CNHL Ultra-Thin Racing Series LiHV 4000mAh 7.6V 2S 120C Shorty Hard Case LiPo Battery with EC3 Plug

Product Specifications

What Makes This Shorty Pack Different

A 4000mAh 2S LiHV shorty hardcase is already a serious performance battery, but this one stands out for a more specific reason: it delivers that output in an unusually slim package. At only 18.5mm tall, it sits lower than many standard shorty packs and creates a clear advantage for chassis where battery height affects clearance, CG, or body fitment.

That matters because battery height often influences how a car feels on track. A lower pack can help a chassis feel flatter, more stable, and easier to place consistently through corners. On some builds, that is more meaningful than simply adding more capacity or a higher C number without considering pack shape.

The LiHV chemistry adds another advantage. Compared with a standard 7.4V pack, this battery charges to a higher voltage, which often gives a stronger early-run feel and more immediate throttle response. Combined with the 120C discharge rate, this makes it a serious performance pack for users who want a low-profile shorty that still feels strong under load.

Applications

This battery is best suited to 1/10 scale RC vehicles that use a 2S shorty hardcase layout and benefit from a lower battery profile. It makes the most sense in stadium trucks, drift cars, touring cars, and other low-CG builds where battery height and overall chassis balance play a big role in how the car drives.

Because it uses an EC3 plug, it is also relevant to users searching around EC3 battery and IC3 battery fitment on smaller surface RC platforms. As always, exact connector and tray fit should still be confirmed before purchase.

Why the Ultra-Thin 18.5mm Height Matters

The biggest difference with this pack is not just that it is shorty, LiHV, or 120C. It is that it keeps those specs in an unusually low-profile case. A battery at 18.5mm tall gives more flexibility on height-sensitive builds and can be especially attractive on platforms where even a few millimeters of extra battery thickness can change the setup.

That is why this battery can reasonably be understood as an ultra-thin shorty hardcase. It is built for users who care not just about electrical spec, but also about the physical shape of the battery and what that shape does to chassis behavior.

Compatible Platform References

This battery is especially relevant to 1/10 RC cars, stadium trucks, touring builds, drift cars, and custom low-CG projects that use a shorty hardcase layout. It is commonly considered for platforms from ARRMA, Losi, Team Associated, Axial, Tamiya, and HPI, provided the tray, voltage, and connector all match correctly.

It is also a strong match for scale lowriders such as the Redcat Caprice Classic RC Lowrider, where a compact shorty pack can provide dependable runtime while keeping the build practical and tidy.

An Upgrade Option for Tamiya Wild Willy 2 (WR-02)

For drivers who want longer runtime and a stronger punch from their Tamiya Wild Willy 2 (WR-02 chassis), this CNHL Racing Series LiHV 4000mAh 7.6V 2S 120C shorty pack can be a very interesting upgrade. The compact shorty case helps with fitment in tighter battery compartments compared with full-length hardcase packs, and the LiHV chemistry keeps the voltage more stable under load.

Because the original Wild Willy wiring uses a classic Tamiya-style connector, users may need an adapter or a connector upgrade to work with the EC3 plug on this pack. Many WR-02 owners choose to upgrade connectors at the same time for lower resistance and a cleaner high-performance setup.
