What battery does the Losi Asphalt Late Model GROM use?
The Losi Asphalt Late Model GROM uses a 2S LiPo battery and a compact tray layout that is best suited to smaller hard-to-miss, easy-to-fit battery packs. In practical terms, the safest buying approach is to start with the actual fit limits first, then think about runtime and upgrade goals second. For this platform, battery size and connector planning matter just as much as voltage.
| Item | Specification |
|---|---|
| Battery Type | 2S LiPo |
| Battery Tray Size | Approx. 102 x 34mm |
| Stock Connector | IC2 |
| Factory Power System | 2S brushed setup |
| Best Use Case | Driveway racing, parking lot laps, short-track style on-road driving |
What battery size works best?
For the Asphalt Late Model GROM, the best battery is not automatically the biggest one that can be forced into the tray. A good pack for this car should fit cleanly, sit low, and avoid upsetting the balance of a small AWD on-road chassis. In most cases, compact 2S packs in the smaller-capacity range make more sense than oversized packs that add weight and complicate fitment.
That is especially true for a platform like this one. The car is meant to be fun in smaller paved spaces, where repeatable handling matters more than brute-force top speed. A battery that keeps the chassis composed through quick direction changes often feels better than a heavier pack chosen only for extra runtime.
Replacement battery vs runtime upgrade vs brushless plan
Most buyers fall into one of three groups. The first group just wants a simple replacement for the stock 2S pack. The second wants a little more runtime for casual laps with family or friends. The third group is already thinking ahead to a brushless conversion, higher gearing, or a more serious tuning direction.
If you are in the first group, the smartest option is usually a compact 2S battery that fits the tray with minimal hassle. If you are in the second, you can look slightly higher in capacity, but only if the shape still matches the available space. If you are in the third group, discharge strength and overall pack quality start to matter more, because once the car is pushed beyond its brushed stock setup, battery choice becomes part of the performance equation rather than just an accessory decision.
Important note about the IC2 connector
The stock Losi Asphalt Late Model GROM uses an IC2 connector. That matters because many aftermarket batteries are not designed as a direct plug-in match for IC2-equipped vehicles. In real-world use, alternative battery setups are usually handled with an adapter solution rather than by assuming direct connector compatibility.
For this reason, anyone shopping outside the original battery format should check both physical fit and connector strategy before buying. In many cases, that means using an adapter for an IC2-equipped vehicle to run a battery with a different plug style, such as EC3 or JST, depending on the battery format selected.
Why this car does not need a giant battery to be fun
One mistake people make with small on-road cars is treating them like mini bashers or mini speed-run builds from day one. That is not really what makes the Asphalt Late Model GROM interesting. This car is built around short-track style driving, tidy corner entry, and close racing in spaces where a larger 1/10 setup may feel excessive.
That is why battery choice should match the platform’s purpose. A sensible 2S setup is often the best place to start. If the goal later becomes brushless conversion or aggressive gearing, that is a separate step. But for stock use, controlled power and proper balance usually create a better driving experience than simply adding more battery than the chassis really needs.
What makes the Asphalt Late Model GROM different from the NASCAR version?
Part of the interest around this release comes from how naturally it invites comparison with the Losi NASCAR platform. The clipless body system is one of the most obvious upgrades in day-to-day use, because it makes battery access and maintenance less annoying. The late model body shape also gives the car a more planted, purpose-built look for short-track style driving.
That matters for battery buyers because this car is not being treated by the community as just a decorative shelf piece. A lot of early attention has focused on how well it could work as a genuinely fun paved-surface racing platform, and that means buyers are more likely to think about replacement packs, extra run time, and future power upgrades.
Practical battery buying checklist
| Question | Why It Matters |
|---|---|
| Does it fit within 102 x 34mm? | Fit comes first. A pack that does not sit properly is not worth forcing into the car. |
| Is it a 2S LiPo? | That is the stock voltage format for this platform. |
| What connector does the battery use? | The vehicle uses IC2, so many aftermarket packs will require an adapter plan. |
| Is the goal stock driving or future brushless use? | A stock replacement and a future upgrade battery are not always the same decision. |
| Is extra runtime worth extra weight? | Sometimes yes, but on a small on-road chassis, added weight can change the feel of the car. |
Who should buy extra batteries for this platform?
This collection makes the most sense for three types of owners. First, casual users who want a second pack so the car does not sit still after one run. Second, families or club-style drivers who want longer sessions on a driveway, cul-de-sac, or parking lot circuit. Third, hobbyists who already know they are likely to experiment with gearing, electronics, or brushless conversion later.
In all three cases, the battery choice should stay grounded in the platform’s real size and use case. That sounds obvious, but it is exactly where many small-scale RC battery purchases go wrong.
