Hello all!
I hope some smart people will be able to help me. I have been in the renewables business for some time and have some knowledge on batteries and such. Now I would like to build a 'portable' power station with a solar input, but I need help with the wiring of my batteries.
Originally I sourced a Pylontech H2 (96V 37AH) which I had deconstructed and consists of 4 blocks of 7cells each of 37M pouch cells (3.2V 37Ah). Every block, like on the picture is 24V and wired in a 7S configuration.
I would like to build a power pack of 24V, with all 4 blocks so I think that would be 7S4P then.
My biggest question are the balance leads. Every pack had a balance lead tot a central board which I can no longer use. I bought a 7-14S BMS but I don't get how to wire it. Do I only wire it to the first battery block and will the rest be balanced automatically or do I have to go to every block, but I only have one BMS.
I think that I will use the existing connector and cable and splice in my BMS, but do I have to daisy chain them to block 2 and 3 and 4 or only balance 1.
I am scratching my head with this one, would really love for people to help me out!
