for what it's worth, I replaced my switch with a bigger one that is mounted in a watertight box and labeled the hell out of it.

In a marine environment anything is possible with the humid salt laden air.  I would remove and inspect the harness and connector pins

@Rick could the bad connection be in the plug/socket arrangement in the bottom of the BMS?????

Thats great news Michael, pins are crimped on the harness I have here in the office.

@Rick@Tine Andrejasic  Thanks Rick, the update that Tine has supplied has resolved the issue, thanks to you both.I will check the connections in the top of the cells, they are under a clear p...

I think I have a reasonable explanation for your error.  When the Active BMS first powers up it does some tests and one is to drive the active balancer which puts a large load on you cell tap ...

What do you guys and gals do with the tiny tiny on-off switch on the BMS harness. Replace with human size? OR somehow install. If you install i'd love to see how. I am tempted to just leave it hid...

Hey Mike, Thanks, I appreciate that.  I havent heard from Tine on this one but I'll reach out to see if I can get to the bottom of it.

Hi Rick, just to keep you in the loop, Tine has sent me a firmware update, I will give this a go(unfortunately I don't think I will get to the boat till the weekend), I will update the forum on the...

Hi everyone,I've been monitoring this behavior and noticed the following:The BMS only switches to float mode once the set float voltage is reached or drops below that threshold. With a Victron syst...

@Rick Hi Rick, just back from the boat, and I can confirm that the cell voltages are pretty much what the BMS is reporting, so slightly at a loss where I go from here apart from sending the unit ba...

Have you ried connecting directly to the slave with the Wifi Module?

As you can see it seems that the BMS is seeing all the correct numbers and forwarding them onto the display, so slightly confused why the BMS is erroring out as I would have thought the numbers wer...

@Rick I will check the measured voltages compared to the screen shots 

You may want to DM Rick Bell, the owner for sw/firmware update issues. Send an email to the ogm support email address. support@ogm-energy.com Please report back what you learn. I too have a 9M con...

ok Mike, with this additional information it changes the equation.  An error 10 is usually a serious error on a failed system.  When you get back please verify the error code and all cell...

Hi Rick Thanks for this, I will give all of this a go, but I am off the boat now. It's interesting that you are indicating that it could be the cell tap wires, the display on the BMS is showing t...

Hey Michael, An error 10 is not good.  It usually indicates a short circuit or blown fuses in the BMS.  This can be caused by removing a cell tap wire while the harness is connected or a...

Hello all, happy Easter, I am getting the same error code, error 10, on restarting my system having had it turned off for the winter. the system has been running for the last couple of years w...

This is good feedback. Thanks! I will login and see if the fast ramp is/is not disabled.

Hi @Bill Caswell . I finally got time to investigate this further after getting a response from the AI. Here is the answer I got "There is also a feature on the Alternator Tab (Expert mode) to togg...

@Trond Røsvik that was my understanding of DVCC as well.  If I still had the AGM batteries and only a smart shunt this wouldn't stand a chance.

Arco says "victron follow" needs to be anabled for DVCC to work. But I found that this only works when you have an Victron Lynx Smart NG BMS in the system.   So in my opinion its not tr...

I just got to the boat and can confirm that it still doesn't follow DVCC when Setup at 250k on the other canbus from the REC it'll show up as an alternator, but doesn't recieve any useful informati...

"Does it follow DVCC now as well?" No, I have not got DVCC to work, not sure why. Perhaps it needs to be set to "Victron follow".  but that only works if you have an Lynx Smart BMS NG as well...

@Trond Røsvik does it follow DVCC now as well?  Suppose I want to leave my REC on can2 @500k and put the Zeus on Can 1 at 250k as a VICTRON follower.  Will this work now?

I think I found the problem myself. In my system, there is 7 batteri monitors: 4 Batteries, then there are also 2 pcs MPPT and 1 PCS Multiplus, but the Cerbo sends these data as an battery m...

Ever since installing the Zeus I have been having issues with NMEA2000 data becoming corrupted and making the whole system crash.  I have many battery monitors, charger info, 5 tanks etc trans...

I have tested the 1.24 FW and App V 2.0.11 that comes with it. The Alternator volt and current now shows up in the Cerbo (not battery volt and current like before). The only drawback is that it s...

Hey Stephano, The way 1Wire networks work is they use the network ID number as the reference so once you thermo cycle them you can sort them by cell #, as the ID number is not usually written on t...

I am using three Blue Sea Systems mini bus bars to connect 8 sensors to an ABMS. I have tested up to two on the bench, and they show properly in the interface. Short of using some heat or cold to t...

The good support folks at Dragonfly have sent me the 2.6.1 sw version to try. How has it been working for others?

Hello All, I am just seeing this thread. Is there support for the REC Q BMS and the REC Master? I have a REC Master managing two REC Q BMS units for my house battery. And another REC Q for my main...

Hello, can you help me? I have a Master 9M unit with 2 pcs of slave units (2Q) and a WiFi module. I have no issues with Master-Slave communication (no beeps, no errors), and readings from the sla...
