I'm new at 6v receiver packs and would like to know what type of connectors to use between the perfect switch and a 2s LiPo pack. I'm asking because the pack wires are considerably heavier gauge wire than the perfect switch wire. My power systems, watts up and charger are setup for 4mm connectors. Therefore the most convenient would be to use 4mm bullets between the pack and switch/regulator. Is there a better way?
