You will want to contact Wakespeed tech support for these specs.

I\'ve come across information here and there that suggests the WS500 can use REC provided current via CAN.  However, the WS500 documentation says \"Note: If instability is seen with Current Regulat...

Regarding the Van Wiring harness and wakespeed alternator temperature sense: 1. What is the stator/field connector type/model? 2. What is the alternator temperature sense connector type/model? ...

Jamie, which parameter asks for Parallel strings? Anyway, connecting your cells in 4P4S would result essentially in 1 Parallel string with 1120Ah capacity at 12V In my experience i treat the ...

REC is continually adding new CANBus inverter support. They are also committed to extending that support, so if you have a CANBus enabled inverter and can get a hold of the PGN and protocol for int...

Good questions. The WS500  ignition and feature-in wires can use any 8.5-48v source, as long as your overall system has a common ground for both 12 and 24v battery systems(which it should). T...

I have a Volvo Penta D2-75 12v engine driving a 24v Prestolite alternator.  I have a couple of questions.  Can the WS500 be fed 12v to power it and the regulate 24v or do I need to make up a r...

Hi Jan. I was thinking that on the R terminal there seems to be an insulator which means that it is only picking up the heat transmitted through the stud which has a lot of surface area for heat...

Quote from Jamieson Ide on February 8, 2022, 12:30 pm My question was why did you use the R terminal for the heat sensor?  I guess it works but wonder why you didn\'t use a case bolt like one wher...

Quote from Ben on August 19, 2021, 10:06 am Nice Jan, You got it working. One comment on your last picture. The cable connected to P looks very thin. I can be wrong, because the picture. ...

Hi Jan, hope you are still monitoring this and thank you so much. I have exactly the same alternator and have my shiny new WS500 to connect to it. I found the brush connections a fiddle, had ...

I dont think you want to set it back to half power mode on an OV disconnect.  My solution in the past was to just add the interposing relay in parallel with your your OV coil and cut your field as ...

its on the todo list but it could be a while

Wow...more participants, thanks ! I\'ll take 14 24V MG batteries with built in BMS. They are 100% compatible with the Victron system which is already in place.  The previous AGM capacity was fin...

Thank you Rick. Much appreciated.

The idea of 14-16 self-contained 12V LFP batteries, without any kind of monitoring of their state, is too scary for me. What happens if one of them decides to shutdown?

Kees, If it were me, I would be working it the other way around.  Lay out a spreadsheet and list all of your loads, current draws, and run hours per day.   Add in what overcapacity you might wan...

Thank you. I understand parallel vs. series . I\'m asking about the specific settings in the \"Battery Pack Data\" section of the software where it asks for Chemistry, Capacity, Cycle and Parallel ...

Back of my napkin math says you currently have 48 kWh hour of useable battery capacity in your gel cells. So if you are going to have the equivalent, or maybe more \'cause it\'s always better, you ...

Dear Adam and Rick, thank you for your quick response. In fact the yacht has already Victron 12V Gel batteries of 200Ah each 40 pieces in total.  There are 4x alternators of 400 amps each, one w...

Ideally the wakespeed is controlled by the BMS through CANbus, but in case of a critical shutoff of the battery I want to kill the alternator at the same time. I read all the guides, and as far as ...

Will there be support for firmware 2.4.3 any time soon?

If you have 4 parallel \"banks\" of 4 cells in series, you\'re capacity is 1120Ah. Parallelling banks adds capacity, while serializing banks increases voltage. Since you have 4s, you\'re in a 12V s...

Hi Rick, we measured the voltage drop and it\'s about 0.4V, wire size is 90mm2 or AWG 3/0. The wakespeed gets voltage information from the battery through a volt sensing wire.

There is no master reset but you can use the SOCS command to set your SOC to an approximate value and over the next several full cycles it will zero in on the correct value.  Remember that many of ...

Thank you. This is very helpful I\'ll reference the EVE datasheet and plug in numbers. Can you clarify the question on Capacity & Parallel Strings? With a 4P4S configuration of 280ah cells,...

Thanks, please do.  What would be ideal is a REC Active BMS that supported 8s.  The Active BMS is a nice unit and seems well suited for the needs of vans, RVs and boats with a mix of charging sourc...

I think that REC may have a solution for that later this year.  I will post something when I get more details.

Jan, I suggest you contact tech support at Wakespeed on this one. http://www.wakespeed.com/contact.html Something seems strange here as the WS500 slowly ramps up over a minimum of 15 seconds,...

The default chemistries are just meant as a starting point.  You will need to find the manufacturers specs for your model of battery and apply those numbers.  You may even want to start on the cons...

Thanks for the reply.  But again this just addresses charge control, but not discharge control.  Is there a way to control my Victron BatteryProtect to disable DC loads if the battery gets too low?...

if your field is at 100% it seems it may be a limitation of your alternator.  at a 100% field output your WS500 is doing everything it can.  Strange, but I have found that most any 12V alternator w...

When my Victron chargers are running (Quattro 100A and Skylla 100A) and I start the alternator with the wakespeed WS500, we\'ve experienced an overvoltage scenario. The battery bank shut down to pr...

The Q Series actually includes an Opto relay for interlocking manually with a non CAN charging device.  On a rise in cell voltage the BMS first toggles the opto relay, then if the voltage continues...

Hi Rick, I\'m using the CPE#8 LiFePO4 profile, so target voltage is about 28.8V. I had the alternator in small mode, but changed it to 100% output through the software and redid the test. Field ...

Hello, I\'m looking at the Rec Q BMS for my existing 24V system in my van.  The title of this thread just mentions REC but it is in the REC Q subforum so I hope this is the right place. I have a...

Quick Question: Is there a way of resetting the BMS when connecting to a new battery pack? It seems when I connect the BMS to a new battery the SOC and other attributes seem to carryover from t...
