What Is a Nunchuck Airsoft Battery?
A nunchuck battery is a rechargeable battery pack divided into two linked sections. The split design allows one section to sit in each side of an airsoft guns crane stock, with the wiring and connector positioned around the central stock tube.
This layout is especially common on rear-wired M4 AEGs. Compared with a brick or stick battery, the two-part design can make better use of the narrow spaces inside a retractable stock.
What Is an Airsoft Crane Stock Battery?
An airsoft crane stock battery is simply a battery designed to fit inside the side compartments of a crane-style stock. Most crane stock batteries use a nunchuck configuration, although slim stick batteries may also fit some designs.
Crane stocks are popular because they combine an adjustable length of pull with enough space to store a battery internally. Fit varies between stock designs, so always compare the battery dimensions with the available compartment space.
Airsoft Crane Stock Battery Types
NiMH Nunchuck Batteries
NiMH crane batteries are durable, straightforward to charge and commonly used in standard AEGs. Popular examples include 8.4V and 9.6V nunchuck airsoft batteries, often with capacities around 1600mAh or higher.
A 9.6V NiMH pack can provide stronger trigger response than an 8.4V battery while remaining a familiar choice for many factory AEGs.
7.4V LiPo Crane Batteries
A 7.4V LiPo battery for an airsoft crane stock offers compact dimensions, efficient power delivery and responsive performance. It is a popular upgrade for many standard AEGs, provided the rifle is suitable for LiPo use.
LiPo batteries must be charged with a compatible balance charger and inspected regularly for swelling or damage.
11.1V LiPo Nunchuck Batteries
An 11.1V LiPo nunchuck airsoft battery can deliver faster trigger response and a higher rate of fire. This voltage should only be used in an AEG with suitable internals and electronics, ideally including a properly rated MOSFET.
Using an 11.1V battery in an unsuitable rifle may increase wear, overspin, heat and stress on the gearbox.
Li-Ion Crane Batteries
Selected crane stock batteries use lithium-ion cells. These packs can offer useful capacity and long run times while retaining a split shape that suits many adjustable stocks.
Use a charger approved for the exact battery chemistry and voltage, and follow the manufacturer’s charging and storage guidance.
Choosing the Correct Voltage
| Battery Type |
Typical Use |
Key Considerations |
| 8.4V NiMH |
Entry-level and standard AEGs |
Straightforward power delivery and simple maintenance. |
| 9.6V NiMH |
General skirmishing |
Can improve response compared with an 8.4V pack. |
| 7.4V LiPo |
Many standard and upgraded AEGs |
Compact and responsive; requires a LiPo balance charger. |
| 11.1V LiPo |
Suitable upgraded AEGs |
Higher performance with increased stress on components. |
Airsoft M4 Crane Stock Batteries
An airsoft M4 crane stock battery is commonly used in rear-wired M4 and M16 AEGs. The two battery sections fit into the side tubes of the stock, while the connector and wiring sit around or behind the buffer tube.
Not every M4 crane stock has the same internal dimensions. Some are designed for slim LiPo packs, while others can accept larger NiMH nunchuck batteries. Check both the battery size and the cable routing before ordering.
Crane Stock Battery Installation
- Disconnect the existing battery and make sure the AEG is safe.
- Extend or remove the stock according to the manufacturer’s instructions.
- Place one side of the nunchuck battery into each stock compartment.
- Route the wiring carefully without pinching or sharply bending it.
- Connect the battery using the correct plug type.
- Refit the stock and confirm it can move without trapping the wires.
Do not force an oversized battery pack into the battery compartment. Crushed cells, damaged insulation or pinched wiring can create a serious safety risk.
Connector Compatibility
Nunchuck airsoft batteries are commonly supplied with Mini Tamiya or Deans connectors. Choose the plug that matches your AEG unless the rifle has been professionally rewired or a suitable adaptor is used.
- Mini Tamiya: Common on factory AEGs and traditional NiMH batteries.
- Deans or T-Plug: Compact and popular on upgraded AEGs.
- Other connectors: Used on selected specialist platforms; check before purchasing.
Battery Capacity and Compartment Size
Capacity is measured in milliamp-hours, shown as mAh. A higher mAh rating will generally provide more shots per charge, but it may also make the battery physically larger.
An airsoft crane stock with a battery compartment has limited space around the buffer tube. Measure the usable width, height and length of both side channels, allowing enough room for the wiring and connector.
Nunchuck vs Stick vs Brick Batteries
| Battery Shape |
Best Suited To |
Main Advantage |
| Nunchuck or Crane Battery |
Crane stocks and split compartments |
Uses both sides of the stock for efficient battery storage. |

Buying Advice
- Confirm that your bb guns stock has two usable battery compartments.
- Measure the available space before selecting a battery.
- Check the recommended voltage for your AEG.
- Match the battery chemistry to the correct charger.
- Confirm whether the rifle uses Mini Tamiya or Deans connectors.
- Allow enough space for safe cable routing.
- Do not use an 11.1V LiPo unless the AEG is designed for it.
Charging and Care Tips
- Use a charger approved for the battery chemistry and voltage.
- Never leave a charging battery unattended.
- Do not use packs that are swollen, punctured or damaged.
- Disconnect the battery from the AEG after each game.
- Keep wiring away from sharp edges and moving stock components.
- Allow a warm battery to cool before charging.
- Store lithium batteries at the recommended storage voltage.
- Keep batteries in a cool, dry place away from direct heat.
Frequently Asked Questions
What is a nunchuck airsoft battery?
A crane airsoft battery is a split rechargeable pack with two linked cell sections. It is designed to fit around the central tube inside many crane stocks.
Is a nunchuck battery the same as a crane battery?
Usually, yes. The terms nunchuck battery and crane stock battery commonly describe the same split battery format.
Will a nunchuck battery fit my crane stock?
Only if the two battery sections fit inside the stock compartments and the connector, voltage and chemistry are compatible with your AEG.
What battery fits an airsoft M4 crane stock?
Many M4 crane stocks accept split NiMH nunchuck batteries, slim 7.4V LiPo packs or selected 11.1V LiPo and Li-Ion batteries. Internal dimensions vary, so check the available space first.
Should I choose a 7.4V or 11.1V LiPo crane battery?
A 7.4V LiPo is suitable for many standard AEGs. An 11.1V LiPo offers faster performance but should only be used in an airsoft rifle with compatible internals and electronics.
Can I use a 9.6V nunchuck battery in my AEG?
Yes, if the AEG is rated for 9.6V NiMH power and the battery fits the stock. Check the manufacturer’s recommendations before use.
How do I install a battery in a crane stock?
Place one battery section into each side compartment, route the wiring around the buffer tube and connect the plug without pinching the cables.
Can I fit a large battery in a crane stock?
Only if the battery dimensions match the available space. Never force a large pack into the stock or compress the cells and wiring.
Do nunchuck batteries need a special charger?
The charger must match the battery chemistry. Use a NiMH Battery charger for NiMH packs and a compatible balance charger for LiPo batteries.
Why is my crane stock pinching the battery wires?
The cable may be routed too close to the stock adjustment mechanism or the battery may be oversized. Reposition the wiring and check that the stock can move freely before use.
What is the best airsoft nunchuck battery?
The best option is one that matches your AEG’s voltage, connector and battery compartment while providing enough capacity for your usual game day.
