Hi Ben Screen shots as requested. Thanks for any help you can offer🤞🤞🤞👍

Having read through the various documents I would like to check my understanding before I make the install. I have no NMEA2000 network so the only devices will be the WS500 and the Cerbo GX connect...

Check under dvcc, max amp setting.  Post screenshots from this settings.

Hi All I am in the process of setting up a lithium batter system on my boat, I have the various bits working. The Mutiplus will charge at 120A but when the Cerbo is connected it is cutting it...

This is an A-BMS 12V installation? Anyhow, it your 100% sure the senswires are correct then it sounds like your BMS is broken.

Hi I hope someone can help with this error code on a new installation. So far i have checked All sense wires -correct checked fuses . replaced the blown fuse on battery sense wire #4 ...

Thanks for posting this as I was just going to post a message about this. Previously, we had to reach out to REC directly to obtain a firmware update specific to our serial number. However I\'ve no...

About a week ago I started receiving an error message on my REC Active BMS Wi-Fi portal when logged in. At the top of my page I see in bold red text “PROBLEM WITH SD CARD, LOGGING IS DISABLED”. I h...

REC has just released a firmware update for the Active BMS that adds a new CAN message and addresses an RS485 bug.  For details and downloads you can visit the REC North America site here:    https...

A connection problem seems unlikely to me - recall that this only occurs in acceptance and float.  In bulk everything looks fine.  I don\'t see how a connection problem would work that way. All ...

Rick, I have the official REC cable.  Will the BMS power on and be responsive if the only connection is the serial cable?  My battery pack isn\'t quite ready but I want to test the BMS using the...

I grabbed this  page snip from page 13 of the Active BMS manual. Manuals are available here:    https://rec-bms-na.com/downloads/  

Hello, I recently bought a WS-500 here and, after installing it on my sailing yacht, it has been working very well. But I have two questions where I would like to ask for support. Unfortunately ...

Just to close the loop, I trimmed the sense wires and ran them away from high current lines. I also cleaned the contact surface of the shunt and re-terminated. No sign of this issue since. Safe to ...

Quote from Ben on January 10, 2023, 7:54 pm This looks strange for me, especially how the voltage can drop from 14.4V back to 13.0V in seconds. Looks like a connection problem in the battery ca...

This looks strange for me, especially how the voltage can drop from 14.4V back to 13.0V in seconds. Looks like a connection problem in the battery cables. Can you add all regulator wires in t...

I installed a WS500 last fall and am seeing some strange behavior.  My setup is a a 320A Leece-Neville alternator, 4x Rolls AGM batteries as a house bank, and a single Rolls AGM as a starting batte...

I forgot about the Firmware tab. No way to set the date. In looking at the log, it is not clear on the unit of measure for each sample.

The Active BMS and Master both have a Real Time Clock(RTC) but the SI-Q series standalone does not. Time can be set in the Firmware tab of the WiFi module.  From the manual Firmware tab is us...

I don\'t see anyway to set the date and time. In looking at the log file, the date and time fields are empty.

What are the minimum connections need to verify operation and communicate via serial interface using the REC USB to RS485 cable?

yes, but REC was closed over the holidays for more than 2 weeks.  It normally only takes a few days.  I would expect to see it early next week

Both Trond and Ben make a very good point.  To switch an alternator is usually as easy as finding the brush wire that goes to the diode bridge and moving it to ground instead.  Your other brush the...

I agree with Trond Arvid. I prefer also to have p=type regulated alternator. I see more advantage for this, for different other reasons also. Most off the time easy to modify the alternator.

@rick_tech_support Rick, I sent the info you requested a couple of weeks ago. Did it find its way to the right person?

You will probably find that is more easy convert the alternator insted. From negative regulated alternator over to positive.  

Yes it is possible but Wakespeed does not share this information freely as they say incorrect configuration can cause serious damage.  If you contact them directly they may be able to help.

So I have 2 WS500\'s with Ptype harnesses I used with Balmar 621 alternators on my old boat, moving to a new boat and looking at different alternator options and having issues trying to get p type ...

Rick, You rock! Thanks! Stefano

Hey Stefano, Not quite sure what is happening with the new company but we have been trying to give them some constructive feedback and fortunately we have a great bunch of people with WS500 expe...

Thanks Ben, This is helpful indeed. Can you please point me to the full manual, if available to the public? I imagine that this OS is not proprietary, but it is new to me and a pointer to where ...

Hello Steven M, The manual you use is a short version, and indeed not really clear. I have send a comment to Wakespeed to make this chapter more clear. copied from full manual: \"\"$CPA...

The comma after the custom table 7 or 8 is not required.  If you have a PC and our WS500 config tool you can upload your current parameters and verify they were correctly posted.  Also, when you ar...

Rick, thank you again for your helpful responses. I think you might be on to something with the induced-current idea, as the shunt sense wires are coiled near the positive power cable where a lot o...

The first place to start is with your wiring.  The current shunt sense wire measures a very low milli-volt signal and is susceptible to outside interference.  Make sure the wires are not near or wo...

I recently installed my first WS500 in my boat with REC-BMS and Victron integration and a dedicated alternator shunt to measure output. It\'s awesome and solved some longstanding charging issues in...

Bi Ben, Thanks for taking a look.  Here is a screen shot with both the text file and the manual with the commas. The same syntax discrepancy is present within the manual\'s Lifeline .txt example...

Your posted example is correct. I dont see, your mention comma in the manual. As reminder, you are programming profile 7,    7  is not the first parameter. Dont forget to set the dipswitch...

That fixed it. Thank you!!!!

Ben is right, you will not get the VE.bus BMS V2 to sync to the WS500, as it does not send CAN bus data like REC BMS does. You will have to setup the WS500 with regular Lifepo4 charge profile. ...
