negative to a negative bus bar. The negative bus bar is then connected to the "Load" side of the battery monitor shunt. I have a shutoff switch (factory installed) on the positive side that I can turn off so there is no load being drawn. You do not want to have anything connected to the negative battery terminal other than a wire leading to the "Battery Only" side of the shunt or you will not get a proper reading on the monitor. Did that answer your question?

@Brad Spitzer Totally understand. I love being able to monitor the batteries with this. I just recently installed 2 more Battleborns, the solar and a 2000w inverter. Will be putting out some videos on all that soon. The monitor is a fairly easy install. Just need to get the settings right on the app for your particular batteries. Good luck with everything!

Hey Bob! Looked them up and they do look pretty cool. Looks like a similar BMS as what Battleborn has with protections for over/undervoltage, etc... Their website says that if you have multiple batteries in parallel, you would need to multiply by number of batteries in the bank to obtain the total amperage for the bank whereas the Victron monitor has that done already (not really a deal breaker). A few other differences are: Victron monitor also displays Power (Watts), Consumed Amp Hours and has a Time Remaining function that estimates time left for the current usage state (I don't necessarily care for the Time Remaining function and don't plan to use it). The relays are also a nice safeguard. I have parameters set for those as well as a backup to the Battleborn BMS protections. Thanks for watching and commenting!
