recently found 9V 6800Mah Li-ion Rechargeable Micro USB Batteries,seems to be easy option for all connections/charging.
Any tips? or you agree that it be good?
I think of getting a dozen = 10= 90V 68 000Mah
And please,share mid-drive motor options ...

sorted byYou can have either 90V with 6,800mAh or 9V with 68,000mAh but not both.
Depends if they're wires in series or parallel.
Also is it Mah or mAh?
Big difference between milli and Mega.
EDIT:
Generally portable USB power banks are a good guide as to the best you can expect of a battery pack of the same capacity in terms of price, weight and size.
The same 61Wh (9V * 6.8Ah) capacity in a power bank (~16,500mAh@3.7V) would run you about £15-20. So anyone offering such a 9V, 6.8Ah pack for those prices would be very attractive.
Anything below that you should be highly suspicious, and something that's £3 each and a fraction of the size can't be anything other than a scam. (edited)
