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 ...

Dear Adam, 64x 280Ah LFP? to replace 40x 200Ah gel?    Should be less LFP no?  I was told by a batterie supplier that 14x 24V 280 Ah LFP would do.. The fourth alternator is removed as in it\'...

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...

It could be a couple of things.   First, check the charge parameter of the alternator.  It may have a very conservative profile.  The Wakespeed site has quite a few preconfigured profile...

I\'ve installed a WS500 about 6 months ago and it\'s working fine at first sight. When giving more attention to the data, I noticed that the alternator only goes to about 27V and never reaches the ...

Adam makes a good point about capacity, and you would need some very large wires off of those alternators, very good belt drives, and will need to be careful about side loading on the crank bearing...

You have nearly 29 kW of maximum power generation and a just over 12 kWh of LFP. That is not well matched, particularly if you are trying to charge at 0.5C, or 6 kW. Also, 14 cells in a 2S2P lay...

Dear Rick, I am planning to install wakespeed 500\'s on a yacht with twin engines. One engine with 2x 400 amps 24V alternators, the other just one 400 Amps 24V alternator All three charge ...

I think I figured it out. I\'m bench testing everything in my garage with the inverter plugged into a 15A 120v circuit. I\'ve limited the MP3k to 13A input. From what I read last night after more s...

Not sure what\'s causing  your issue -- I have a similar hardware setup  with a MP3K and am able to charge at the full 120A capacity reliably. However, I am using lower voltages for  bulk and float...

Interesting start to my Multiplus 3K with the ABMS. Followed the instructions on page 20 of the ABMS/Victron/Wakespeed manual to get the BMS talking and managing the MP3K via CANBus. I did updat...

I\'m running the same basic configuration  you are (16 eve 280 cells), and have the same  question about voltage settings for these cells. I reduced the max cell voltage for now to reduce wear on t...

I just got the Active BMS working. My battery pack is 16 EVE 280Ah cells connected in a 4P4S configuration. Chemistry: I the Chemistry settings list is relatively short. Is Winston the best e...

This was originally a reply to another post. Relay DCH is meant to be connected to all Victron loads and charge devices. (Non Victron loads can be added here in a single contactor configuration)...

It looks like the BMS is pulling back before your BMS starts to balance. You can try to enable balancing at a slightly lower value. We are putting together a bit of an instructional video on ...
