The "2p" is misleading. It depends one the cells thatyou are using, and how capable these cells are. For example, if you are using 3000mah cells rated at 15C, it may be worthwhile to use a 2P configuration. Any cell size smaller than 3000mah or a cell that can't handle 45amps continuous should be used in a parallel configuration for our purposes. If you use a larger cell, then it is your choice if you want to parallel the cells up.
