SA Li-Pol battery 11.1V / 1300mAh, 15 / 30C (T-Dean) – Crane (127 mm)

Specna Arms 11.1V Li-Po battery

This expert product description was prepared by the ANAREUS.cz expert team. All rights to this unique content are bound to the anareus.cz domain.The Specna Arms 11.1V Li-Po battery offers a 15 / 30C discharge rate, providing fast trigger response and a high RoF for AEG guns. Thanks to its 1300 mAh capacity, it offers sufficient endurance for gameplay while retaining the compact dimensions of the 3-piece Crane configuration. The battery is suitable, for example, for a Crane Stock or a more spacious handguard. Li-Po technology provides stable performance even when temperatures drop and a long service life with proper maintenance. The battery is equipped with a balance connector for safe charging, and the manufacturer recommends a Li-Po charger with a power output of 25 W or more. The 11.1V battery is suitable for AEG rifles, SMGs, machine guns and DMRs equipped with an ETU, processor unit or MOSFET. It is not intended for long-term use in guns with basic wiring and mechanical trigger contacts, where the higher electrical load causes contact arcing and burning.

Warnings

• Charge the Specna Arms 11.1V battery only with powerful chargers rated at 25 W or more (e.g. Gens ACE iMars Mini 60W / iMars S100 / iMars D300 and D1000 or TITAN Digital Charger V2) to prevent battery damage.
• Low-power 10W chargers such as the IMAX B3 or Gens Ace iMars S10 do not provide sufficient power to charge 11.1V batteries, which may result in battery damage that is not covered by the warranty.
• The 11.1V battery is not intended for long-term use in guns with basic wiring and mechanical trigger contacts, where the higher electrical load causes contact arcing and burning.
• For a long service life of the gun, we recommend using an 11.1V battery only with models equipped with an ETU processor unit or MOSFET.
• Always check the available space inside the gun before ordering.
• Do not use a mechanically damaged, swollen or otherwise deformed Li-Po battery.

Maintenance, charging and storage instructions

• To ensure optimum performance, we recommend regular battery maintenance.
• Before first use, fully charge the battery at a lower current and then follow the charging instructions supplied with the battery.
• Avoid overloading and deep discharge to extend battery life.
• For long-term storage, keep the battery at approximately 75% capacity.
• Charge the battery only with a suitable Li-Po battery charger with a power output of 25 W or more, ideally inside a protective charging bag.
• Store it in a cool, dry place away from direct sunlight and extreme temperatures.
• Never fully discharge the battery.
• Stop using the battery when the RoF or gun response begins to drop significantly, or when the ETU unit identifies it as discharged or faulty.
• Always disconnect the battery from the gun after the game.

Frequently asked questions from our store

What power level of AEG guns is this 11.1V battery suitable for?

This battery is suitable for AEG guns with a power of over 1.7 Joules, approximately 130+ m/s, equipped with an ETU unit or MOSFET. Its specific suitability also depends on the motor, spring, gears and overall configuration of the gun.

Can I use an 11.1V Li-Po battery in a gun without a MOSFET or ETU?

For long-term use, we do not recommend it. The higher electrical load of an 11.1V battery can cause arcing and burning of mechanical trigger contacts in basic wiring. This battery is therefore intended primarily for guns with an ETU processor unit or MOSFET.

What is the difference between a 7.4V and 11.1V Li-Po battery?

A 7.4V battery uses 2 cells (2S), while this 11.1V battery has 3 cells (3S). The higher voltage generally provides faster trigger response and a higher RoF, but also places greater stress on the electrical and mechanical parts of the gun. We therefore recommend an 11.1V battery for appropriately equipped AEGs.

What charger do I need for this 11.1V Li-Po battery?

Use a charger designed for 3S Li-Po batteries with balance charging and a power output of at least 25 W. The manufacturer does not recommend low-power 10W chargers such as the IMAX B3 or Gens Ace iMars S10.

How should I store an 11.1V Li-Po battery correctly?

For longer periods without use, store it at approximately 75% capacity, disconnected from the gun, in a cool, dry place away from direct sunlight and extreme temperatures. Never fully discharge the battery and do not use it if it is swollen or mechanically damaged.
