Choosing among RC batteries & chargers comes down to more than voltage: you need the right battery format, capacity, and intended vehicle fit without paying for specifications that do not match your setup. The 2X Ovonic 7.4V 100C 2S 5000mAh Shorty LiPo is aimed at 1/10 RC cars, but its shorty dimensions make fit the key decision.
Quick verdict
The 2X Ovonic pack is a sensible choice for an RC hobbyist who wants two 2S LiPo batteries for a listed 1/10 car, buggy, racer, or drifting application. The combination of 7.4V, 5000mAh capacity, and a 100C discharge rating gives you a clearly defined specification set, while the $38 price applies to the two-battery package. The catch is equally clear: the 95×46×25 mm shape needs to suit the battery space in your vehicle.
Ovonic 2S 5000mAh Shorty LiPo Battery (2-Pack)

The strongest reason to choose this pack is the combination of two batteries and a 5000mAh capacity per battery, which makes it relevant to drivers who want a spare in the same purchase. The limitation is the shorty format: at 95×46×25 mm per battery, it is a specific physical shape rather than a generic replacement size. The title also targets 1/10 RC cars, buggies, racers, and related applications, keeping its intended use focused.
Who it suits
This battery makes the most sense for someone running a 1/10 RC vehicle designed around a 2S, 7.4V LiPo setup. It is also a practical match for shoppers who prefer a two-pack instead of buying a single battery at a time. The 5000mAh capacity is the headline figure to consider when comparing the pack with the needs of your vehicle and driving routine.
It is less compelling if your priority is a different battery shape or voltage. The shorty designation and stated dimensions are not minor details; they are central to whether this battery belongs on your shortlist.
What stands out from the listed details
The specification profile is easy to understand: lithium-polymer chemistry, 2S configuration, 7.4V voltage, 5000mAh capacity, and a 100C discharge rating. The 100C figure should be treated as a specification rather than a guarantee of speed, handling, or runtime. Likewise, the 7.4V and 2S figures identify the electrical format without proving that every 1/10 RC car will accept it.
The application wording names 1/10 Formula models, professional drifting cars, off-road cars, and examples such as TLR 22 and Losi 22-series vehicles. That gives the battery a more focused use case than a charger-and-battery bundle intended for several chemistries.
Meaningful trade-offs
At USD 38.00, the appeal is tied to receiving two batteries in the package, not to an unspecified performance claim. You should also account for the 211g-per-battery weight and the compact dimensions when considering how the battery will sit in your vehicle. Because the connector details are not presented consistently across the available specifications, they should not be treated as a deciding advantage here.
Bottom line
Choose the 2X Ovonic 7.4V 100C 2S 5000mAh Shorty LiPo when you want a two-battery pack for a listed 1/10 RC application and the 95×46×25 mm shorty format suits your vehicle. Pass on it when that shape does not fit your setup; the battery's most important trade-off is physical format, not the headline 100C number.
