QS8 Connector and 8AWG Wiring for High-Current 4S Builds
The defining feature of this Racing Series battery is its QS8 high-current connection paired with 8AWG power wires. This combination is particularly relevant to modified RC cars, speed-run platforms and other performance builds already designed around larger power connectors and heavier wiring.
Compared with the 5200mAh 4S 90C EC5 version, which uses 10AWG wires and weighs approximately 524g, this QS8 version uses thicker 8AWG wires and weighs approximately 544g. Both share the same nominal capacity, voltage and discharge ratings, but serve different connector and installation requirements.
A larger connector does not automatically increase vehicle speed or motor output. The complete electrical system, including the ESC, motor, wiring, connectors and battery, must be appropriately matched to the expected load.
Why Choose This Battery?
-
5200mAh capacity: A practical middle-capacity option balancing stored energy, physical size and weight.
-
90C continuous / 180C burst rating: Specified for demanding 4S brushless applications.
-
QS8 connector: Designed for high-current connection requirements in compatible performance builds.
-
8AWG power wires: Heavy-gauge wiring suited to the battery's high-current application focus.
-
76.96Wh nominal energy: Useful energy capacity without moving into substantially larger battery classes.
-
Softcase construction: Suitable for compatible installations with secure support, retention and protection.
-
Standard 4S LiPo chemistry: Uses conventional 16.8V maximum balance charging rather than LiHV charging.
4S LiPo Battery for RC Speed Runs and Custom Performance Cars
This 5200mAh 4S QS8 battery is particularly relevant to custom speed-run cars, GT-style builds and modified RC platforms with QS8-equipped power systems. Its 160mm-long pack format and approximately 544g weight should be considered when planning battery placement, chassis balance and secure retention.
For modified high-speed vehicles, confirm ESC voltage compatibility, connector suitability, battery clearance and the complete system load. Explore more options in the RC Speed Run Batteries Collection.
4S Power for Custom RC Boats and High-Current Systems
The QS8 connector and 8AWG wiring also make this pack an option for compatible 4S electric RC boats and custom high-current installations. Before use, verify the battery compartment, secure mounting, ESC requirements, connector type and operating load. For marine applications, keep the softcase protected from moisture, vibration and mechanical damage.
ARRMA QUAKE 4S DSC 4X4: Important Fitment Considerations
The ARRMA QUAKE 4S DSC 4X4 RTR supports 4S LiPo power, but this QS8 version is not a direct plug-and-play replacement for the stock IC5-equipped truck. Its 160mm length, softcase construction and different connector require careful evaluation before installation.
Only consider this pack where battery clearance, appropriate protection, secure retention and a properly engineered QS8 power connection have been confirmed. For more suitable choices, explore the ARRMA QUAKE 4S Batteries Collection.
QS8 Connector Compatibility: What You Need to Know
QS8 is a different physical connector standard from EC5, IC5 and XT90. It cannot be plugged directly into these connectors. A vehicle with a factory IC5 or EC5 connection requires an appropriately specified connector conversion or a different battery equipped with the matching plug.
For high-current applications, connector and adapter selection must account for current demand, polarity, wire gauge, connection quality and heat. Do not force incompatible connectors together or assume a small adapter is suitable for an extreme-current setup.
If your vehicle uses an IC5 connector, a conventional EC5-equipped CNHL battery can provide compatible main power when the rest of the battery specifications match. Standard CNHL batteries do not supply Spektrum Smart battery data.
Standard 4S LiPo Balance Charging
This is a standard 14.8V 4S LiPo battery, with a maximum charge voltage of 4.20V per cell, or 16.8V total. Use a compatible balance charger configured for standard 4S LiPo charging.
For routine charging, a balanced 1C rate is preferred. 5C is the stated maximum, not the everyday target. For this 5200mAh pack, 1C equals 5.2A. Use an appropriate charging lead and connect the balance plug correctly.
Do not charge this standard LiPo battery in a 4.35V-per-cell LiHV mode. Allow the pack to cool before charging and use a suitable storage program when it will not be used for an extended period.
Related Batteries and Alternatives
Need an EC5 connector instead? The CNHL Racing Series 5200mAh 4S 90C LiPo Battery with EC5 Plug offers the same nominal capacity, voltage and discharge rating with a different connector, 10AWG power wires and approximately 524g weight. Its EC5 main power connector is compatible with IC5 connections, although physical battery fitment and case requirements must still be checked.

FAQ
What RC models can use this 5200mAh 4S QS8 battery?
It is intended for compatible 4S RC speed-run cars, modified performance vehicles, custom RC boats and other QS8-equipped electrical systems. Check voltage, dimensions, weight, battery protection and power-system requirements before installation.
Is the QS8 connector compatible with EC5 or IC5?
No. QS8 does not directly mate with EC5 or IC5 connectors. A suitable connector conversion or a battery with the correct plug is required.
Can I use this battery in an ARRMA QUAKE 4S?
It is not a direct replacement for a stock QUAKE 4S. The truck uses IC5, while this battery has QS8. Its 160mm length and softcase construction also require careful fitment and protection checks. A correctly sized hardcase battery with an appropriate connector is generally a more straightforward stock-vehicle choice.
What is the difference between the QS8 and EC5 versions?
Both are rated at 5200mAh, 14.8V and 90C continuous discharge. The QS8 version has 8AWG wiring and weighs approximately 544g, while the EC5 version uses 10AWG wiring and weighs approximately 524g. Choose according to your connector system, installation requirements and current demand.
Is this battery hardcase or softcase?
It is a softcase LiPo battery. Use it only where the installation provides adequate mechanical support, secure retention and protection against impacts, abrasion and sharp components.
Does a 90C rating guarantee higher vehicle speed?
No. The 90C figure is the battery's stated continuous discharge rating, not the actual current drawn by the vehicle. Speed and performance also depend on the motor, ESC, gearing, drivetrain, load and operating conditions.
Can two 4S batteries be connected in series for an 8S system?
Yes, when the complete power system is designed for 8S operation and the packs are properly matched. Two identical 5200mAh 4S batteries connected in series provide 29.6V nominal (33.6V fully charged) while retaining 5200mAh capacity. Use batteries of the same model, age, condition and state of charge, with suitable wiring and connectors.
Can I charge this 4S battery in LiHV mode?
No. This is a standard LiPo battery. Select the 4S LiPo setting with a maximum balanced charge voltage of 16.8V, not the higher-voltage LiHV setting.
Should this battery always be charged at 5C?
No. For routine charging, a balanced 1C rate is preferred. 5C is the stated maximum, not the everyday target.
