Hey Lure, if you could share a bit of your code or a github link to help others get started, that would be awesome!!

@Bill I am hoping it will be first quarter 2025.
Peter, I will answer your tech questions here 1) WiFi values can be read using HTTP get calls. There is another thread on this forum with info and others who are doing it. You wi...
With all of the recent changes to the WS500 firmware we have decided to sunset this product development. We suggest you use the android tool available from Wakespeed for firmware updates.&nbs...
This is what we got back, which is encouraging and keep in mind that the Master uses firmware that is keyed to the serial #, and has to be requested from engineering. WCIB does not work on Ma...
Hey Bill, I am not sure if the Master supports this new function but will check with engineering and report back.
Bill, I looked over your parameters and in my opinion, they are pushing the limits on both the high and low voltage side. Between 3.5 and 3.7V there is only 1-2% capacity so I would tend to be a bi...
The cable is custom assembed and comes as part of the REC BMS software kit. You can buy it here. https://ogm-energy.com/products/rec-pc-software
Great, glad you got it working. For reference, if you want to move to the VE.CAN port here is a quick video to help setup the BMS and the Cerbo. https://ogm-energy.com/community/ogm-user-for...
Hey Mike, REC is pretty good about sharing this info so by way of this message I have included Tine in the thread and hopefully he can help you here. @Tine Andrejasic
With recent upgrades of the Venus/Cerbo firmware to 3.3X and REC-BMS 2Q Firmware 1.5 the REC 2Q BMS will now work properly on the Victron VE. CAN port instead of using the BMS.CAN port. This ...
Try resetting the CHRG and CANS parameters. Details are in the new manual on the rec-bms-na.com site
Here is some feedback from REC engineering that may address your challenge while giving you a level of system redundancy at the same time. Hope it helps I would go with 2 parallel systems.&n...
Here is something that may help. I havent had a chance to check it out myself yet. ## PLACEHOLDERS Use __BACKTICK__ to use placeholders that are listed below. You can type in a __BACKTICK...
Sure, you can query the Wifi module or use the RS485. The RS485 protocol is covered in the manual. I have a request in to enginerring for a list of http variables available and will post it ...
Check out this one. It may assist with many of your queries. And don't forget, these are all available in editable versions too. https://rec-bms-na.com/system-design-ideas/#48-50-wpfd-marin...
for most operations you connect to the Master to retreive all slave parameters, not to the slave. Only things like slave firmware updates . I see that your pack voltage is 104 volts so ...
are the green LEDs on the slave blinking about once a second? Are you using addresses 16 and 1 to try and connect?
Using the Wifi module and in the Tasks section you should be able to configure a different dropout voltage for each. You should have 1 available relay that will drive the Tyco directly and y...
Did you try changing the CANS parameter to 2 or 3?
Good clarification on this Ben. I think Trevor misunderstood your CANS (CAN speed) reference and thought you meant device address. Trevor, your CANS parameter should be set to either 2 or 3 depen...
Head office just advised us of an issue with 2.9.4 and we just posted a rerelease of the update here on the REC North America site https://rec-bms-na.com/product-manuals/#7-8-wpfd-rec-active-bms ...
Hi, congratulations on your new boat! To use the Victron smart shunt, you need to have the shunt wires connected across the shunt and treat it as a manual shunt. You can not rely on the CANB...
That e is the number of digits to offset the decimal, so the e-1 means your RAZL is 0.25 :) I think you mean you have a 2P16S system with 2 cells first paralleled than those 16 put in series to gi...
It looks like you have a pretty big cell imbalance problem. I see that your balancing ends at 3.58 but you stop charging at 3.53, which is part of the issue. If it were me I would adjust my ...
Thanks for sharing Jonny and a shoutout to Trond @Trond Røsvik The only time that should happen is if your USB is connected, as the WS500 thinks the ignition is turned on, which start...
On the more recent version of the precharge module there is a board mounted fuse that might be the problem. It will be black or grey and about 1.2cm (1/2")square and may have a glob of ...
Your settings should be retained and if the new FW version has new parameters they will be set to the standard default value. After an update the BMS will power cycle so make sure you have the wi-...
Hey Jonas, There is currently no bulk delete option and your solution was a great idea. I am including REC engineering in this reply so hopefully they can add it to the feature enhancement wish l...
ok, you will need to contact your dealer and request the slave version. We don't have it posted on our site yet. If we are your dealer, please just send us an email request to support@o...
Do your slaves have slave or standalone firmware? A slave will flash red/green then go out until the Master connects Did you set the slave addresses to be different?
you will likely need to clear the comms error before it will communicate, so connect one slave and try again
Thanks for Sharing Jonny, this is great feedback. Rick @Tine Andrejasic
I have discussed this with Tine and he is tweaking the FW to see if we can help smooth out the cycling of the dynamic loads. @Trond Røsvik are you interested in testing this update? Best, ...
Bill, Thats a whopper of a thruster. By my math, 950A x 24v = 23Kw / 746 = 30 HP!! Are you having issues now? If so, what is happening?
I havent come across this issue so I cant help right away. It may be you need to get around the bootloader to re-install it, but that is something only the folks at REC could do, or us with a...
It sounds like you may have blown some fuses in the REC BMS when you were moving things around. Also, how many beeps/LED flashes are you getting from the BMS? This will give us an error code...
I think you may be dealing with dynamically induced cycling caused when you get acceleration pulses every time the engine fires and is most notable at lower RPM. That's a wack of amps you are...
can you get a better pic, which shows the legend on the left so we know what the colors mean, and scaled to fill more of the screen. Also, what is your %SoC of your cells? Could it be that you ha...
Do you have any real time graphs that might help? Is your DVCC working (WS500 LED should be orange)?
