Lancer Tactical 11.1V 1200 mAh 15C Mini LiPO Battery, Deans, Black

This is a compact 11.1V LiPO pack built for AEGs where a full-size stick or butterfly won't fit. The "mini" shape is narrow enough for slim buffer tubes and tight stock cavities that reject thicker packs. If your gun's battery compartment is cramped, this is the shape that gets inside.

11.1V is 3S (three cells in series). The extra voltage over 7.4V means faster cycle speed and snappier trigger response — but only on a gun wired with a MOSFET. Running 11.1V through stock mechanical trigger contacts is how you burn them out. The MOSFET moves the heavy current off the contacts and onto a component designed for it. Without one, stick to 7.4V.

Capacity is 1200 mAh. That is on the lower side, which is the trade-off for the small footprint. You'll need to plan your battery rotation around game length — a couple of skirmishes per charge is a reasonable expectation for full-auto play. The 15C discharge rating means it can deliver up to 18 amps continuous, which is more than enough for any standard AEG spring setup.

Connector is a mini Deans (mini T-plug) — the most common plug in the hobby. If your gun uses a different connector, a mini-Deans adapter is inexpensive and widely available.

Charge only with a LiPO balance charger. A standard smart charger will destroy the battery and can cause a fire. Battery and charger are sold separately. Store between 35 and 70 degrees F, away from direct sunlight or heat sources. Never store a LiPO fully charged or run it completely flat — both degrade the cells over time.
