Core Description
The CNHL Racing Series 5600mAh 3S2P 120C hardcase LiPo battery is designed for RC drivers who want a serious performance upgrade over basic 3S packs. The 5600mAh capacity gives useful runtime for bashing, racing, off-road driving, and speed-focused runs, while the 120C discharge rating supports aggressive throttle response and strong voltage behavior under load.
This is a performance-oriented 3S RC car battery, not a casual low-output pack. It is best suited to models that can properly use 11.1V power and benefit from stronger current delivery. In the right setup, the battery can help improve punch, corner-exit response, wheel speed, launch feel, and consistency during repeated throttle inputs.
The hardcase shell is especially important for surface RC use. It helps protect the cells from tray pressure, chassis vibration, impacts, battery straps, and repeated installation. For buggies, trucks, bashers, and performance 1/10 cars, a hardcase LiPo battery is often the safer and more durable direction than a soft pack when the tray supports it.
High-Performance 3S LiPo RC Battery for 1/10 RC Cars
The CNHL Racing Series 5600mAh 11.1V 3S2P 120C Hard Case LiPo Battery with EC5 Plug is suitable for selected 1/10 scale and 1/8 scale RC cars such as Slash, E-Maxx, Bandit, Rustler, Losi, Team Associated, and other racing buggies or trucks when voltage, dimensions, connector, and ESC rating match.
If you are ready to push your Kyosho Ultima 1/10 buggy harder, this battery is a powerful upgrade candidate. Its 3S2P layout, 120C discharge rating, hardcase construction, and EC5 plug make it a strong choice for drivers who want explosive punch, longer runtime, and a more responsive throttle feel from a performance RC setup.
As a high-output LiPo RC battery, it is built for users who demand both reliability and raw performance. It is well suited to off-road racing, bashing, high-traction runs, and speed-focused driving when the vehicle is properly set up for 3S power.
3S Full-Send Option for ARRMA Freedom Flyer 223S
The CNHL Racing Series 5600mAh 11.1V 3S 120C Hard Case LiPo Battery with EC5 Plug is an aggressive 3S power option for drivers who want to unlock the stronger side of the ARRMA Freedom Flyer 223S. On 3S, the Freedom Flyer 223S delivers harder acceleration, bigger wheelies, and the full brushless 223S personality.
Because the Freedom Flyer 223S uses a bottom-loaded battery tray, larger 3S hardcase packs require careful fit checking. The official tray limit is 140 × 50 × 35mm, while this battery measures approximately 139 × 47 × 37mm. That means length and width are close, but the height is above the listed tray limit, so this pack should be treated as a tight-fit / check-before-use option rather than a guaranteed drop-in fit.
The battery case, EC5 plug, and wires all compete for space under the battery door. For the cleanest setup, keep the connector near the chassis opening and route the wires upward instead of forcing everything inside the lower tray. Never force the battery door closed against the wires. A tight fit that crushes the leads, bends the plug, or stresses the latch is not a safe fit.

Why Choose a 5600mAh 3S 120C Hardcase Battery?
A 5600mAh 3S LiPo battery makes sense when you want more runtime than compact 4000mAh packs and more punch than basic 3S batteries, without moving into a much larger high-capacity format. It gives a useful balance of drive time, current support, and hardcase protection for performance RC car use.
The 120C discharge rating is the main performance advantage. In real driving, it can help the vehicle feel sharper during acceleration, high-load launches, repeated throttle changes, and aggressive off-road or street driving. Actual performance still depends on the ESC, motor, gearing, tires, surface grip, cooling, and vehicle condition.
The EC5 connector is another reason this pack fits higher-current 3S setups. EC5 is commonly used on larger RC cars, trucks, and power systems where smaller connectors may not be ideal. IC5 users may also search for similar battery options, but this battery is not a Spektrum Smart battery and does not provide Smart battery telemetry.
EC5 Plug and IC5 Search Compatibility Notes
This battery comes with an EC5 plug, a connector type commonly used in larger RC cars, trucks, boats, and high-current electric systems. EC5 and IC5 are often searched together because they appear in similar ARRMA, Spektrum, and larger RC power-system discussions.
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 5600mAh 3S 120C hardcase battery best used for?
It is best used in high-output 3S RC cars, buggies, trucks, bashers, and performance setups that need strong punch, hardcase protection, EC5 connector support, and practical 5600mAh runtime.
Can this battery work in the ARRMA Freedom Flyer 223S?
It can be considered as an aggressive 3S option only with careful fit checking. The battery measures about 139 × 47 × 37mm, while the listed Freedom Flyer 223S tray limit is 140 × 50 × 35mm, so height and wire routing must be confirmed before use.
Is this battery direct drop-in for the Freedom Flyer 223S?
No. Because the battery height is above the listed tray limit, it should not be promoted as a guaranteed drop-in fit. Do not force the battery door closed against the pack, plug, or wires.
Can this battery work in the Kyosho Ultima 1/10 buggy?
It can be considered for Kyosho Ultima 1/10 setups if the tray size, battery retention, EC5 connector setup, ESC rating, and 3S power system are suitable.
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 120C instead of a lower-C 3S battery?
A 120C battery can better support high-current demand during hard acceleration, high-load launches, repeated throttle changes, and aggressive driving. Actual results still depend on the ESC, motor, gearing, tires, cooling, and vehicle setup.
