Alright time to bug you guys again. Why do some Li-FE batteries have 2 connectors (Receiver Connector and a balance connector), and others have 3 (Receiver Connecter, balance connector, and an EC3 Connector). I’m asking because I want to charge these (Spektrum) batteries with my spektrum charger. When I charge my Li-Po batteries I have to have my ec3 and balance plug in. Do I need to do this with a LI-Fe battery or can I just plug in the balance connector.
