Hi @Goran_Trajilovic ,
Thanks for your proposal, I’m interested.
I’m currently in the process of trying to build my first 48v LTO battery bank with 21 cells*40ah (that’s about 2kwh).
I would like to buy your remaining round shape BMS and controller.
Are you okay to ship to France ?
Please reply soon
Thanks a lot 
Regards,
Ned
Hi @stuart ,
I just discovered your nice project about this round shape micro BMS for LTO cells, and I’m very interested to build my own battery bank with 21 of these modules.
Have you done any upgrade to the ‘round’ design since your last post in this thread (more than a year ago) ?
I have seen on GitHub that the genuine ‘single module’ design is versioned 4.50, but this round shape is 4.21.
Can I go without worries with the ‘old’ version, or do you recommend to make use of the latest 4.50 ? In this case , would you mind posting the upgraded files here, or via PM ?
Thank you so much for your help
Best regards
Ned , from France
