Without a battery, your AEG is a £400 paperweight. Two main chemistries — LiPo for power, NiMH for safety — plus specialist options for older rifles and electronics.

Every AEG, every electric speedloader, every BLU-Link and BLINC FCU, every tracer unit, every red dot sight needs power. For AEGs specifically, the battery is the second-most-important spec after the rifle itself — undersized and the rate of fire drops, oversized and you risk gearbox damage, wrong connector and it doesn't plug in at all. Getting this right matters.

The two mainstream chemistries split clearly. LiPo (Lithium Polymer) is the modern standard — higher discharge rate, more power per gram, the chemistry that lets a stock AEG run faster than its mechanical limits without bogging down. The trade-off is care — LiPos need a smart charger, can't be deep-discharged, and require occasional balance charges. NiMH (Nickel Metal Hydride) is the older safe-default — gentler chemistry, more forgiving of poor charging habits, the right choice for new players who haven't yet learned battery care. Slower trigger response, more weight per joule of power stored, but far harder to damage.

Other batteries covers everything that isn't LiPo or NiMH — Li-Ion cells for specialist applications, batteries for tracer units, button cells for sights, and the AA/AAA loadouts for electronic accessories. Whichever chemistry you choose, you'll also need chargers matched to it (LiPo balance chargers don't work for NiMH and vice versa) and the right cables and connectors for your rifle's wiring.

💡 Titan Forge tip: Match the connector to your rifle BEFORE the day before a game. T-plug (Deans) is the standard, Tamiya is the AEG legacy default, mini-Tamiya fits some SMGs and compact AEGs. Get the wrong one and your rifle doesn't connect to the battery — and replacement adapters cost more than the time-saving of buying the right one first.
