So, some background. I currently run my car on 3s with several batteries that I switched a few years back to all use EC5 Connectors (upgraded from deans and adapters). My son's car runs on 2s (or nimh) and all his batteries run EC3 connectors (what came with the truck and batteries.). Well, I'm looking at possibly running some 4S in the (nearish) future but don't want to invest in new batteries right now. I know I can run 2 2s batteries in series to equal 4s, however I'm not sure how the amperage stacks up throughout the system when using multiples. I know the EC3 aren't recommended for 4S, but would I be ok running 2 2s using a series adapter with the current connectors (2 EC3 in series to one EC5 output to the ESC,) or should I go through and change all the 2S (and my son's car) to EC5?
