Which BMS are you using with dbus-serialbattery?

[mr-manuel]

To get a little overview which BMS are used by the community with this driver we ask you to participate to this poll :-)

Since polls are a little restricted in discussions and the options are limited we are doing it this way.

Please upvote for the BMS you are using with this driver

This can simply be done by pressing the arrow up under your BMS name.

Testing

Since we do not have all BMS for testing, we need as many people per BMS to test pre-release drivers. If you are available to test changes/improvements for your driver, please write a reply under the BMS that you have with "available to test".

ANT

[dmorgado18]

I'm using it on a JBD cable and everything goes well.
I wanted to add an Ant Bms via bluetooth, but I can't.
I have an emus BMS with PC cable to configure it on the computer and additionally it has a G1 Smartphone Connectivity Module. Possible to work with your script

Daly

[towatai]

2 parallel Daly Smart BMS 150A, 8s connected via RS485. The UART-Connection seems much slower and i had sporadic, short disconnects (The holy "error #67"). Since i use the RS485-Cables, everthing seems to work fine.
Each battery pack has a Heltec Active Balancer, which can be switched on and off via a Shelly 1 (via NodeRed) depending on the battery voltage. So the thing does not run all the time.

[ofernander]

@mr-manuel using a single 4S 200A Daly BMS on your latest Beta release and after some custom config it's working great! Really appreciate all the input you've given to this project.

[RoDeP0]

Daly Sinowealth on a 200 Ah custom build. Worked flawlessly last year on VenusOS 2.8, yet have to get it working on 3.2x (RPI 3B+). Documentation says "Disabled by default as it is causing issues". What are those issues?

[Louisvdw]

@RoDeP0 the Sinowealth comunications protocol is very basic and as such if we enable the driver for it most other BMS also respond on those commands and are incorrectly picked up as being a Sinowealth BMS. The rest of the calls thein fail.
So if you are using a Sinowealth and want to upgrade to the latest version you will need to enable the Sinowealth driver and disable all the others. And then it should work like before.

3x 300A on one install and 1x 300A on diferent install

JBD/LLT

[packrat1969]

What is the model number for this JBD BMS with active balancing?

[wherzig]

My JBD BMS (JBD = JiaBaiDa with active Balancer 160mA SP22S003B) is not working with Version 1.0 and higher. It is only recognized with Version 0.14.3 . Very strange.

[sledge2019]

Using the 1.0 Version together with a JBD-AP20S006-L20S-200A-B and a NEEY active Balancer on an 18S battery. Runs like a charme.

[pmarches]

Using v1.0.20230531 with two centerpower LifePo4, 12V, 200Ah.

JKBMS

[MatKra89]

3 Jkbms B2A20S20P @ 16S 280Ah LFP, Raspberrypi 3B and connected via the pi's internal BLUETOOTH!
Works well, but some problems with SoC reset. A newer version (nightly build) is able to reset all of the JK´s, but the last stable (v1.2.20240408) is not. The nightly build has problems with the correct CVL for me, it always goes up to the limit of the bms, i.e. way too high. The sporadic transmission errors with individual cell voltages being too high/low are also gone in the nightly build, that's fine and I'm looking forward to a new version.
Big praise from the YouTube channel Energie&Hobby at this point.

BD6A20S10P

[noonscoomo]

2 x JK BMS @ 16S 230Ah LFP on Cerbo GX via RS485.
Had trouble to learn first to set the cell voltages in settings.py before trying to set a guess for "charge" since at LFP the charge value always resets to 100% because of the default low max voltage setting.

[Pim57]

BD6A20S15P Bluetooth to Cerbo GX,SOC reset works great

[Baxter117]

• 3x JK over BLE in System1 ( 3x 16S )

• 2x JK over BLE in System2 ( 2x 18S )

• 1x JK over BLE in System3 (1x 16S )

hope BLE connection will be improved in future :)

Renogy

[mark-1003]

Using two Renogy Batteries/BMS's.
Each one connected with an Rs485 interface.

[BlueY21]

Hello mark-1003,
I also have Renogy Smart Batteries connected in parallel and am in the process of connecting them to a Cerbo GX. I understand that presently, they each need to be connected separately :-(
I have Okiwan RJ45-USB Serial Adapters but I think the signal pin positions on their RJ45 male connectors do not match the signal pin positions on the Renogy battery RJ45 sockets. (The Okiwan Adapters and all the similar products are intended to connect PCs to data communications equipment console ports,) I'm planning on making a cat6-type adapter cable to transpose the Tx, Rx, and Gnd signals and omit the extraneous rs232 control signals provided by the Okiwan adapter.
How did you connect your batteries to your Venus device?
What type of RJ45-USB Serial Adapters did you use?
What signals and connector pins on the batteries did you use?
Is it required to use the UpLink socket on the Renogy batteries, vs. the DnLink socket?
I currently use the Renogy BT-2 Bluetooth Dongle. Can that still be used if the Batteries are connected to the Cerbo?
I plan on putting the dbus-serial battery .tar file and a config.ini file on a micro-sd chip and put then leave it pluged into the Cerbo. Is that what you did?
For the 100Ah batteries, I plan to set the MAX_BATTERY_CHARGE_CURRENT to 20 (=0.2C) and the MAX_BATTERY_DISCHARGE_CURRENT to 100 in the config.ini. Would this be correct?
Have you considered any of the Battery Aggregator additional drivers?

Your advice would be greatly appreciated.

[gambleben]

I'm using the Renogy USB RS485 to USB adapter and the Renogy BT-2 Bluetooth Dongle concurrently. I did the original development on the Renogy driver but haven't contributed anything in quite awhile. At one time I had a working fork that aggregated all four of my Renogy batteries to make them look like one massive battery to dbus-serialbattery, but I haven't kept the code up to date and need to re-implement that for the latest version of VenusOS and this driver, ideally in a more elegant fashion along with refactoring to use modbus and pull in all of the alarms now that we have full documentation of the protocol.
One thing to note is that when you plug in the Renogy bluetooth, it assigns new MODBUS addresses to all of the connected batteries. New from the factory I think they default to 254 or something like that, but after connecting the BT-2 module they will start at address 50 and count up from there.

[jaa2261]

I have a bank of 8 Renogy RBT100LFP12S batteries. Happy to help with testing.
@gambleben how do you get the RS485 and BT-2 to operate concurrently? Do you use the Renogy Hub or a RS485 splitter?

TIAN/LIFE Power

[Justice12t]

I think most of the work for the 12v battery has been gathered.

[Justice12t]

Available to test

[LilDucky]

I have a Tian Power 48V BMS that is 15 cell and badged as OptimumNano. This driver almost works, and I had to reduce the number of temp sensors to get rid of an out of range error. The driver could really use a refactor to correctly implement the group number byte and the following length byte.

Another improvement would be to implement the daisy chained module addressing to save on ports for connection.

Edited to add: found a python lib that may make this work a ton easier.

https://github.com/Frankkkkk/python-pylontech

I will try but my python skills are horrendous.
