I need an electronic circuit design for a lithium battery charge

Budget 117$ per month

Description
I'm currently developing an air purifier and need a circuit design that utilises 6no. 18650 lithium ion batteries as the internal power source to run a 12volt electric fan. The batteries are to be connected as 3 pairs in parallel, then connected in series to give an 11.1 volts output. The batteries will be permanently housed inside the unit and will be recharged via a 'jack' plug.
I don't want to reinvent the wheel and want to use ready made circuits (usually from China) to build my unit.
Many thanks,
Gary
