Here is a really easy battery system to build.
No busbars or flimsy ballance leads.
I hope that this video can bring some light in how to connect this type of battery module to a Daly bms, ore any other bms.

The leads in the battery module is very thin and if you short them or load them with a to high current those can fail, leaving you with a useless cell module!
The small fuses to the balance leads are rated to 750mA but I recommend you to use a bms that use 200mA or less to balance the cells.

Note:
Those batterys are dangerous and should be handled with respect and not be installed in your house. A stand alone garage or shed is what i recommend.
Cell chemistry: NCM 712
