Wakespeed firmware 2.5.0 is being released this week; and has some improvements - but there still might be work needed on the REC side for its requests, as well as refinements how the REC BMS is co...

Thanks for the feedback guys.  It is looking more like everyone does indeed have the 1.2 release version boards.

I believe i am experiencing something like this as well.... ? FYI. I have ABMS, wifi, LCD, Balmar XT170, WS500, Cerbo GX, Victron Multi\'s and Victron MPPT x 4 all CAN or VE connected. With t...

I too have just updated from HW:1.0  SW:1.5.1 using the 1.2 files now says HW:1.2  SW: 1.5.8 All looks ok.

He is not active on this forum so email is best tine@rec-bms.com

I see. Do I reach out to Tine directly over the forums or email?

In another post somewhere Tine mentioned that they can custom configure your spare opto output to do that for you for about 25 Euro as I recall.  This is not a new feature.

When there is no battery voltage they do a reset every 30 seconds or so.  If you need it to stay on you can put 12V across the battery +- wires or put it into \"Config\" mode with a command.  You\'...

That makes sense. However I have the Q BMS. My understanding is there is some firmware version that lets me control an external relay and have it turn off when nearing low voltage, before the main ...

That\'s good news and tends to support my comment about you likely having the 1.2HW and the text was just not changed in the original build. You might want to run your electronics off of a separ...

I completed the update using the HW1.2 file and it worked. I can\'t tell that anything is different, but the WiFi module still works and shows the new firmware version. The LCD still is flaky to...

Hi there, Installing my WS500 and a few questions:   firstly, while configuring the unit while it\'s not plugged into anything but the USB cable, it works fine for around 30 secs to...

Im interested in this too. I have an ABMS, LCD & Wifi. (bought direct from REC, early) I have just updated to 1.5.1 and it states HW:1.0 - all seems OK. But if it is really HW:1.0 can ...

Thanks Rick, that sounds good to me. I super appreciate how you handle things. My system is currently only on when I am working on it, so I can definitely do without the module for a few days. I...

Hey Peter, Let\'s see how Eran makes out and if needed, we will extend the same offer to you. Thanks for the feedback, Rick

Hi Rick, I’m interested in this topic as I have the Rec WiFi module connected to the REC-BMS Q.  The Wifi module shows up in the REC web app as HW: 1.0 and SW: 1.2.  I purchased these parts and ...

Eran, From what I understand here is that 1.0 uses different GPIO pins off of the ESP32.  This means that if you were to install the update on a 1.0 board it would try to use the wrong pins for ...

Thank you for the reply. I am confused then, how come I have a module that says HW 1.0? I purchased it through Offgrid Software Solutions, nothing was mentioned about it being a prototype. If it...

WiFi HW 1.0 is not upgradable with HW 1.2 and 2.0 since this were only evaluation modules - prototypes. We have changed the HW later for faster production and improved the hardware for better opera...

Tine, Can you please clarify here. The customer has already upgraded his rev 1.0 HW board to FW 1.5.1. Please clarify what you mean in your last reply 1.0 was only beta, not upgradable ...

Hm, that is weird. I could go ahead with the update but I wouldn\'t want to brick anything or make my life harder. Would rather hear back that I should upgrade even though it says HW:1.0 at this po...

I have just recieved the new firmware from rec bms.

Hi Ben   It looks very nice. Am I understanding it right, that the new CFVC is a user configurable parameter? Is this firmware released?

On a couple off bms I did a firmware update this year before update HW 1.0 SW1.4.1 After update HW 1.2 SW 1.5.3 1.5.3 was the latest firmware at that time. For me it looks strange that ...

Hello Sten, Below is just new information from REC. Some off my suggestions are available in the new firmware 2.8. see below information from REC. ========================== Newest f...

Hello My Wifi module is showing HW:1.0 SW:1.5.1 at the bottom of the firmware upgrade screen. Does that mean I have a beta? I do experience issues with the LCD screen, it is unreliable and so...

I now very well that the hysterese factor is not programable, but I made it that way to see how diferent factors inflict on the calculation. The \" Low end of charge\" is the CVL calculation  \"...

Hello Sten, My posted sheet is part from a bigger sheet.  The bigger sheet make this calculation also automatic. When I have time, I will check what went wrong with my posted xls, probably wh...

Hi   I have made a spred sheet based on the information in Ben\'s spred sheet. It\'s a dynamic spred sheet where end of charge voltage, end of charge voltage hysterese and the factor ...

Thanks. :)

Hello Sten, zip file just 10k, lets try. see below. (update: the forum system dot allow to upload a zip. the pdf below, is a zip-file, please rename after download to  .zip, and then unzip...

Thanks, I would realy like to see your thoughts about the rec cvl calculation. Maybe you can pack it in a zip file and get under the 10k limit? I\'m not sure a factor at 1 is the right one, b...

CVL is recalculated multiply times, with different formulas in different stage off the charge. If you program the REC parameters, different charge voltage will effect a number off things as desc...

Yes I can but then I have a to high \"float voltage\", so it does not solve the problem. Problem still persist. The factor is still a big problem.

Just change CHIS til some lower value, problem solved?  

Hi   CVL is calculated 4*(CHAR-(CHIS*0.2)) according to the  ABMS manual, but after some calculating the 0.2 factor is more like 0.5. The factor is a problem because it\'s to low. If you...

I\'m currently using a MSI workstation (PC) with Windows 10 64bit. An important note is this laptop only has USB3.0 ports and one USB-C.   What I downloaded from Wakespeed website: ...

So far as I know CVL = (4*CHAR)+.0.1V   When balancing start, CVL is recalculated! And when batteries are full CVL is recalculated again. Above I use the CHAR for \"\"End off charg...

Looking at \'BMS Charge and Discharge Limits\' in VRM I am reading CVL - Charge Voltage Limit (V) as 13.3V. With BMS set as 3.55V end of charge voltage and 0.45V hysteresis CVL is 13.3V. Chan...
