lithium 18650 series first or parallel? Answered
Looking at doing a lithium battery build but trying to cut down on soldering or spot welding.
My idea is to use a stack of 3 18650 batteries in series pushed inside a piece of PVC pipe, thus making a 12V tube and then having multiples joined together to make the final battery
Is there any reason why people mostly use a set of batteries is paralel then series?
