Specna Arms LiPo 11,1V 1300mAh 15/30C Battery Butterfly Configuration T-Connect (Deans)


A reliable power supply is essential for the performance of any AEG. The Specna Arms LiPo 11.1V 1300mAh 15/30C Battery – Butterfly Configuration – T-Connect (Deans) combines high capacity with a compact butterfly shape, making this battery ideal for replicas with a battery compartment in the handguard or crane stock. Thanks to the efficient Deans (T-Connect) connector, you also benefit from lower resistance and better current transfer than with traditional Tamiya connectors.
Why choose an 11.1V LiPo?
An 11.1V LiPo battery delivers significantly more power than a standard NiMH battery or a 7.4V LiPo. The higher voltage ensures a faster trigger response, a higher rate of fire and more consistent motor performance. Replicas fitted with a MOSFET or reinforced internal components, in particular, benefit most from an 11.1V power source.
During both CQB and outdoor skirmishes, you’ll notice that the replica responds more immediately and is ready for the next shot more quickly.
Butterfly configuration for maximum flexibility
The butterfly configuration consists of two narrow battery cells that can easily be fitted on the left and right inside a crane stock or handguard. This makes the battery suitable for replicas where a traditional stick or block battery simply won’t fit.
This design offers a great deal of flexibility without compromising on capacity or performance, and makes the battery suitable for a wide range of M4, AR15 and other AEG platforms.
1300mAh capacity for longer days of play
With a capacity of 1300mAh, this battery provides enough power for most full days of play. You’ll need to change the battery less often, whilst retaining its compact size.
For players who regularly take part in longer skirmishes, this capacity offers an excellent balance between size, weight and battery life.
What does 15/30C mean?
The 15C continuous discharge rating provides a stable power supply during normal use, whilst the 30C peak discharge makes additional power available when the replica temporarily requires it.
This results in smooth gearbox operation, a stable trigger response and reliable performance during rapid-fire bursts.
The advantages of a Deans (T-Connect) connector
More and more airsoft players are switching to Deans connectors because of their superior electrical performance. Compared to Mini Tamiya connectors, a Deans connector offers lower resistance, resulting in less energy loss between the battery and the motor.
This results in more efficient power transfer, a more immediate trigger response and less heat build-up during intensive use.
Do check whether your replica comes with a Deans connector as standard or has been converted before you purchase this battery.
Reliable LiPo technology
LiPo batteries are renowned for their excellent capacity-to-size ratio. Despite their compact dimensions, they deliver a high power output and maintain a stable voltage throughout virtually the entire discharge cycle.
Furthermore, LiPo batteries do not suffer from the memory effect. This means you can recharge the battery at any time without this having a negative impact on its performance. With correct use and storage, a high-quality LiPo battery will last for hundreds of charge cycles.
Safe use and maintenance
To maximise the battery’s service life, it is important to charge it only using a suitable LiPo balancer charger. Ensure that the voltage never falls below 3.0 volts per cell and never charge the cells beyond 4.2 volts per cell.
If you are not going to use the battery for a prolonged period, storing it at approximately 3.8 volts per cell (storage charge) is the best option. This ensures that the chemical composition of the cells is maintained at an optimal level and prevents any loss of capacity.
Compatibility
This battery is suitable for replicas with a Deans (T-Connect) connector and sufficient space for a butterfly configuration, including:
- M4 Crane Stocks
- The AR15 platform
- Replicas with a handguard battery compartment
- CQB-builds
- AEG's met MOSFET of ETU
- Various Specna Arms replicas
Always check the available space and the connection for your replica before choosing a battery.

Common mistakes
A common mistake is charging a LiPo battery with a standard NiMH charger. Always use a suitable LiPo balancer charger to prevent damage to the battery cells.
People also often forget to store the battery on a storage charge when it is not going to be used for a long time. This can significantly reduce its service life.
You should also always check that your replica is compatible with an 11.1V LiPo battery before using it.
Frequently Asked Questions
Is this battery suitable for all AEG models?
No. This battery is intended for replicas that are compatible with an 11.1V LiPo and feature a Deans (T-Connect) connector.
What is the advantage of a Deans connector?
A Deans connector offers lower electrical resistance than a Mini Tamiya, which means that current is transferred more efficiently and the replica responds more quickly.
Will this battery fit in a Crane Stock?
Yes. Thanks to its butterfly configuration, this battery has been specially designed for crane stocks and similar battery compartments.
How do I charge this battery safely?
Always use a LiPo balancer charger and charge the battery only at the specified voltages.
How long does a LiPo battery last?
When used, stored and maintained correctly, the average service life is approximately 500 to 700 charge cycles.
