few question about diybms

[onlineapps-cloud]

hi, sorry if i opened issue in wrong repo, i have few question about your bms, for my it's not clear if your bms support some of features.

I will use 18650 li-ion battery
question is if your BMS can work in this mode:

1. Each cell can be connected separately to BMS?.
2. I can connect like 100-120 cells to BMS?.
3. BMS can commutate automatically battery in series and parallel? to achieve 36V or 48V ?.
4. BMS can extract power for each cell separately for maximum efficiency?.
5. Where i can buy your BMS and modules? your website not working.
   

Remark:
i don't want to solder battery in series or parallel, because i want some times to replace battery, so i will connect all battery using battery holders to BMS.
I want to use used battery with different capacity, because of this i want to connect battery separately, for maximum efficiency.
