Thanks for explaining explicitly what goes into the P- of the shunt. Been trying to figure that out now for hours. Wasn't explained in any other video. The negative of the system. Understood now. Will try it out tomorrow.
Hi Alex, Great video thank you. But ........ At 13.3v your battery is charged to 90% and NOT 100% :-) So here's my question... When you charge any LifePo4 battery it charges quickly and then like our phone batteries, the charge slows down for the last few % until the resistance in the battery reaches about 14.2v at which point the charger turns off. So, at which point do we tell the battery monitor the battery is at 100% is it IMMEDIATELY after you stop charging (and thus the battery voltage is at 14.2v for a little while) or do we wait a certain period of time till it settles at resting voltage of 13.6 (which I believe is 100%). I appreciate any thoughts you have on this as it's not really made clear anywhere that I have found.
Forgive my ignorance, but if I simply purchased a single smart battery, and hooked it up in part of a system with other 12v 100ah would it adjust to read all of them if it were the only one with that built in feature? I am knew to all of this, thank you so much for your channel and kindness 🙏🙏
I have 2- 12 volts 280Ah lifepo 4 batteries. I'm building a system for my RV with solar panels. I will keep it in a 12 volt configuration. The total of the😢 Amp hrs. will be 560. Will any of the shunted monitors you mention work in this battery system? Also do you still recommend the renogy smart shunt on this system? Thank You!
I'm trying to decide on the 'monitor' to use for my Bioenno 30ah Lithium Iron Phosphate battery for my ham radio. I found your video while using Powerwerx BSM-500 as a search phrase.
What if you have 2 100ah batteries in parallel. You install the shunt on the front negative term. Then you install an inverter on the back negative and positive terminals. Will it still read the battery properly?
"one shunt per battery"? this answer doesn't sound correct. if the batteries are already connected in parallel, why wouldn't you just use a single shunt on the common negative which connects to the load. then in the shunt settings, change the capacity to reflect the total of the batteries. ? as long as all the current is passing through the shunt, the shunt doesn't know/care if it's one battery or more than one
Hi, I have two batteries, Basen Green 11.7kWh 51.2V (BG) and Ecoflow Delta pro 48V 3.6kWh with inverter (DP). With BG full DP. With the DP application, it is not possible to set the BG not to completely empty! What could I put between the batteries so that I can set a voltage limit at which the charging will stop and thus prevent the BG from being completely discharged? Is some Battery Monitor OK??
wow happy i just found this video. i was about to connect the exact same victron shunt to two power queen batteries in parallel without knowing they needed to be fully charged. i think i missed a step. the systems positive cable goes to inverter? not sure where that cable came from.
2:05 I think its not possible to get shocked with a 12V battery right? Because V=IR and skin is 10000ohms then max current is around 1mA which is not even perceptible.
Usually you'll have a negative and positive end coming out to supply whatever load you have. Put the shunt there. Add up the AH for all the batteries and plug it in.
unless your hands are wet, and you're doing something stupid, you will not be shocked by a low voltage DC battery.... also, how sad is it to see, a single incandescent globe along with the inefficiency of a big inverter rendering your big expensive 100Ah lithium battery/inverter system useless in about 24 hours!!!
Yes, incandescent bulbs are horribly inefficient. I just used one in this video to drain the battery quicker since it would've taken a while with an LED bulb.
Here's my review video of the best battery monitors - th-cam.com/video/IO1ztGEo8_Q/w-d-xo.html
Yes! Finally a video that show exactly how to hook up the shunt. Thank you very much.
You're welcome!

Can you access the battery status over the internet from a remotely location,? Bluetooth is limited to 50 feet.
Hi Alex,

This shunt is good but can only be monitored by your phone? No low voltage alarm beep, remote physical screen option to use in RV?
Thanks. This was the exact video I was looking for.

Please can this work with a 48v LiFePO4 battery?
Batteries with build-in BT have the same function and possibilities as the setup that u have?
What if you have 2 100ah batteries in parallel. You install the shunt on the front negative term. Then you install an inverter on the back negative and positive terminals. Will it still read the battery properly?
No. One shunt per battery

Which shunt should I use if I want to program my own LCD screen to display the percentage?
im trying to cut down my power bill because of my power hungry PC. would this power a PC for more than 2 hours?
What can i use for a small battery? (Lifepo4 12V 8Ah)

I have the aili monitor. When I need to charge my battery do i charge through the shunt or the battery itself?
Can a tablet or a laptop be used as a monitor. I don't have a cell phone.
How can I connect 2 lithium batteries?
You’ll need 2 shunts
2:05 I think its not possible to get shocked with a 12V battery right? Because V=IR and skin is 10000ohms then max current is around 1mA which is not even perceptible.
how you see your battery is fully charged?
Can this be used in a 24v system?
For the Victron SmartPlug Shunt, yes. Specs say it’s good for 6.5v to 70vDC
good video thank you
No problem!
Good video.
Does this work if you have 2 batteries connected?
If they are connected in parallel yes. You would just set the battery capacity to 200 Ah instead of 100 Ah etc
How do I know the battery is 100% before the monitor is connected?
What if I have six batteries connected together?
Usually you'll have a negative and positive end coming out to supply whatever load you have. Put the shunt there. Add up the AH for all the batteries and plug it in.
I wish that made 12v 200mah in that mini size.
Why are you waving those positive leads just above the negative battery post!
You don't want to get shocked ??? and just how do you get shocked with a 12 volt battery ???
unless your hands are wet, and you're doing something stupid, you will not be shocked by a low voltage DC battery.... also, how sad is it to see, a single incandescent globe along with the inefficiency of a big inverter rendering your big expensive 100Ah lithium battery/inverter system useless in about 24 hours!!!

It was for demonstration purposes
I don't have a phone. I won't buy this.
You have used the worst battery on the market
Bad product! Open your eyes!
What is bad?
Yeah, tell us what makes this a "Bad Product". My eyes ARE open and I must be missing what you're seeing.
Maby he is talking about battery :) but shunt is best @@MrTommy001
