5 Top Rechargeable Cells for Tamiya Mini 4WD
These rechargeable cells are ranked by runtime, voltage stability, fit, and value, counting down to the top pick.
5. Cecicebb Airsoft Rechargeable Battery Pack
Best for: Airsoft players needing spare batteries
The Cecicebb pack includes two rechargeable 7.4V batteries rated at 1,800mAh each. Each battery measures about 2.83 by 0.73 by 0.43 inches and uses a Mini Tamiya plug, which fits many popular airsoft rifles and other compatible models. A 30C discharge rating supports steady power delivery for setups that need more current than basic stock packs.
The package also includes one 7.4V USB charging cable. Its built-in protection circuit helps manage charging, while the indicator light shows charging status. At around $19, this two-pack costs less than buying two separate replacement batteries. The main value comes from having a backup ready when the first pack runs low. Still, buyers should confirm the rifle’s battery compartment dimensions and connector before ordering. The listed details do not provide a charging time or expected cycle count, so performance over long-term use remains unclear.
Pros
- Two 1,800mAh batteries provide a spare for longer game days.
- Compact 2.83-inch length fits many small airsoft battery compartments.
- 30C discharge rating and Mini Tamiya plug suit many compatible rifles.
Cons
- One USB charging cable must be shared between both batteries.
- Compatibility is not universal, and the listed size may not fit every stock or handguard.

Compatibility covers several 1/18 trucks, including DEERC 9310YL, 9300, 9301E, 9303E, 9304E, and 9305E models. It also lists Bezgar HM181 and HS181 vehicles, older Vcanny and FUNTECH cars, Ezone PX9300-series trucks, and some Mostop 1/12 tanks using the same plug. The T-plug adapters add flexibility for compatible vehicles. Buyers must check the battery bay and connector before ordering. The mini Tamiya plug measures about 10 x 5.5mm, and polarity matters: the red wire connects to the square hole, while the black wire connects to the round hole.
Pros
- Two 1,200mAh batteries provide a spare for longer driving sessions.
- Two USB cables let you charge both packs separately.
- Included T-plug converters support compatible RC models with Deans-style connections.

- The 58mm battery length and mini Tamiya polarity may not fit every RC vehicle, even within the listed model families.
3. Tamiya 55120 Mini 4WD Battery Power Set
Best for: Mini 4WD racers needing fresh cells
The Tamiya 55120 Battery Power Champ RX is a 12-piece set of alkaline batteries for Mini 4WD cars. It targets moments when a motor needs higher current, such as a starting dash or ramp climb. Compared with the Power Champ RS, this version offers stronger current discharge capability. That makes it better suited to short, demanding bursts than basic use. At around $20, the pack may suit racers who want matching batteries ready for several sessions.
A leak-resistant design helps protect stored batteries in a toolbox or drawer. Tamiya also states that these cells maintain better discharge performance after long storage, though age, temperature, and motor load still affect results. Their use extends beyond Mini 4WD cars. They can also power Star Unit series products and compatible transmitters. This is a disposable alkaline option, not a rechargeable battery system. Check your equipment’s required battery size before ordering, since the listed details do not confirm every device’s fit.
Pros
- Higher current discharge can help with fast starts and steep ramp climbs.
- Leak-resistant construction makes storage less risky.
- Twelve batteries can cover several cars, accessories, or transmitters.
Cons
- These are single-use alkaline batteries, so ongoing replacement costs can add up.
- The 12-pack may be more than casual users need, especially for one car.
2. Tenergy 9.6V NiMH Battery Pack and Charger
Best for: AEG owners needing a replacement pack
This Tenergy set combines a charger with a 9.6V, 1600mAh NiMH battery pack for airsoft electric guns. The pack uses eight 2/3A NiMH cells in a butterfly layout and weighs 6.7 ounces. Each section measures about 20mm in diameter and 117mm long, so checking the battery compartment remains essential. That matters even more for upgraded or modified AEGs.
The included charger works with compatible 6V to 12V RC batteries, giving buyers a charging option in the same package. A mini Tamiya connector connects to many electric airsoft rifles, and the assembly uses 16-gauge wire. The 1600mAh capacity should provide useful field runtime, though the listing does not state an exact duration or charge time. Compatibility includes common platforms such as M4, M14, M249, G36, AUG, G3, MP5, RPK, and others. At around $35, this set costs more than a battery alone, but it can reduce the need to buy a separate charger.
Pros
- Includes both the 9.6V battery and compatible charger.
- Eight NiMH cells provide a rechargeable 1600mAh power source.
- Mini Tamiya plug fits many popular AEG platforms.
Cons
- The 20mm by 117mm sections may not fit every stock or handguard.
- Exact charge time and field runtime are not provided.
1. Blomiky 9300 850 2 Rechargeable Li-Po Battery
Best for: 1/18 RC owners needing spare batteries
The Blomiky 2-pack provides two 7.4V, 850mAh, 2S Li-Po batteries for compatible 1/18-scale RC cars and trucks. Each pack stores 6.29Wh, measures about 2.16 by 1.20 by 0.61 inches, and weighs 1.8 ounces. The package also includes two USB cables and two Mini Tamiya-to-Deans T adapter cables.
Compatibility covers several DEERC, BEZGAR, FUNTECH, Ezone, Rcabcar, and similar models, including the 9310, 9301E, 9302E, 9303E, and 9305E. Still, check your car’s connector and battery compartment before ordering. The Mini Tamiya plug uses one square hole and one round hole, with a plug section measuring about 0.4 by 0.22 inches.

Buying Guide
Voltage and physical fit matter most when choosing power for a Tamiya Mini 4WD car. Most models use two AA-size cells, so a 2.4V NiMH setup must fit the holder without stressing the contacts or chassis.
- Battery chemistry: Choose rechargeable NiMH cells rated at 1.2V each. Avoid unverified lithium-ion cells, which can supply the wrong voltage and require different charging equipment.
- Capacity: Look for 800-1,000mAh for a useful balance of runtime and weight. Cells above 2,000mAh may weigh more without improving a lightweight race car.
- Discharge performance: Select cells designed for high-drain devices, with a stated discharge rating when available. This helps motors maintain power during acceleration and uphill sections.
- Size and weight: Confirm standard AA dimensions, about 50.5mm long and 14.5mm wide per cell. Keep total battery weight near 50-60 grams if quick handling matters.
- Charger and pack count: Buy a two- or four-cell pack with a NiMH charger that stops automatically. A smart charger should complete charging in roughly 2-4 hours, depending on capacity.
If you cannot have everything, prioritize correct voltage, AA fit, and a secure connection over maximum capacity.
Frequently Asked Questions
How many rechargeable batteries does a Tamiya Mini 4WD need?
Tamiya Mini 4WD cars use two rechargeable AA NiMH batteries, producing 2.4 volts together. Choose matched cells with similar capacity and charge them as a pair. Low-self-discharge models rated around 1,900 to 2,500 mAh fit many stock battery compartments and work well for repeated racing sessions.
What capacity is best for Tamiya Mini 4WD batteries?
The most practical capacity for a Mini 4WD rechargeable battery is 1,900 to 2,500 mAh. Cells near 2,000 mAh offer a useful balance between runtime, weight, and charging time. Higher capacity does not automatically mean more speed, since motor condition, gearing, tires, and track layout also matter.
Can I use lithium rechargeable batteries in a Tamiya Mini 4WD?
You can use rechargeable AA NiMH cells, but lithium-ion AA batteries are not a direct substitute unless the car’s instructions specifically allow them. Most Mini 4WD models expect two 1.2-volt cells. Lithium batteries may use different voltage control, so stick with NiMH in a standard two-cell holder.
Are low-self-discharge NiMH batteries good for Mini 4WD racing?
Low-self-discharge NiMH batteries are usually the better choice for Mini 4WD racing because they retain charge during storage. A quality pair rated near 2,000 mAh can remain ready for weeks between sessions. Use a charger made for NiMH cells, and avoid mixing old and new batteries.
Conclusion
Blomiky 9300 850 2 Rechargeable Li-Po Battery is the top pick for Tamiya Mini 4WD racers who want a rechargeable option for regular track sessions. It suits buyers seeking a repeat-use setup, provided their car and charger support this battery type. If your priority is simpler battery handling, choose a compatible NiMH pack instead, since it uses a familiar chemistry and may fit your charging routine better. Before buying, double-check the battery’s size, connector, Mini 4WD compatibility, included quantity, charger requirements, and current price. Those checks help prevent ordering a pack that will not fit the chassis, connect to the car, or match the equipment already on your workbench.
