Developer of electronic prototypes i am, quisera participate in the project which to design a bank of batteries, I can propose Lifepo4 battery type? They are more stable and more number of charges that lition, have also developed projects. I have to clarify several points, which capacity you need for the battery? for serial and parallel connection we are speaking. PS: to develop a system bootstrap fabricare with load balancer to optimize the batteries, we recommend the 18650 format.
