I turned the MP3k back on and it did eventually begin to ramp down, however my cells were drifting apart pretty significantly, two around 3.53 and the other two down in the 3.4 range and dropping. ...

And to test powered up, you need to have your battery + and - connected as well   Just to make sure I understand this, the Alt +/- AND the battery (sense?) +/- need to both be wired up for...

thanks. PBF is set to 1 and WS500 does not read engine RPM. So if PBF needs tach data, then this could well be the smoking gun What was odd was, the system has worked well for a month of crui...

Hi, did you move the current sensor to the alt shunt?

Sorry, I tried to format the above for best readability, but it seems some of the styling did not take :(

Hello,  Today I updated my REC ABMS to 2.8 software.  At the time, my pack was measuring around 72% (3.25v per cell), and had not been recharging.  After the upgrade, the pack was reading 50% (Th...

Awesome, I can take it off of my Todo list :)

That was a typo.  The REC Active BMS is a standalone unit and if it were to be installed in a parallel arrangement the two active balancers will fight each other.  For a redundant system you can go...

I\'m very interested in this thread. For redundancy and resilience reasons I\'d like to run with two independent 4 cell packs on my boat. If I were to build it with two REC Active BMSs, a Cerbo GX,...

Yes, something is definitely limiting Field to 31%.. Could be the PBF, Pull back Factor, is this set to 0?   If not, then you have to setup everything so the WS500 reads the correct R...

Update: I received an updated 2.8 firmware for ABMS from Tine today, and it included a 2.8 manual which contains the updated diagram, which solves this all for me :)   Cheers

Hmm.. I read this, did the math, and double checked my settings but I still do not understand why it is not recharging. In order to trigger a charge, I have to set the  \"END of charging voltage hy...

Hello, Today I went to wire up my pre-charge module and noticed that the diagram in the latest REC ABMS Manual, as well as the lates REC Pre-Charge Module manual, illustrate what appears to be a...

Good morning! I am using a customized version of #7. The exit amps settings in #7 dont work for me. Anyway, I do believe some parameter is limiting Field to 31%. Not temps. I am using a PBF of 1...

Check you have the Firefly \"configuration file\" profile loaded.  You can download it here:  https://www.wakespeed.com/product/ws500-advanced-alternator-regulator/#wc-tab-title-support Also, ch...

The Q series has firmware that is keyed to the serial number, so you just need to send in your request to REC, along with your serial number and they will get you an update. It can be installed ...

Thanks, Firefly bats so no BMS. Dual engine. Controlling WS500 flashing Green Acceptance, slave WS500 orange flashing.

Does anyone know where I can get an updated software version for the REC Q unit that has this parameter option in it?  I have the 2.6 software of the BMS and the 1.6 version for the Wi-fi module bu...

I am having the same issue. Victron says I need ABMS firmware version  2.7 for full integration with the WS500 and mine is currently 2.6. All I find in downloads at REC is the manuals. I did get th...

In my opinion, you can allow the BMS to push out the battery temp but I would hardwire the current sensor in parallel with your Smart Shunt(just use a couple of ring connectors on the power wire lu...

Yes, the USB will power up the WS500 but it will go into alarm after 30 seconds on a low voltage condition.  If you have our WS500 config tool, it should notice this and ask if you want to put the ...

David, I think this post may help with your questions. https://www.offgridsoftwaresolutions.com/ws500-user-forum/topic/rec-abms-not-recharging-after-reaching-full-charge/#postid-1153 Cheer...

This summer we did some testing on a firmware tweak that would provide better control at the very top of the charging range using the larger SI-Q series BMS.  I put together a draft charge profile ...

75.9% today, 13.27 volts, still no charging occurring ;( Also looks like I forgot to mention I am on 30A shore power at the moment.  MP3k is set to 100A charge limit

As I get closer to wiring this up, I wanted to confirm my understanding on charge control is correct. ABMS is at stock configuration: cell over-voltage switch-off per cell 3.85 V over-vo...

I found this video from wakespeed where they show only plugging in the USB cable.  This worked for me!  

For the record, I did experience this a little bit after my upgrade, some of the values I entered would get submitted with the decimal in the wrong place, or omitted entirely.  It did not persist t...

I am trying to power on my WS500 to check firmware version, upgrade, and configure via my android.   I have bound the Ignition Wire (Brown) and Alternator Positive (Red) to +12v Alter...

ahoy! I convinced myself that the balmar 618 was a waste of time and received the WS500 kit today.  I\'ve got a few questions around operating it in tandem with the REC BMS. From reading the ...

Hello, My system has been setup for a few days, and it is either not re-entering charge mode, or I dont know how to determine when it should be (i.e. an SOC level, a voltage level, etc.)  Most like...

It could be one of several things !)  If the LED is flashing orange, your BMS is controlling it and you will need to check your cell voltages and temperatures to see what is pulling it back 2...

Hi, Batteries were at 50% leaving the anchorage but max output from dual big alternators was 95A. Regulators started in bulk then later to accept but output low and V around 27V. V slowly climbe...

With the WiFi module (1.6) and the REC-BMS (2.8) configured, I have a couple of questions My understanding is the REC-BMS checks the battery voltage and requests charging from the SI. I have inc...

I started from scratch to make sure I have all the right software running in the BMS and WiFi. reloaded the BMS firmware hardware reset of the WiFi module reconfigure WiFi module inst...

I set up a Q Series BMS last night using 2.8 firmware to start testing to see if I can duplicate these out of range numbers you are getting. I had an old WiFi module, so I upgraded it to 1.6 but...

I am going to set up our demo board with a Q Series today (I only have an Active and Master/Slave up now) and will see if I can replicate your issues.  I have pinged REC tech support to see if they...

Sometimes the answer is right in front of you and you can\'t see it. From that same forum post: \"Some of the devices are controlled by applying ground so ground is connected to fused input a...

Backdated the firmware by removing the SD card, deleting the old file versions, reinstalling the card, and restarting the WiFi module. I\'ve attached a screen shot showing the software version. ...

Here is the DB9 pinout from the BMS.  Just grab a DB9 connector, a 120 ohm resistor and a phone patch cord and you should be able make one. Keep in mind that there are no standard CANBus protoco...

yes, there are files for both hardware 1.2 and 2.0.  Maybe you grabbed the wrong  HW version files.  Try again with the hw2.0 files And just in case I am posting 1.5.7 files here, in case you ne...
