In the world of remote-controlled (RC) models—whether you're an RC car enthusiast, Go Kart racer, or drone pilot—battery plug compatibility is an unavoidable topic. With different brands like Traxxas and HobbyKing using varied connector types, Remote Control Car Battery Adapters have become essential for safe and efficient connectivity.
As a global leader in RC products, HobbyKing offers a comprehensive range of high-quality RC battery connectors and adapters. From go kart battery plug adapters to RC battery plugs XT60 to XT30, HobbyKing has it all. This guide will help you understand adapter types, buying tips, and our top recommendations.
1. What Is an RC Battery Adapter, and Why Do You Need One?
An RC battery adapter is an intermediate accessory used to connect different types of batteries with electronic devices like ESCs (Electronic Speed Controllers), chargers, motors, etc. It converts the battery connector from one type to another. Since RC models use a wide variety of batteries and connectors (such as XT60, EC3, Deans T-Plug, JST, etc.), a battery adapter is crucial for compatibility and flexibility.
Core functions:
- Improves Compatibility: Seamlessly connect batteries and control systems from different brands.
- Simplifies Setup: No cutting or soldering required—just plug and play.
- Protects Your Connectors: Reduces wear and tear from frequent plug switching.
2. Common Battery Connector Types and Adapter Conversions
- XT60: Stable output, suitable for medium to large RC cars. e.g., XT60 to XT30, XT60 to EC5, XT60 to TRX
- XT30: Ideal for small current devices like micro drones. e.g., XT30 to XT60, XT30 to JST
- Deans (T-Plug): High discharge, extremely durable. e.g., T-Plug to XT60, T-Plug to EC3
- EC3/EC5: Popular in high-power systems. e.g., EC5 to XT60, EC3 to T-Plug
- JST: Best for small receivers or LED lights. e.g., JST to BEC, JST-XH balance adapter
- TRX (Traxxas Plug): Exclusive to Traxxas RC models. e.g., TRX to XT60, TRX to Deans
- HXT 4mm/5.5mm: Large current, often used in airplanes. e.g., HXT to XT90, HXT to T-Plug
- MPX: Common in older aircraft models. e.g., MPX to XT60, MPX to T-Plug
3. Benefits of Using RC Battery Adapters
- Boosted Compatibility: One battery can serve multiple devices, reducing cost.
- Quick Swap: No need for soldering—just plug and go.
- Brand Versatility: Supports major RC brands like HobbyKing, Traxxas, Arrma, Losi.
- Safe Design: Premium copper wires, heat-resistant insulation, and stable high-current performance.
4. Key Considerations When Buying RC Battery Adapters
- Check Connector Direction: For example, XT60 “Male” to XT30 “Female.” Wrong orientation won’t work.
- Current Carrying Capacity: Match the wire gauge to your battery’s discharge rate (14AWG or thicker recommended).
- Material & Solder Quality: Go for pure copper and high-temp silicone insulation.
- Brand Compatibility: Some adapters are brand-specific (e.g., Traxxas plugs), but HobbyKing adapters work flawlessly with all their batteries, ESCs, and motors.
- Adapter Type Clarity: Distinguish between charging adapters and battery output adapters.
5. Top-Selling Battery Adapters at HobbyKing
- XT60 Male to XT30 Female Adapter
This conversion cable is used for compatible connection between XT plugs of different specifications, and is commonly used in drones, FPV, RC models and other scenarios.Convert XT60 Male devices (such as batteries, chargers) to XT30 Female to adapt to low current devices.
1.For example:
- Large battery (XT60) → Small aircraft/image transmission (XT30)
- Charger (XT60 output) → Small capacity battery (XT30 input)
2.Current limit:
- XT60 rated current: 60A continuous (short-term peak is higher).
- XT30 rated current: 30A continuous.
The adapter cable must be used according to the XT30 standard (i.e. long-term current ≤30A).
1.For example:
Large battery (XT60) → small aircraft/image transmission (XT30)
Charger (XT60 output) → small capacity battery (XT30 input)
2.UAV/FPV field:
Large capacity 6S battery (XT60) powers small flying aircraft (XT30).
Charger (XT60 output port) charges small capacity 2S~3S battery (XT30).
RC model:
High current power supply (such as PDB distribution board) connects low power consumption devices (such as LED lights, receivers).
1.For example:
Large battery (XT60) → Small aircraft/image transmission (XT30)
Charger (XT60 output) → Small capacity battery (XT30 input)
2. Typical application scenarios
UAV/FPV field:
Large capacity 6S battery (XT60) powers small flying drone (XT30).
3. Precautions for purchase and use
(1) Wire quality
16AWG silicone wire (high temperature resistance and good flexibility) is recommended. Poor quality wire may cause overheating or voltage drop.
The welding point should be firm to avoid cold welding (easy to melt under high current).
(2) Current limit
Continuous current ≤30A (XT30 upper limit), instantaneous peak value can be slightly higher (such as 35A).
If the device demand exceeds 30A, it is recommended to directly use the XT60 interface or replace the battery.
(3) Polarity check
The positive and negative poles of XT60 and XT30 must correspond (red wire is positive and black wire is negative).
Use a multimeter to confirm that there is no short circuit before use.
(4) Alternative solution
If frequent conversion is required, you can purchase a parallel splitter board for XT60 to XT30 (supports multiple devices).
- T-Connector to XT60 Battery Adapter Lead
Connects T-plug batteries to XT60 ESCs or chargers.
- XT60 Male to EC5 Female
Go Kart racers’ favorite—designed for high-power setups.
- XT60 Female to HXT 3.5mm Adapter (2pcs)

- XT90 Male to T Plug Female
This conversion cable is used to connect devices with XT90 interface (high current device) and T plug (T Plug/Deans Ultra) interface, and is commonly used in RC model cars, boats, high-power drones and other scenarios.
Purpose: Convert XT90 Male devices (such as high-current batteries, chargers) to T
Plug Female to adapt to old or specific models of RC devices.
Typical scenarios:High-current LiPo battery (XT90) → old RC car/boat (T plug)
Charger (XT90 output) → old battery (T plug input)
RC model car/boat:New high-current battery (XT90) powers old ESC/motor (T plug).
Compatible with old charger (T plug) to charge XT90 battery (need to confirm polarity).
DIY high-power equipment:Situations such as electric skateboards, large robots, etc. that require different interface adaptation.
