You are using some wacky numbers. A 30 amp-hour battery seems heroic, and a USB connection is only rated for 2 amps, so my conclusion is that you either don't know enough to do this, or else you are awfully sloppy in writing about it. For instance, you don't specify whether you are talking about charging or output conditions.
i am talking about both input and output conditions. what should i use to charge my batteries? i bought a TP4056 charging chip to charge my old laptop batteries. I want to make my own power bank using old laptop batteries connected in parallel.
