Cells are marketed with capacities anywhere from 2100 all the way in which up to 3400mAh. You’d begin by welding 10 parallel teams of four cells every, then you definately’d connect those 10 parallel groups in sequence to make one rectangular battery. Any battery that claims to have a capacity over 3500mAh right now you should be suspect of, as a result of they’re very uncommon.
