About the CNHL Racing Series
The CNHL Racing Series is built for drivers who care about immediate throttle response, strong mid-run consistency, and the confidence that comes from using a real hardcase pack in a demanding chassis. This is not a soft, easygoing battery line. It is aimed at vehicles that benefit from higher discharge performance and stronger electrical stability under load.
In practical use, that means harder launches, cleaner acceleration, and less of that flat feeling some lower-output packs develop once the run gets serious.
A Strong 3S Match for the ARRMA INFRACTION 223S
If you want the ARRMA INFRACTION 223S to feel like more than just a quick on-road basher, a battery like this is the kind of upgrade that changes the character of the truck in the right way. On 2S, the platform is already fun. On 3S, it starts to feel sharper, more serious, and much closer to the street-bashing attitude that made the Infraction name so popular.
This pack suits that platform particularly well because the hardcase construction makes sense for a street-focused chassis, while the 6600mAh capacity gives enough runtime to enjoy the extra power without turning the setup into a one-run novelty. It is a good middle ground for drivers who want stronger performance but still care about usable session length.

Applications
This 3S hardcase pack is most at home in performance-focused ground vehicles where battery protection, punch, and runtime all matter. That includes street bashers, stadium trucks, performance 2WD and 4WD builds, and RC platforms that benefit from the extra confidence of a hard shell pack.
- Street bashers and on-road speed-focused builds
- RC stadium trucks
- 1/10 and 1/8 scale hardcase-friendly platforms
- High-power ARRMA, Losi, Team Associated, and Axial setups
- Drivers who want longer runtime without giving up strong 3S punch
As always, fit depends on the combination of voltage, connector, and tray dimensions, not just the model name alone.

FAQ
Is 6600mAh too much for a 3S street basher?
Not necessarily. For many drivers, 6600mAh is a very practical size because it gives longer runtime without forcing you into an overly heavy setup. The real fit question is whether your tray and handling preferences support it.
Why choose a hardcase battery?
A hardcase battery adds physical protection, which is especially useful in RC cars and trucks where impacts, chassis flex, and battery movement are part of normal use.
Is EC5 suitable for performance builds?
Yes. EC5 connectors are widely used in higher-current RC setups and are commonly associated with IC5-style ecosystems in modern performance vehicles.
Notice
- Battery compatibility depends on matching voltage, connector, and available tray space.
- Please stop charging when the cell voltage reaches 4.2V per cell.
- Inspect battery condition and voltage before first use.
- If the pack does not reach full performance initially, perform several balance charge cycles.
