DIYBMS for Lithium titanate battery cells (LTO)

Just checking if the LTO board has gone further, or if there is still a problem?

Hi Stuart. Very interesting project. I note it is dating from Dec '20. Can you advise me on where the project is now?

Probably a good place to start is with my YouTube videos.

Heres the playlist…

Hi,

Is this design available at Github/diyBMSv4 for v4.4 ?

Rgds

I still see it…

Disc shaped design of PCB not in Github. Isn’t it ?

ahh… sorry… I didn’t see it was a reply about the disc shaped one.
@stuart would have to answer. He can probably send you the files??

Hi Stuart, love what you have done with this BMS. If we need to order these same BMS’s how much would they cost in what lots. Also need to discuss about them further so let me know how and where to connect. Sorry for being so abrupt, have been looking for these exact same BMS’s for a while and am new to this community.

Love what you have done with this Bank. I am new to this field and need some help and guidance creating the exact same bank that you have. Any help would be greatly appreciated. Also have you documented this build anywhere found you from Facebook even left a reply there for you.

Hope this will help

Thank you for the reply…… is there anyone or any place i can order a readymade board. Complete with programming. Also do you have a complete list of items used for your project like the display and software like you have made.

I basically want to replicate the system as in the video seems perfect.

This is great
