How to disconnect battery in an emergency when using Lynx power system?

I am planning a setup to use a Lynx Distributor for batter input, then Lynx Shunt, and another Lynx Distributor to the loads. Management will be a Cerbo.

Question: In such a configuration what are people doing for emergency battery disconnect switching?

Will the Fuse LEDs on Lynx Distributor illuminate without the 4-pin cable supplied with unit?

Trying to use the Lynx Distributor (and Power In) without the Lynx Ion Shunt or BMS (using BYD batteries). I had assumed the Fuse LEDs would illuminate with a working fuse in place and powered, however a line on the old Victron Live page for DC Distribution Systems suggests that this small data cable is used to power the LEDs (rather than taking power from the busbar itself). I cannot get the LEDs to illuminate - are the LEDs useless unless using the Lynx Shunt? Because Lynx Shunt uses CANbus, it cannot be used in conjunction with BYD on a CCGX (though I think VGX would support it).

Venus Gx with BMV-712smart - Which is the data source?

Greetings All. I'm just diving into this world and I'm having difficulting understanding the relationship between the BMV and the VenusGx. Specifically, If I'm using the Lynx Shunt to provide input to the VenusGX, does the BMV receive the battery data from the Venus via the VE.Direct link, without the need for a second shunt (the one that comes with the BMV)?

Or, is the BMV a transmit device only, which would make the Lynx Shunt input to the VenusGX redundant and unnecessary?

Thanks in advance for any insight you can provide.

Cable Lengths When Wiring Each Battery to Lynx Distributor

I’m considering wiring each of my 4 LIFPO batteries to the Lynx Distributor separately. I’m wondering if anyone with experience has thoughts on the following:

1) Do the wires to each battery need to each be the exact same length? I know it’s important in traditional parallel wiring for wire lengths to be equal, but haven’t seen anything on this when wiring directly to the Distributor.

2) Is battery balancing impacted with direct wiring as compared to traditional parallel wiring each of the batteries together with diagonal positive and negative terminals wired to the Lynx Distributor?

3) any thoughts on cost efficiencies of wiring each battery directly to the Lynx Distributor? Smaller wires, but more fuses, etc.

Lifepo4 capacity and lynx shunt calibration

Hello from sunny south florida,

I an Electrician and my company assigned me that task of building out a camper van for a client. After some research I ended up using a multiplus 12/3000 with a CCGX, the lynx shunt 1000a, a 45amp mppt solar charger with ~250w worth of solar panels on top of the van(I wanted more panels but customer wanted more storage)and 2 renogy 170Ah lifepo4 batteries in parallel, and an alternator charger. The equipment seems to be operating as it should with the exception 1 thing that just popped up last night. The load on the system is roughly 20w to power the ccgx and the cellular internet (according to my CCGX).



with the rating of the batteries at 2175w each i estimated the system should run for ~200hrs +/-with no charge, ive been monitor the vehicle through VRM and it all has checked out until yesterday..the customer has had the van parked not in use all of last week. We had good weather all week with the exception of friday when it was cloudy all day and the solar didnt produce much.

To get to the point though the batteries died after ~ only 24-32hrs of no input am i mis-calculating something here or do i need to look into the current calibration of the system?

BMV Bug? - BMV vs Lynx Shunt in wild disagreement of SOC

Screen Shot 2020-09-20 at 5.11.12 AM.pngScreen Shot 2020-09-20 at 5.11.27 AM.pngScreen Shot 2020-09-20 at 5.14.16 AM.pngScreen Shot 2020-09-20 at 5.14.51 AM.pngHi,

I've been running the BMV for a few years and have ~60 automatic sync. I also have been running the lynx shunt for a while with about 10 automatic syncs. I've confirmed the settings between the two and interestingly they are wildly off between them. I've tried a couple of things and have some examples below. I've set up a rPI + grafana/influxDB to capture data at higher resolution than VRM portal so I can look at the data in different ways.

The large vertical jumps on the Battery SOC is from me forcing the SOC to match the Lynx to see how the slopes match up. The interesting things here is that the Ah Consumed match up pretty close with the Lynx SOC but not even close on the BMV.

With the the value right now, you can see I've consumed about 86Ah of battery power (86/1200), or about 7% based on the BMV stat. This is almost perfect with the Lynx showing 92% SOC, but the BMV shows 84% SOC. I then forced the BMV to be 92% a few min ago to see if this lines up.

While the Lynx CANBUS updates are slower than the BMV, there might be a bug with the BMV?

Grafana screenshots and BMV + Lynx settings attached. Am I missing something here?

Thank you!!

Lynx shunt not calibrating to lithium batteries





I have my lynx shunt calibrated exactly the same as my BMW and it’s seen about 5 full charges whereas the BMV has seen 60. The voltage is the same as well as the draw, however, the lynx seems to think that my SOC is 70% and based on the voltage it’s more like 40%, BMV is correct. Ideas?

Lynx Shunt 1000 with Lynx Distributor 1000


I've recently design a setup with 4 x 12V 200A Smart LiFePO4s in parallel connected directly to the Lynx Shunt 1000. The Lynx shunt is then coupled with a Lynx DC Distributor 1000 on its RHS. Connected to the Lynx DC Distributor is the Victron 12V 5kVA Quattro Inverter and DC loads.

Is it ok to connect the batteries directly to the Lynx Shunt 1000 and the fuse within the shunt can be used as circuit protection for the batteries?

Lynx Shunt VE.Can Transmit Frequency?

Is it possible to adjust the transmit frequency of the current data (PGN 0x1F214 / 125708) from the Lynx VE.Can shunt? In our system it only seems to broadcast about once every 1.5 seconds. We're trying to feed the data via CAN to an alternator regulator and there's too much latency for the control to stabilize.

More generally, is there any documentation available for the Lynx Shunt VE.Can standalone? All I can find is the manual for the Lynx Ion w/ Shunt, which seems quite a bit different.

BMV using lynx shunt and Lynx shunt


I’ve installed the lynx shunt and made my system use it vs my BMV. I then attaced the BMV shunt PCB to the lynx shunt and are sure the BMV settings has 1000A for the shunt size. I need to have the gauge display, however, I noticed the BMV is becoming more inaccurate as time goes on and it used to be right on the money. What is the voltage for the lynx shunt, the BMV was 50mv. Barring this set up, should I put another shunt in-line for the BMV? What are others doing?

Battery Temperature monitoring with Lynx Shunt

I am installing an all Victron system in a vehicle consisting of 12V lithium batteries, Lynx distribution, Lynx shunt, Ve.Bus BMS, Multiplus, smart battery protects, MPPT, BuckBoost, Digital Multi Control, CCGX and am trying to determine how the battery temperature should be measured in order to prevent charging below 5 degrees.

I have a temperature sensor supplied with the Multiplus and what looks like a temperature sensor supplied with the Lynx shunt. I can't find any info for the Lynx shunt sensor - does it connect to negative or positive as the BMV? The only thing I found was "Please don’t use the 2-pin terminal block on the Lynx-shunt" from If this means the sensor why is it supplied?

The CCGX manual states that DVCC should be enabled when the system is "standard" and there are "intelligent batteries" installed. In this case are the other temperature sensors redundant?

Any clarification appreciated.

Lynx Power In left or right of Lynx Shunt?

I have to install two 48V 2600Ah parallel OPvZ battery banks to a Lynx Shunt so I will use a Lynx Power-In to connect these batteries to the Lynx Shunt.

As far as I know, you are supposed to connect the batteries to the left side of the Lynx Shunt and the chargers + load (via a Lynx Distributor) to the right side.

However, in my setup it would be more convenient to swap both sides. So is it mandatory to connect the batteries at the left side of the Shunt and the loads/chargers at the right side or can I swap both sides?

Thanks a lot for a quick reply!

Is it ok to use an ANL fuse of 400A instead of the CNN?

My system has external fuses and if there is nothing else involved for the fuse on the shunt then to blow when overcurrent is flowing between battery and units then i in reality could just connect a piece of copper.

BMV & SmartSolar Streetlight to warm battery box

Hi, I have a 190ah LFP battery going in to an ammo can which will be in my truck bed. I'd like to heat the box using small ~25w heat strip(s) when the battery is too cold to charge, but only if it was going to charge in the first place.

What I mean by that, is that if it's the middle of the night and below freezing, don't bother because there's no sun to charge with anyway. Similarly, if I have a foot of snow on the panels and it's freezing outside, don't bother because the panels might not even produce enough voltage to initiate a charge cycle.

I was thinking some combination of the street light function, load ouput, and BMV low temperature relay setting could accomplish this. Likely easily with the ability to invert the streetlight functionality but I do not think that's possible from my research. Maybe some NC relay that the streetlight triggers when it'd normally be operating an actual streetlight (night?)

Any ideas appreciated!
