3. Sunpadow Li-Po Battery 2S 7.6V 6500mAh 140C Platin HV Shorty

Sunpadow’s HV (High Voltage) chemistry pushes boundaries, offering a 7.6V nominal output—0.2V higher than standard 2S packs.

This seemingly minor increase translates to a 5–7% RPM boost in 540-sized motors, a decisive edge in spec-class racing. The 140C discharge rate (910A peak) virtually eliminates voltage sag, even during sustained full-throttle straights.

The "shorty" form factor (97mm × 45mm × 34mm) caters to low-profile chassis like the Team Associated RC10B7, allowing strategic weight distribution.

Gold-plated 4mm bullet connectors reduce resistance by 18% compared to standard plugs, which is critical for maintaining efficiency in 130C+ setups.

However, HV compatibility is essential; only ESCs rated for 4.35V/cell (e.g., Hobbywing Xerun XD10 Pro) can unlock this pack’s full potential.

4. Team Corally Sport Racing 60C 4500mAh 6S 22.2V LiPo Battery

Engineered for 1/8-scale brutality, this 6S beast delivers 22.2V—enough to propel 2000kv motors beyond 50mph in off-road conditions.

The 60C rating (270A continuous) ensures consistent punch during backflips, though heat management becomes mandatory here. Internal nickel-plated copper braids between cells reduce impedance, while the dual-layer hard case dissipates thermal energy during prolonged use.

For speedrunners, pairing two packs in a series creates a 12S configuration capable of 100+ mph runs—if your ESC survives.

5. Gens Ace 4000mAh 2S 7.4V 60C HardCase Car Lipo Battery Pack

Gens Ace’s entry-level pack prioritizes durability over raw power. The 2.5mm-thick hard case withstands 30G impacts, a necessity for novice drivers learning throttle control.

The T-plug connector (also known as a Traxxas High-Current Connector) offers broad compatibility with budget ESCs like the Dynamite 2-in-1, though its 5A rating limits high-performance applications.

With a 60C discharge (240A burst), this battery comfortably handles 10th-scale stadium trucks but struggles in 4S monster setups. The 4000mAh capacity provides 12–15 minutes of runtime, while the 128mm × 43mm × 25mm dimensions suit most generic battery trays.

For under $50, it’s a pragmatic introduction to LiPo technology, though enthusiasts will eventually crave higher C ratings.

Here’s a brief guide on types of RC cars to help you understand the options you have.

LiPo Batteries: A Primer

What is a LiPo Battery?

A Lithium Polymer (LiPo) battery utilizes a polymer electrolyte in a flexible pouch cell format, distinguishing it from conventional lithium-ion batteries with rigid casings. The polymer electrolyte is typically a gel-like substance containing lithium salts suspended in a PVDF matrix.

LiPo cells deliver significantly higher energy density (150-200 Wh/kg) compared to NiMH (60-120 Wh/kg), enabling more compact and lightweight power solutions. Each cell maintains a nominal voltage of 3.7V versus the 1.2V of NiMH cells, allowing fewer cells in series for equivalent voltage requirements.

The chemistry eliminates memory effect issues present in older battery technologies while exhibiting comparatively low self-discharge rates (approximately 5% monthly versus 20-30% for NiMH).

This architecture supports higher discharge rates for power-intensive applications but requires strict charging protocols and thermal management to prevent catastrophic failure modes.

Choosing the Right LiPo Battery

Selecting the optimal LiPo battery isn’t just about raw power. It’s also about synergy with your RC car’s electronics and intended use. 

A mismatched pack can lead to thermal runaway, ESC failure, or subpar performance.

That said, here are things to look out for when shopping for a LiPo battery that suits your needs.

Compatibility Checklist

Before purchasing, verify:

• Dimensions: Must fit snugly in your battery tray (e.g., shorty packs for low-profile chassis like the Team Associated RC10B6.4).
• Connector Type: XT60 (general use), IC5 (high-current), Traxxas iD (proprietary), or Deans (low-resistance). Soldering skills may be required for swaps.
• ESC Voltage Handling: A 2S ESC will fry on 6S input. Check specs (e.g., Hobbywing Max8 supports up to 6S, while the Traxxas XL-5 is 2S/3S only).
• Weight Distribution: Heavy packs (e.g., 650g 6S batteries) improve traction in monster trucks, but lightweight builds benefit buggies and on-road cars.

Pro Tip: For speed runs, measure internal resistance (IR)—lower IR (≤2mΩ per cell) means less voltage sag under load.

Safety and Maintenance Tips for LiPo Batteries

LiPo batteries pack serious power—but with that comes serious responsibility. Mishandling can lead to performance loss or even fire risks, so a few smart habits will go a long way in keeping your gear (and workspace) safe.

Charging Best Practices

Always use a balance charger, like the SkyRC T200, to make sure each cell charges evenly. This reduces stress on the battery and extends its usable life.

Stick to 1C charging (e.g., charge a 5000mAh pack at 5A max) unless your battery specifically supports faster rates. It might be tempting to speed things up, but it usually shortens battery life.

Pro tip: Never charge a LiPo unattended. Place it in a LiPo-safe bag or a fireproof container like an ammo box, just in case.

If you don’t plan to use your battery for a few days, bring it to a storage charge level of 3.8V per cell. This reduces stress on the cells and prevents swelling or capacity loss.

Storage Guidelines

Store your LiPo packs in a cool, dry place, ideally between 15–25°C. Avoid leaving them in hot garages or freezing cold sheds, which can damage the cells over time.

Even when not in use, batteries self-discharge slowly. Check voltage every 2–3 months and top them up to storage charge if they dip too low. Dropping below 3.0V per cell can cause permanent damage.

Use fireproof containers or metal tins for long-term storage. It’s rare, but if a battery fails, you'll want that extra layer of protection.

Safety Essentials

Before every run, inspect your battery for any signs of swelling, leaks, or frayed wires. If anything looks off, don’t use it.

Most modern ESCs let you set a Low Voltage Cutoff (LVC) to avoid over-discharging. Set it around 3.2–3.4V per cell to stay in the safe zone.

When it’s finally time to retire a battery, fully discharge it (you can use a saltwater bath), then take it to a proper e-waste recycling center. Never throw it in the trash.

LiPo batteries demand respect and caution, as improper handling can result in fires or permanent damage. 

To avoid these from happening, follow these protocols rigorously.
