Hey Ben, thanks for the reply. Here is a screenshot of my REC home page. This is a 24V start battery, so 2x13.36=26.72. My SOCH = 0.05. Cell difference is typically 3-7mV. I have about 0.3A of drai...
Hi everyone, I've set up and have been using successfully for 1 1/2 years with no issues a REC Q BMS (firmware 1Q-4000+, manual rev 2.9.0 Jan 2023) for my 24V CALB 230 cells LiFePO4 battery bank (...
Earlier I had asked Grok to compare the 2.6.0 docs to the 2.6.1 version wrt to changes realated to REC BMS. I should have posted that convo as well: Changes to Support for REC-BMS in Wakespe...
If you get a chance to review the above, let me know if you find any errors that Grok has made. Thanks!
Continuing with Grok, I asked about DVCC support changes, and support for CerboGX. Changes and Improvements to VE DVCC Integration in Wakespeed WS500/WS500-Pro Firmware v2.6.1 VE DVCC (Victron En...
I asked Grok to: create a table of changes from 2.6.0 to 2.6.1 firmware version. I am still checking to see if Grok's answers are correct. Changes from Wakespeed WS500/WS500-Pro Firmware v2....
I just noticed that the Wakespeed has released new FW: 2.6.1 along with an update to their Comm and config docs. There is also an update to the Android WS app.
Ok, I'm glad that someone else is seeing the same thing. Where did you see the text "Add Battery charge request info"? In some release notes or elsewhere?
@Peter That's my understanding as well, and my set up.
Just noticed that in the House Batt (REC-BMS Q Series BMS) Parameters page, "Reqests Charing always shows "No" even when the WS-500 is charging the battery and the volatge is lower. Is this...
I can't seem to figure out how to remove the inverter and AC loads icons from my DC only engine alternator system. I'm sure I'm missings some setting somewhere. Anyone else figure this out w...
The WS-500 2.6.1-January f/w seems to be the ticket
I'm using 3 as well. Everything seems to be working. Thanks!
Reach out to matthew@dragonflyenergy.com for the latest firmware update. That way, you will get the latest version, which I believe is the January build.
I've updated to the 2.6.1 January build and can now see field drive on my Cerbo.
Based upon this from the manual, I think that I should use option "3."
On a LiFePO4 battery system that incorporates a Cerbo GX, Wakespeed WS-500 and the REC-BMS which Alternate CAN / BMS protocol are people using?
- Cerbo GX running latest sw - WS-500 running f/w 2.6.0 - WS-500 charging at 153 amps, but field drive reporting shows "0%" - Does anyone know if this is a WS-500 or Cerbo GX issue? - I h...
The question in this thread does not match the thread title... What is the correct value to use for LiFePO4 cells??? @Ben recommneds 1.0, but I believe that I've seen othe...
I used Rick's cheat sheet along with recommendations from Ben.
@Rick Admin , As I am considering my options and reviewing the 2Q details, I also need to ensure that they are compatiable with my WakeSpeed WS-500 regulators and will work seemlessly with the Cer...
Hi Rick, Thanks so much for your quick response! I thought I’d post this in the forum here, just in case others have similar questions. I’ll definitely take a look at the ...
@Richard Thanks! I am reviewing the video. Great suggestion.
Hello all, Any news on a SW update for the Q-BMS devices? I have a 9M managing two Q-BMS 4P8S house batteries. I also have a single Q-BMS for my propulsion engine start battery. I am ...
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.
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...
This is good feedback. Thanks! I will login and see if the fast ramp is/is not disabled.
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...
@Rick Thanks for this info. I thought that I had mis-configured something. Is the workaround to use the WS-500 with DVCC turned off until 2.6.1 is released?
@Jonny I've been away from my boat for a few months, but am about to get into settling in my Wakespeed 500-Victron-REC-BMS configurations and set up. I will collect as much data that I can a...
Hello All, What charging precedence strategy are you using with your REC-BMS-controlled-Victron-Energy-LiFePO4 marine battery system? I have Multiplus-IIs, Wakespeed WS-500, MPPT solar char...
I would like to access my REC Wifi module on my boat. I have Starlink and have been told that there because of how Starlink assigns IP addresses using CGNAT that I will need to use some other techn...
@nworker becasue there is no real time clock (RTC) on the Q Series, my graphs simply show an incrementing integer sequence along the X-axis.
Can someone explain how the passive balancing alogrithm works on the the REC Q BMS. When you reach the balancing start voltage, in this example 3.45v, does the REC balance one cell at a time by dra...
@Ben I've done some additonal reading and in your experience should the BMIN BVOL values be the same for active vs. passive balancing? Perhpas I am thinking about this the wrong way,...
@Rance Thanks very much for your reply. My set is working pretty well, but I am still working through some issues. Sometimes the field strength bounces between 0 and 2%, when it should be charging...
Guys, thanks for all of the help. I have been moving my settings to match the recommended values from this thread. I have one question regarding float voltages. While away from my boat, I ha...
Was the data file sent over to Al at Wakespeed. I'm have similar issues.
