Quick Fit Check
The CNHL Ultra-Thin Racing Series LiHV 6000mAh 15.2V 4S 120C Hard Case LiPo Battery with EC5 Plug is a high-performance 4S hardcase battery built for users who want strong LiHV voltage, high current capability, and a more tray-friendly profile than many full-size 4S packs. Its biggest advantage is simple: at just 37mm tall, this is an unusually thin 4S hardcase battery for its capacity class.
Before ordering, check four things first: your vehicle should support 4S LiHV voltage, the battery tray should fit this pack’s dimensions, the setup should match an EC5 connector, and the chassis should suit a battery weighing about 479g. If those points line up, this battery is a very strong option for users who want a 6000mAh 4S pack without stepping into the thicker hardcase formats that can cause fitment problems.

What Makes This 6000mAh 4S LiHV Hardcase Different
A 6000mAh 4S hardcase LiHV battery is already a serious performance battery, but this one stands out for a more specific reason: it keeps that capacity and LiHV voltage in a notably slimmer hardcase format. With a pack height of only 37mm, it sits much closer to the thickness many users associate with 3S hardcase batteries than with typical 4S 6000mAh packs.
That matters because battery height is often the fitment problem that decides whether a pack works cleanly or not. Many users can find room for a 4S pack in length and width, but run into trouble once the battery becomes too tall for the tray, straps, or body shell. This pack solves that problem more elegantly than most 4S hardcase batteries in its class.
The LiHV chemistry adds another advantage. Compared with a standard 14.8V pack, this battery charges to a higher voltage, which often gives a stronger early-run feel, sharper throttle response, and a more energetic overall character. Combined with the 120C discharge rate, it becomes a very strong choice for users who want a slim hardcase battery that still feels serious under load.
Applications
This battery is best suited to 4S RC cars, trucks, truggies, and other hardcase-ready platforms that need strong output but may be more sensitive to battery height than to overall length. It is especially attractive for users who want a high-capacity 4S pack with strong punch and LiHV voltage, but without the thick hardcase shape that many large 4S batteries use.
Because it uses an EC5 connector, it is also relevant to users searching around EC5 battery and IC5 battery fitment, especially on larger surface RC platforms where this connector class is common.
Why the Ultra-Thin 37mm Height Matters
The most important feature of this battery is not just that it is 4S, LiHV, or 6000mAh. It is that it delivers those specs in an unusually low-profile hardcase. For many RC users, that changes the buying decision completely. A thick pack may look good on paper, but if it creates tray clearance problems or pushes body fitment too far, it becomes less practical in real use.
A hardcase battery at 37mm tall is much easier to work with on height-sensitive platforms. That is why this pack can be understood as a kind of ultra-thin 4S hardcase rather than just another 6000mAh option.
A Practical LiHV 4S Option for Traxxas Jato 4X4 VXL
For drivers looking for a bit more punch and extended runtime from their Traxxas Jato 4X4 VXL, a LiHV 4S setup is worth considering. Compared with standard 14.8V packs, LiHV batteries charge to a slightly higher voltage, which usually translates into a stronger initial throttle feel on the track or during bashing sessions.
What makes this battery especially interesting for the Jato is not just the capacity, but also the low-profile hardcase format. On fast off-road platforms, a thinner hardcase can make fitment easier and keep the battery setup cleaner than a thicker full-size 4S pack.

A Strong Fit for Traxxas Ford Raptor R 4X4 Ultimate
This 6000mAh 15.2V 4S LiHV hardcase is also a strong match for Traxxas short course trucks such as the Ford Raptor R 4X4 Ultimate. With its 120C discharge rate, it delivers both the burst power for big launches and the steady throttle response many drivers want from a higher-end 4S pack.

FAQ
What makes this battery different from a normal 4S 6000mAh hardcase?
Its biggest difference is the low-profile hardcase. At only 37mm tall, it is much thinner than many full-size 4S hardcase batteries, which makes it especially useful on height-sensitive trays.
What is the benefit of LiHV batteries?
LiHV batteries charge to a slightly higher voltage than standard LiPo batteries, which often improves early-run throttle response and overall punch.
Why is the 37mm height important?
Because battery height is often the real fitment limit on hardcase-ready RC platforms. A thinner pack can fit more cleanly under straps, trays, and body shells than a thicker alternative.
Is EC5 relevant for IC5 users?
Many buyers search EC5 and IC5 battery setups together because they are commonly associated with the same class of larger RC power systems. Users should still confirm their exact connector setup before purchase.
