How to choose a battery for an airsoft replica?

The choice of the right battery depends on several factors: the replica’s platform, the type of stock, the connector type, and the available space in the stock or body.

Steps to choose a battery:

1. Check the platform of your replica (e.g. M4, AK) — this information can be found under the "Replica model" attribute in the product's technical specifications.
2. Determine where the battery is intended to be placed.
3. If the battery sits in the stock, identify the stock type. For AR-15‑style stocks, specify which type you have: no extra side compartments, with extra side compartments, or PDW‑style stock.
4. Identify the connector type you have (Small Tamiya or T‑connect/Deans).
5. Check whether the replica has a MOSFET/ETU — if it does, you can safely use an 11.1 V LiPo/Li‑ion battery; if it does not, we recommend a 7.4 V LiPo/Li‑ion battery.
6. Choose a battery that fits the available space in the stock or body.

Important battery parameters:
• Voltage (V) — affects the replica’s rate of fire and operating cycle.
 • Dimensions — must fit the space in the stock/body. Dimensions are usually shown in the product images and the “Specifications” section.

In our offer we list compatible batteries in each product description. If your replica is not listed, use the procedure above to select a suitable battery.

Connector type:
The most common ones are mini Tamiya (standard in many replicas) and T-Deans/Deans (a more efficient connector used in higher-end replicas).
 You can find information about the connector type in the product description on our website, in the Technical Data section. If the replica was not purchased in our store, below we show photos of the connectors so that you can easily match the battery to the connector.

Voltage (V):

A 7.4 V Li-Po/Li-Ion battery is recommended for replicas without a MOSFET, while an 11.1 V Li-Po/Li-Ion battery is recommended for replicas equipped with a MOSFET.

For replicas that come with a battery included, the set may contain 8.4V or 9.6V NiMH batteries. We recommend replacing them with a more efficient battery, such as a 7.4V Li-Po (it’s worth noting that Li-Po batteries offer high performance and compact size) or a 7.4V Li-Ion (keep in mind that Li-Ion batteries provide similar performance to Li-Po, but are larger in size — comparable to NiMH batteries).

Capacity (mAh):
 This determines how long you can play on a single charge. Higher capacity = longer gameplay time, but also a larger battery size. We offer batteries with capacities ranging from 1000 to 2200 mAh.

The most commonly chosen battery for replicas is a 1100 mAh Li-Po, which usually fits without any major issues. When choosing batteries with higher capacity, make sure to check how much space is available in your replica’s battery compartment and compare it with the battery’s dimensions listed in the technical specifications.

Dimensions and shape:
Different battery shapes are used in replicas: stick, nunchuck (split type, often used in Special Forces-style stocks), and block (cube-shaped).
 The most important thing is that the battery fits in its designated space (stock, handguard, or under the cover). You can find the exact dimensions in the technical specifications of the selected battery.
