Double your runtime without touching a soldering iron using this heavy-duty Spektrum Parallel Y-Harness. This adapter is designed to connect two batteries to a single Electronic Speed Controller (ESC) to double your capacity (mAh) while keeping the voltage (S-count) the same.
For example, if you connect two 3S 5000mAh batteries using this harness, your ESC will see a single 3S 10,000mAh battery. This is perfect for drivers who want longer bashing sessions or extended trail runs without stopping to swap packs.
Equipped with Spektrum's Smart IC5 connectors, this harness supports the data transfer required for Smart Technology (when used with Smart electronics) but remains fully backward compatible with standard EC5 connectors.
Key Features
-
Parallel Configuration: Wires two batteries in parallel to double the available amperage and capacity (Runtime) while maintaining the same voltage.
-
Heavy-Duty Wire: Constructed with thick 10 AWG silicone wire to handle high-current draw without overheating or creating resistance bottlenecks.
-
Smart Technology: The IC5 connectors feature the "data pin" that allows Smart Batteries to communicate individual cell data to a Smart ESC, even when run in parallel.
-
IC5 / EC5 Compatibility: While designed for IC5, these connectors are physically compatible with older, standard EC5 plugs, making this a versatile adapter for almost any large-scale setup.
-
Flexible Length: The 6-inch cable length allows for flexible battery placement in the tray without putting strain on the ESC wires.

Critical Usage Warning
Do not confuse this with a Series Adapter!
-
Parallel (This Product): Doubles Runtime (mAh). Voltage stays the SAME.
-
Series: Doubles Voltage (Speed). Capacity stays the SAME.
-
Note: Always use two identical batteries (same brand, age, capacity, and C-rating) when running in parallel to ensure they discharge evenly.
Tech Tip: When running in parallel, your runtime doubles, which means your motor runs for twice as long without a cool-down break.
Keep an eye on your motor temperatures! Extended runs can overheat a motor even if the gearing is correct for a single pack.
