Coming back to this thread after 2 years. I kept using my old Tracker III since I last posted. Now, I’m going to get a Radiomaster Boxer. It comes with a battery holder for two 18650 Lithium Ion cells. There is a white 3-pin connector on this battery holder that plugs into the battery bay of the transmitter. I need to be able to plug this pack holder into my Electrifly Triton EQ battery charger, to charge the 18650 cells. I don’t know what the connector type is, that is on this battery holder. Does anyone know what it is called? I think this black connector is referred to as a “servo plug”.

I have been using a banana plug pair of wires with what looks to be a black Futaba type 3-pin connector on it (2 pins inside the 3-pin housing), that I would plug my Tracker III’s 8-cell AA NiMH pack into for charging. The Triton manual just referred to this charging lead as a banana plug to 2-pin connector. I don’t know if this 15 year old banana cable is compatible with the 18650 battery holder’s connector? And if it isn’t, I don’t know what the proper name is of the banana charging cable I need to charge the 18650 batteries.

I’ve attached some photos of the banana to “servo plug” charging wires that I currently have.
