Are there advantages in using batteries in parallel over using batteries in series?

0

Yes. The main advantage in using batteries in parallel is, the capability of the batteries to do the work a single cell would prove incapable of doing. Connecting in parallel ensures the workload is shared amongst the cells connected to each other and not overstressing any cell in the circuit. An example using a 14500 900mAh Trustfire battery (The *** fire series battery has a C rating of 1.5): l This single cell is capable of doing (900mAh/1000)*(C or 1.5) or 1.45A worth of work; l The demand on the battery is 1.6A from an average 2.2 Ohm atomiser. As the battery can only produce 1.45A, the battery will be stressed when current is drawn from the load. l On the other hand, should we connect 2 or more cells in parallel; l (1.45)*2 or 3 = 2.9 or 4.35A We now have sufficient power available to adequately meet the work load of 1.6A, without stressing any of the batteries in the circuit.
