Quick Fit Check
The CNHL Racing Series 5200mAh 11.1V 3S 90C LiPo Battery with EC5 Plug is a high-output 3S pack for RC users who want more punch than a basic 3S battery while still keeping a practical 5200mAh runtime range. With 11.1V 3S voltage, 5200mAh capacity, 90C continuous discharge output, 10AWG wire, and an EC5 plug, this battery is suitable for selected RC cars, trucks, boats, crawlers, and dual 3S power systems where size, voltage, and connector match.
This battery is a strong choice when your model supports 11.1V 3S LiPo power, has enough tray space for a 160 × 45 × 28mm pack, can safely handle an approximately 395g battery, and uses an EC5 connector or a properly rated adapter. EC5 and IC5 are often searched together in larger RC power systems, but this battery does not provide Spektrum Smart battery data.

Core Description
The CNHL Racing Series 5200mAh 3S 90C LiPo battery is designed for RC drivers and boat users who need stronger discharge output than a basic 3S pack. The 5200mAh capacity gives practical runtime for bashing, boating, crawling, and general performance use, while the 90C discharge rating helps support sharper throttle response and stronger voltage behavior under load.
Compared with lower-C 3S batteries, this pack is better suited to setups that pull harder during acceleration, launch, corner exit, boat runs, or repeated throttle changes. It is still compact enough for many 1/10 and selected larger RC platforms, but the 160mm length means tray fitment should always be checked carefully before purchase.
The EC5 plug and 10AWG wiring make this pack relevant for higher-current 3S systems. EC5 is commonly used on larger RC cars, boats, trucks, and power systems where smaller connector formats may not be ideal. IC5 users may also search for similar battery setups, but this battery is not a Spektrum Smart battery and does not provide Smart battery telemetry.
Traxxas Spartan and Spartan SR Battery Note
If you are choosing batteries for the Traxxas Spartan or Traxxas Spartan SR, the most common full-performance setup is two matching 3S LiPo batteries. Two 3S packs run together as a 6S system, giving the boat the voltage needed for strong acceleration and high-speed Deep-V performance. A pair of 5200mAh 3S packs becomes a 6S 5200mAh setup; voltage doubles, but capacity stays the same.
This CNHL Racing Series 5200mAh 3S 90C EC5 pack is a strong option for Spartan owners who want a balance of runtime, punch, and high-current connector support. Since the stock Spartan and Spartan SR use Traxxas-style battery connectors, this EC5 pack requires a suitable EC5 to TRX adapter or a proper ESC-side connector change. For boat use, always use two identical packs with the same capacity, connector, age, charge level, and condition.
Check tray fitment, wire routing, water-cooling clearance, battery straps, and connector position before running at full throttle. For more compatible options, visit the Traxxas Spartan & Spartan SR battery upgrade collection.
Compatible RC Car, Truck, and Crawler Applications
The CNHL Racing Series 5200mAh 11.1V 3S 90C LiPo Battery with EC5 Plug can also be used in selected RC cars, trucks, crawlers, and high-power ground platforms that support 3S LiPo voltage and have enough tray space. It is relevant for users looking for a stronger 3S pack for acceleration, bashing, crawling wheel speed, and general performance driving.
In the Traxxas lineup, this pack may be considered for 3S-compatible vehicles such as the E-Maxx, Bandit, Rustler VXL, and other models where voltage, tray size, connector, and current demand are suitable. Because Traxxas connector setups vary by model and generation, always confirm whether an EC5 battery works directly or whether a properly rated adapter or connector conversion is needed.
For Traxxas TRX-4 crawler enthusiasts, this battery may be useful when 3S power and higher output are desired, but tray length, battery height, wire exit, and driving style should be checked first. You can find more crawler-focused choices in the Traxxas TRX4 LiPo Battery Collection.
Why Choose a 5200mAh 3S 90C EC5 Battery?
A 5200mAh 3S LiPo battery is a practical upgrade size because it gives more runtime than smaller 3000mAh–4000mAh packs without moving into an overly large format for many RC cars and boats. It is especially useful for drivers and boaters who want a longer session while keeping a responsive throttle feel.
The 90C discharge rating makes this pack more performance-focused than many everyday 3S batteries. It is a good fit when the model needs strong current support under acceleration, heavy prop load, aggressive driving, or repeated throttle changes.
The EC5 connector is also an important part of the setup. For RC boats and larger vehicles, EC5 can be a cleaner high-current direction than smaller connector types, provided your ESC connector, polarity, and current requirements match.
EC5 Plug and IC5 Search Compatibility Notes
This battery comes with an EC5 plug, a connector type commonly used in larger RC boats, trucks, and high-current electric systems. EC5 and IC5 are often searched together because they appear in similar power-system discussions and model recommendations.
This battery is not a Spektrum Smart battery and does not provide Smart battery data. If your model uses an IC5-equipped ESC, confirm physical connector fit, polarity, current rating, wire clearance, and charger setup before use.

FAQ
What is this 5200mAh 3S 90C LiPo battery best used for?
It is best used in 3S-compatible RC cars, trucks, boats, crawlers, and dual 3S setups that need strong discharge output, practical runtime, and EC5 connector support.
Can this battery work in the Traxxas Spartan or Spartan SR?
Yes, it can be used as part of a matched dual 3S setup for the Traxxas Spartan and Spartan SR. Use two identical packs to create a 6S 5200mAh setup, and confirm tray fitment, connector setup, and secure mounting before running.
Do I need one or two batteries for Traxxas Spartan full-performance running?
For the common full-performance Spartan setup, use two matching 3S LiPo batteries. Two 3S packs connected together create a 6S system; the voltage doubles, but the capacity remains 5200mAh.
Is this battery suitable for Traxxas TRX-4?
It may be used in selected TRX-4 setups if the vehicle supports 3S power and the battery tray can fit a 160mm long pack. For crawling, check weight, tray clearance, and connector setup carefully before use.
Is EC5 the same as IC5?
No. EC5 and IC5 are often searched together because they appear in similar larger RC power systems, but this battery has an EC5 plug and does not include Spektrum Smart battery data.
Why choose 90C instead of a lower-C 3S battery?
A higher discharge rating can help support stronger current demand during acceleration, boat launches, heavy load, or repeated throttle changes. Actual performance still depends on the model, ESC, motor, prop, gearing, and wiring.
Notice
- Only use a compatible LiPo balance charger designed for 3S LiPo batteries.
- Stop charging immediately if any cell exceeds 4.2V.
