This adapter is used to connect two EC5 batteries in series to double the voltage, e.g., two 3S 11.1V batteries connected via this adapter to a 6S 22.2V speed control. Connecting batteries in series only doubles the voltage, this does NOT double the C rating.
Note: Do NOT use this adapter during charging!
Wire AWG: 14
Wire Length: Wire length of each leg of the circuit is ~90mm.
