Why Battery Choice Still Matters for the RC10 1989 Stealth Car
Unlike many modern RC kits, the RC10 Masami Edition stays true to its roots—it’s up to the builder to complete the drivetrain. That includes selecting a compatible 2S LiPo battery that won’t just fit, but also deliver balanced performance without overpowering the system.
What to Look For in a Battery
The RC10’s classic tub chassis has space constraints. You’ll want to choose a battery that’s under ~140mm in length, has a hard case for safety and rigidity, and provides stable discharge. The original spec suggests a 7.2V NiMH, but today’s builders are better served with a lightweight, modern 7.4V 2S LiPo setup.
Top Pick: CNHL Racing Series 6600mAh 7.4V 2S 120C
So, what makes this 6600mAh pack a solid match? It’s got the runtime, low internal resistance, and enough punch to keep things fun—without going overboard on a vintage setup. The hard case adds that rugged feel, and the size is just right for the RC10’s tub chassis—no weird fitment issues, no bulky corners.

Other 2S Hard Case Options Available
Depending on your ESC placement and wiring plan, you may also consider lower-profile packs (like 5000mAh or shorty formats). All CNHL hard case LiPos in this collection are selected to be vintage chassis friendly while delivering consistent punch.
More Than Just Power—Part of the Build
Masami’s 1989 win wasn’t just about speed. It was about control, setup, and smooth delivery. The battery you choose today plays a similar role. It shapes your driving feel, CG balance, and overall experience.

Frequently Asked Questions
What battery does the RC10 1989 Stealth Car require?
Stick with a 2S 7.4V LiPo. The manual might mention the old 7.2V NiMH packs, but come on—it's 2025. A 2S LiPo gives you better power, runtime, and reliability. Just make sure it’s a hard case. Safety matters, especially with a vintage-style chassis.
Will modern 2S LiPo batteries fit the chassis?
Yes, most standard-size or shorty 2S hard case packs will fit just fine in the RC10’s tub chassis. The CNHL 6600mAh 2S we recommend fits perfectly. If you’ve modded your top plate or are running a huge motor, double-check dimensions—but for most builds, you’re good to go.
Is this car just for display, or can it be raced?
It’s definitely race-worthy. A lot of collectors keep it pristine, but under the hood it’s a fully functional 2WD buggy. Builders around the world are running it in vintage classes. Just install the right electronics, and it’ll rip.
Why choose the CNHL 6600mAh pack specifically?
It hits the sweet spot—enough juice, high discharge, and built tough. It doesn’t overpower vintage ESCs, and it holds up great whether you're doing laps or showing it off. It just works, without drama.
Is this really Masami’s replica car?
Yep. Masami Hirosaka worked directly with Team Associated on this re-release. Everything from the flame paint job to the KO Propo chassis sticker has been recreated. It’s as close to the 1989 World Champion buggy as you’ll ever get in kit form.
