Best LiPo Batteries for ARRMA LIMITLESS 120 (1/7 8S RTR Street Speed)

Just picked up the ARRMA LIMITLESS 120 (1/7 8S RTR Street Speed)? Get ready to experience ground-hugging speed that feels more like flying than driving. This beast was made for straight-line acceleration—but breaking past the 100mph barrier all depends on the “fuel” you feed it: the right LiPo batteries.

Why do so many speed runners prefer CNHL soft packs over hardcase packs? It’s simple. Lower internal resistance and lighter weight translate directly into throttle response. That means less voltage drop when you pin the trigger and more consistent power delivery. In high-speed runs, those small differences can be the deciding factor between just making noise and setting a new personal record.

Worried about compatibility? Don’t be. CNHL packs come with EC5 connectors that plug right into ARRMA’s stock IC5 with a snug, solid feel. The only thing you lose is Spektrum’s Smart telemetry, but let’s be real—when you’re locked in at 120mph, the only thing that matters is steady, reliable power.

And if you’re chasing the upper limits—120mph and beyond—consider upgrading to QS8 connectors. Think of it like swapping a household water pipe for a fire hose: the larger contact surface means less resistance, lower heat, and more current delivered to the motor when it matters most. At extreme output, every drop of energy counts.
