A Traxxas Slash 4×4 needs a three-cell LiPo pack, the correct connector, and a charger matched to both chemistry and charging rate. The real challenge is compatibility: XT60 power, Traxxas-style connectors, and 12V ride-on chargers serve very different vehicles. Several parts here also support drivetrain and suspension upgrades rather than charging.

More Details On Our Top Picks
Of the seven choices, this is the only direct battery match for a 1/10 Slash 4×4. A three-cell LiPo pack supplies the nominal 11.1V that Slash electronics expect, while the XT60 connector carries substantial current for acceleration and steep terrain.
The two-pack format suits frequent runners who dislike pausing between sessions. You still need a LiPo balance charger because this listing identifies the batteries and adapters, not a complete charging system.
Positive Points
- Two 5,200mAh packs reduce charger downtime between runs.
- The 75C continuous rating suits power-hungry RC applications.
- XT60 output offers a secure connection for high-current setups.
- Adapters expand connector compatibility across supported models.
Practical Considerations
- Connector adapters must match the charger lead and Slash battery connection.
- LiPo storage calls for the voltage management required by your charger.
Key Attributes
Built With In Mind
You benefit most as a Slash 4×4 hobbyist using a 3S LiPo setup and already owning suitable charging equipment.
Another Choice May Suit
The Integy XHD Steel Rear Universal Driveshafts suit hobbyists strengthening the Slash drivetrain rather than replacing its battery.
Slide past battery shopping and this pair addresses a different Slash ownership concern: rear drivetrain strength. Universal joints connect the rear driveshafts while allowing the sliding movement needed as suspension geometry changes over uneven surfaces.
Steel construction is the central attraction for hobbyists running rough tracks or dealing with repeated high-load launches. It is not a charger or battery, so it belongs beside the PowerHobby pack only in a broader Slash maintenance plan.
The Upside
- A two-piece set covers both rear shaft positions.
- Sliding universal joints accommodate suspension travel.
- Steel construction adds strength for demanding terrain.
- The set supports 1/10 Slash and Stampede 4X4 platforms.
Trade-Offs To Consider
- Installation requires removing the stock rear drivetrain components.
- Owners commonly inspect universal joints for binding after rough runs.
- Fitment does not imply power-system or charger compatibility.
Feature Snapshot
Workshop Pick
You’ll appreciate this pair most as an experienced Slash 4×4 hobbyist planning a rear drivetrain upgrade.
Consider Something Else When
The PowerHobby 3S 11.1V battery is the relevant choice for Slash hobbyists who need replacement power rather than stronger rear shafts.
The Stage 1 kit shifts attention from electrical upkeep to appearance and suspension hardware. Machined aluminum components give the Slash 4×4 LCG a more deliberate, purpose-built look, particularly under workshop lighting or at an RC exhibition.
The kit is limited to the LCG platform, so you should verify your chassis before ordering. Compared with the Integy driveshafts, it changes the visible suspension structure instead of strengthening the rear axle connection.
What Helps Most
- Aluminum alloy components create a distinctive finish.
- Multiple anodized colors support personalizing the chassis.
- Machined hardware complements a detailed LCG build.
Points To Note
- The kit serves the 1/10 Slash 4×4 LCG only.
- Installation can require careful alignment of several suspension parts.
- Appearance remains the primary attraction for many hobbyists.
- None of the listed pieces charges or stores battery energy.
Made For
You’ll find this kit most useful as an LCG owner focused on cosmetic customization and a coordinated aluminum finish.
Look Elsewhere When
Choose the Integy XHD Steel rear driveshafts instead when rear drivetrain reinforcement matters more than appearance.
Crocodile clips make this maintainer practical for stationary 12V sealed lead-acid batteries. That fits a ride-on vehicle or utility vehicle laid up between outings, where accessible terminals matter more than an RC-style battery plug.
Do not connect it to the 11.1V PowerHobby LiPo pack. Chemistry and connector compatibility must both match, and this charger is built around 12V lead-acid applications rather than three-cell LiPo charging.
The Helpful Details
- Crocodile clips connect directly to accessible battery terminals.
- Automatic operation suits routine storage charging.
- The 12V format targets common sealed lead-acid packs.
Factors To Consider
- It is incompatible with the Slash’s three-cell LiPo system.
- Confirm the battery is 12V sealed lead-acid before connection.
- Loose leads require tidy storage to prevent cable damage.
Quick Facts
Right Fit For
You’ll find this maintainer suitable for owners of 12V sealed lead-acid ride-on or utility batteries.
Reach For A Different Pick
The PowerHobby 3S battery is the proper fit for Slash 4×4 hobbyists operating a LiPo-powered RC platform.
A selectable charging current gives this maintainer more flexibility than the compact ToiCottage 12V unit. You can use it across 12V and 24V lead-acid applications, with compatibility extending to AGM, gel, flooded, EFB, calcium, maintenance-free, and deep-cycle batteries.
Despite the broad lead-acid feature set, it remains outside the Slash 4×4 LiPo charging category. The pure-copper coils and aluminum housing may aid heat handling, yet connector and chemistry compatibility are the decisive ownership details.
Well-Handled Touches
- Selectable output supports multiple 12V and 24V batteries.
- Adjustable current accommodates different battery sizes.
- Broad lead-acid chemistry support serves mixed fleets.
- Copper coils and aluminum housing support heat management.
- Automatic maintenance suits vehicles stored between outings.
Potential Drawbacks
- The charger does not support Slash-compatible LiPo charging.
- Terminal connection and battery chemistry must be verified carefully.
Technical Reference
Who It Suits Best
You benefit most when maintaining several 12V or 24V lead-acid vehicle batteries with different current requirements.
Not Your Match When
The ToiCottage crocodile-clip maintainer suits a simpler setup centered on one compatible 12V sealed lead-acid battery.
This charger focuses on battery-powered children’s ride-on vehicles with a 12V round charging socket. The five-foot cable provides practical reach between a wall outlet and a toy parked in a playroom, garage, or patio.
Compatibility with several ride-on models makes it useful for households sharing toys across children, although the connector shape still needs checking. It has no practical role in a Slash 4×4 because RC packs and toy-vehicle sockets differ.
The Value In It
- A 12V output targets common kids ride-on vehicles.
- The round socket fits supported Best Choice Products models.
- A five-foot cable eases charging away from the wall.
- The same charger can serve multiple compatible toys.
Less Ideal Details
- The round connector differs from a Slash battery connection.
- The 1A output charges more slowly than higher-current options.
- Households need to check the toy’s socket shape and voltage.
Built For Families
You’ll find this charger convenient for parents maintaining supported 12V round-port ride-on vehicles.
Where A Sibling Pick Shines
The ToiCottage square-adapter kit offers a better fit when the ride-on vehicle uses the included square socket.
The square connector is the deciding feature here. It pairs a 12V charger with a battery-side adapter, making it useful for ride-on toys that accept the matching red socket instead of the round connection used by the previous ToiCottage model.
Red and green status lights distinguish charging from a completed charge, which helps during routine toy care. You must still verify the socket, voltage, polarity connection, and battery condition before repeated use.
Everyday Wins
- The square battery adapter supports a distinct toy connection.
- A replaceable 15A fuse adds circuit protection.
- Red and green indicators show charging status.
- The kit combines charger and battery connector.
Worth Bearing In Mind
- Only 12V batteries are supported.
- The square socket must match the vehicle connection.
- A neglected battery may require checking before charging.
- This setup does not fit a Slash 4×4 RC battery.
Important Details
Whose Shelf It Belongs On
You’ll want this kit for a compatible square-port 12V children’s ride-on vehicle.
Swap It Out When
Choose the ToiCottage round-port charger instead for a supported ride-on vehicle with a circular socket.
What Matters Before Powering Your Slash
Start with the Slash battery specification rather than a broad charger listing. A standard 1/10 Slash 4×4 uses a three-cell LiPo pack with a nominal voltage of 11.1V, so charging equipment must support that cell count and chemistry.
Match Cell Count And Chemistry
XT60 identifies the high-current connector, not the charger chemistry. Your charging setup still needs proper LiPo support, balancing where required, and a connection method that fits both the charger lead and battery.
Confirm Physical Connectors
Connector names such as XT60, Traxxas-style, round, and square describe different interfaces. Measure or inspect the existing connection rather than relying on the vehicle’s model name, since adapters can be misleading.
Treat Non-Electrical Parts Differently
The Integy driveshafts and suspension kit are Slash accessories, not battery or charging equipment. They may strengthen or personalize the platform, but neither can replace a compatible pack.
Common Mistakes To Avoid
Battery and charger listings often mix RC vehicles with children’s ride-on toys because both use “12V” somewhere in the description. That wording does not make their batteries interchangeable.
Check the cell count, chemistry, voltage, connector shape, and polarity before connecting anything. A Slash 3S LiPo setup should not be placed on a lead-acid maintainer, and a 12V ride-on charger is not automatically suitable for an 11.1V RC pack.
What The Higher Tier Buys
Broader voltage selection, adjustable charging current, and more chemistry support make a multi-purpose charger useful across several lead-acid vehicles. Those features cost more in setup complexity because you must select the correct mode and verify the battery type.
For a single Slash, added charger versatility does not replace the essentials: balanced LiPo charging, proper cell support, and a sound connector arrangement. Pay for those functions rather than headline output alone.
Frequently Asked Questions
What Battery Does A Traxxas Slash 4×4 Use?
A standard Slash 4×4 uses a three-cell LiPo battery rated at 11.1V nominal. Verify your specific model and connector before replacing an existing pack.
Can An XT60 Charger Charge A Slash Battery?
An XT60 connector does not identify the charger chemistry. The charger must support three-cell LiPo charging and connect correctly to the battery’s charging lead.
Can A 12V Charger Maintain A Slash Battery?
A basic 12V lead-acid maintainer is generally unsuitable for a three-cell LiPo pack. Use equipment designed for LiPo chemistry and the Slash’s cell configuration.
Do The Integy Parts Charge The Slash?
The Integy driveshafts and suspension kit support mechanical or cosmetic upgrades. Neither part stores energy or charges a battery.
Are Kids Ride-On Chargers Compatible?
Only a ride-on vehicle with matching voltage, connector, and polarity can use these chargers. The round-port and square-adapter options serve different socket styles.
Final Verdict
The PowerHobby 3S 11.1V 5200mAh pack is the relevant Slash 4×4 power choice here, paired with a properly configured LiPo balance charger. The Integy parts serve mechanical upgrades, while the remaining chargers target 12V lead-acid or children’s ride-on vehicles rather than the Slash platform. Confirm chemistry, cell count, and connector geometry before purchase.
