XT90 and EC5 are pretty close to the same thing. I have always used XT150 connectors, but am going to change to QS8 ends for my Infraction V2 with an XLX2 and TP 4050
Both my chargers and my discharger have XT60 connectors. None of my packs have the XT60 connector. I use adapters to charge.Also at the the moment I only have a Spektrum S2100 charger. So I guess I would have to make an IC3 adapter no matter what connectors I choose. Smh. I would hate to have to buy a new charger. Do you guys have any recommendations for a charger just in case?
