About the CNHL Racing Series
The CNHL Racing Series focuses on delivering strong current output and consistent performance under load. In real driving, this translates to sharper throttle response, better mid-run consistency, and less voltage drop when pushing the vehicle harder.
Even on 2S setups, a higher-quality pack like this makes a noticeable difference compared to entry-level batteries.
A Smarter 2S Setup for the ARRMA INFRACTION 223S
Not every ARRMA INFRACTION 223S setup needs to jump straight into 3S power. A strong 2S pack like this actually makes the truck easier to understand and more enjoyable to drive in real-world conditions.
Instead of fighting for traction all the time, the chassis feels more balanced and predictable. You can focus on throttle control, smoother lines, and consistent runs rather than managing excessive power.
This 6600mAh 2S hardcase pack works especially well here because it adds runtime without losing responsiveness. It’s a very practical starting point before stepping into 3S setups.

Applications
This battery is best suited for performance-oriented 2S setups where control, runtime, and durability are all important factors.
- 1/10 and 1/8 RC cars
- Street bashers and on-road platforms
- Stadium trucks and 2WD builds
- Drivers who prefer controlled power over aggressive setups
FAQ
Is a 2S battery still powerful enough?
Yes. With a high discharge rating like 120C, this battery still delivers strong acceleration, just in a more controllable way than 3S setups.
Why choose a 6600mAh 2S battery?
It provides longer runtime compared to smaller packs while maintaining stable voltage under load.
Is hardcase important?
For RC cars, yes. A hardcase helps protect the battery from impacts and chassis movement during driving.
Notice
- Battery compatibility depends on voltage, connector, and available space.
- Stop charging when each cell reaches 4.2V.
- Check battery condition before first use.
- Perform several balance cycles if performance is not optimal initially.
