Specna Arms 7.4V LiPo Battery 2600mAh 20/40C Tamiya Mini


Are you looking for a LiPo battery with an exceptionally long runtime for your airsoft replica? The Specna Arms LiPo 7.4V 2600mAh 20/40C Battery – Mini Tamiya offers a very high capacity in a sleek two-part design. Thanks to its 7.4V voltage, 2600mAh capacity, 20/40C discharge rate and Mini Tamiya connector, this battery is ideal for players who want to play for long periods without having to change batteries regularly.
Thanks to its two slim battery modules, this LiPo battery is easy to fit into various flasks and battery compartments where flexibility is required.
Why choose a 7.4V LiPo?
A 7.4V LiPo battery is the perfect choice for most standard AEGs. Compared to traditional NiMH batteries, a LiPo offers a more stable voltage, a faster trigger response and is lighter in weight.
Furthermore, a 7.4V LiPo places less strain on the internal components than an 11.1V battery, making it ideal for replicas without extensive internal upgrades.
Extra-high capacity for maximum playtime
With an impressive capacity of 2600mAh, this battery is one of the larger LiPo batteries in its class. This means you can play for considerably longer before you need to recharge or swap it.
For long skirmishes, milsim events or players who fire a lot of shots, this battery is an excellent choice.
Two-part design for greater installation flexibility
The battery consists of two identical modules, making it easier to fit into narrow battery compartments.
Each module measures approximately 123 x 19.7 x 11 mm, making the battery suitable for many M4 buffer tubes, crane stocks and other replicas with a split battery compartment.
Reliable 20/40C performance
The 20C continuous discharge rating ensures a constant power supply during normal use. The 40C peak discharge provides extra power when the replica requires it temporarily.
This results in:
- Constant trigger response.
- Reliable engine performance.
- Smooth operation of the gearbox.
- Suitable for standard and slightly upgraded AEGs.
The combination of high capacity and a stable discharge rate makes this battery suitable for a wide range of playing styles.
Mini Tamiya connector
The battery is fitted with a Mini Tamiya connector, a commonly used connector in the airsoft world.
This means the battery is directly compatible with many standard AEG replicas. Always check beforehand whether your replica has a Mini Tamiya connector.
The advantages of LiPo technology
LiPo batteries offer high energy density, delivering a high power output in a relatively compact form.
You’ll also enjoy a range of benefits:
- No memory effect.
- Low self-discharge of just 3 to 5 per cent per month.
- Constant voltage during use.
- Average service life of 500 to 700 charge cycles when properly maintained.
As a result, LiPo batteries are now the standard choice for many airsoft players.
Safe use and maintenance
Always use a suitable LiPo balancer charger and ensure that the voltage does not fall below 3.0 volts per cell. Never charge the battery beyond 4.2 volts per cell.
If you are not going to use the battery for a long time, store it at approximately 3.8 volts per cell (storage charge). This will help to significantly extend the battery’s service life.
For added safety, it is advisable to charge the battery in a LiPo Safety Bag and to use a LiPo alarm whilst playing.

Common mistakes
A common mistake is choosing a battery based on its capacity without checking the available space in the battery compartment. Due to its high capacity, this battery is larger than many standard LiPo batteries. You should therefore always check that the two modules fit properly into your replica.
In addition, a LiPo battery is sometimes completely discharged. This can cause permanent damage to the battery cells. You should therefore preferably use a LiPo alarm or a replica with low-voltage protection.
You should also always keep the battery on a storage charge when you are not using it for a prolonged period.
