Interesting there are also 6S1P out there.

Hello,

I'm jealous of you having such card, i'm looking for it since a long time and just discover this forum, I cannot send you message, maybe because i'm new user, so I will do it here in case you read it ;)

@inaglasshouse
For your project with e-208 module, how is it going? if you need any help to configure voltage/power map dont hesite to MP me. I can help to ensure you keep it all safe :)

Can't PM you either,

Open and good advice are always welcome if they enable us to use (or re-use) in all safety these modules. Do you have any recommendations, mainly voltage working range, current limits and derating when charging towards maximum voltge?

Thanks again,

Yep code can be found in this thread viewtopic.php?p=20335#p20335

I've rewritten this code for my project (using the Peugeot Battery), it needs a bit of tidying before I publish it here, but I hope to do this soon.
Hi VWJoe, I have a battery from an Opel Corsa-e arriving soon and I'm thinking of using it for a solar system. I saw this post and I would be very grateful if you could send me the code you have for this type of battery connection. You can write me PM :) .

Very nice tread, thank you for the info!

Does somebody have UN38.3 or any other datasheet for the CATL 6s2p module?

Datasheet for the cells here:


Interestingly the chemistry proportions are not listed but elsewhere I found 811 mentioned. Could somebody confirm?

THank you.
But this is for CALB cells, while the e208 use CATL cells/modules

Hi, question to those who have been using those modules. What happens when a module or two are disconnected from the BMS daisy chain? Can the data still be read and cells balanced? Each module has it's own BMS slave board, right?

Yes the BMS daisy chain will work with any number of modules. but the daisy chain wiring needs to be changed to close the chain.

Depends how you have them linked, the first is by the last module having a loopback hard-wired, in this case, if any module is disconnected all comms stop, the second is to have the slaves setup to a loopback (software), in this case, if you have 16 modules and say number 10 is disconnected the BMS would report 9 modules.
