sure, I will look for it and send you the file.  Please keep in mind this a beta release and should be treated accordingly.

That would be appreciated, I know I did not buy it from you, I have sent a technical query message with email. I will then get it installed if I get chance before winter.

If you need a copy of the BETA let me know and I will get you a copy for testing if you like,. Rick

Thanks for the update, I will hang on as things look good.

I installed a 2.5.1 beta back at the beginning of the summer.  The behavior of that version in acceptance mode is 'correct' - smooth and just what I'd expect.  In float mode the behavior ...

Welcome to our User forum :) I have replied in blue below your questions: 1) Is there conter-recommendation or issue to using REC for parallel connectivity in general or at 48V, in particular? My...

@Ben @Bill good that it works. But looks like strange settings you made. Not sure or it is easy for you to do a test, or the "setcoil +". Or the "setcoil-" is the one that gives the trigger signa...

@Bill I know this switch, but have a look at the ml7713!!!

@Ben Here are the important specs.

@Ben This is the switch that I using. It is highly recommended by the electrical engineer that is overseeing my design. It also meets all of the required certifications for my MARINE application, w...

@Rick Thanks, I'll try that.

Bill, you are correct, the Android app offer a good Q&A approach and will do 90% of customers.  If you really want to dig into each parameter and log data, then we have a Windows app for t...

normalized simply means that the system parameters are all based on a 12V system, with 12V being equal to one. So a 24V system would be a 2 (2 x 1) A 32 V system would be 2.667

Its on the module under a steel slip clip.  Just remove the 4 screws on the case.  There should be a couple of posts on it if you search, but basically you just remove it, reformat it wit...

I used this figure from the REC ABMS manual on page 8 to help me.

I used the info from both of you. If you look at this drawing, you will see that: (1) Jumpered pins 3 and 4 on the Pre-Charge module, but am wondering if that is only required to use the active ba...

It looks like you are missing a jumper between pins 3 and 4 for your pack power.  I would try that first.

Hello Bill, System design is a choice from components. You didnt mention which ML relay you use. Looks like the ML 7700.  I didnt install this with the REC prechargeV3. But install them with...

Hi Peter, thanks for the feedback!

Dear All, I am wiring up a Blue Sea ML-RBS Remote Battery Switch with Manual Control - 12V DC 500A contactor with a REC-ABMS as recommened by my marine electrician. I have tested the contactor and...

Thanks, this is very good example. I will go back to the WS App and put in my values and then post them here for comparison and to see if I did it correctly.

I logged in to the REC BMS WiFi module today and suddenly saw a "PROBLEM WITH SD CARD, LOGGING IS DISABLED" message. SD Card info under the "Settings" tab shows this:       Wh...

I will try and illustrate this with an example. I have a battery bank of 750Ah. The maximum charge rate for my batteries is listed as 0.2C, so 0.2 x 750 = 150A. My battery bank is 750 ÷ 50...

I have been able to fully configure my WS500 using the Wakespeed app on my Android phone prior to installation. However, I habe not yet got the unit installed to test it.

another post to push this topic to the top of the list

I see that there are severval ways to communicate with the WS500. Can I assume that using the WS app on an Android will give me full access and no need to even bother with any of the other tools on...

There is a new 2.5.1 beta release of the WS500 that may help.  I havent had a chance to try it myself but I will send it via email for you to test.

@John Yes, the if you download the app there is no need for the thumb drive

Does soemone has a working setup with the REC2Q BMS and the WS500? Can you share your settings?   I dont get the communication established with the rec 2Q BMS.First time I installed this BM...

I guess my writting is not very clear. My question about the software is:  Can I download it off the web, or do I have to buy it?

Would anyone know what was the reasoning behind using RS485 connectors on the REC BMS vs. a RJ45? Also, could I cut off the RS485 and replace it with a RJ45?  This would make such a cleaner i...
