    It's never a good idea to connect batteries in parallel !

    You can do it via diodes . . . but with a resultant voltage drop.

    As far as i know all cellphone powerbanks and laptop batteries have multiple cells in parallel to obtain a high capacity and they work fine.

    As far as I'm aware they just have big cells in series, not in parallel . . .

    Laptop batteries have blocks of parallel cells put in series . Look on You Tube for E-bike battery repair....
