As promised I will describe circuit and Plan of my bidirectinal converter.
I suggest you guys will ask and discuss about it, so i will transfer this building description to a separate thread in electrical section, You all Know his section is for concepts, not for discussions.
Since i had put the first ideas of this issues already in a thread there, i will continue there with the converters building details :

I might add, belonging to this section, that the first build is still working in my mobile home, now during one year.
1st Build:
Size: 10s18p (three bicycle packs in parallel)
Electrics battery: 36 V 52 Ah nominal (limited to 4.0 v/cell it is about 46 Ah) Since it is used cells, it might be a bit less
Electrics converter: max 12 Amps Up direction. max 10 Amps low direction. Load voltage 12.8 V, Boost voltage 13.2 V (and higher)
Cycles: The systems has supplied close to 20 kWh to the car, so might be the aequivalent 10+ full cycles.
The second build i did for a friend of mine, which builds a small Mobile home based on a 24 V Car system:
2nd Build
Size: 10s12p (currently two bicycle packs in parallel, possible upgrade to double))
Electrics battery: 36 V 24 Ah nominal (Llmited to 4.0 v/cell it is about 22Ah) Since it is used cells, it might be a bit less
Electrics converter: max 5 Amps Up direction. Max 7 Amps low direction. Load voltage 25,6 V, Boost voltage 26.2 V (and higher)
Cycles: The build is just ready and will start operation next year.
