Overlander 1100mAh 3S Airsoft LiPo Battery OL-3697

Power up your AEG with reliable, high-performance energy.
This 1100mAh 3S 11.1V LiPo stick battery delivers consistent power and rapid trigger response, making it perfect for CQB and outdoor airsoft gameplay. Designed to fit a wide range of AEGs with stick-type battery compartments — including buffer tubes, handguards, and top-wired receivers.

• Higher voltage and faster cycle — Being a 3S (11.1 V) pack, it offers increased voltage compared to typical 2S (7.4 V) packs, which can result in faster trigger response or higher rate-of-fire in some AEG setups (so long as the internals can handle it).
• Compact capacity suited to lightweight builds — With a moderate 1100 mAh capacity, it helps keep the battery size, weight and footprint small. That makes it ideal for setups where internal space is limited (e.g., short handguards or compact gearboxes) while still giving a decent skirmish duration.
• Good for upgraded internals or high-draw setups — LiPo batteries inherently support higher discharge rates than older NiMH/NiCd packs. LiPo batteries … have a higher discharge rate … leading to improved motor speed and Rate of Fire.” So if your gearbox or motor is drawing more current, a LiPo like this helps supply it.
• Brand reliability and build quality benefits — The manufacturer Overlander has a good reputation for matched cell packs and quality construction

• Capacity: 1100mAh – providing excellent runtime without excessive bulk.
• Configuration: 3S (11.1V) – delivers increased rate of fire and snappier response for high-performance AEGs.
• Connector Type:  Mini Tamiya/Deans
• Discharge Rate: 20C Constant/40C Burst for consistent output under load.
• Dimensions: 102mm x 21mm x 17mm – important for fitting into stocks or handguards
• Weight: 67g

• Use only with compatible airsoft devices. Check voltage and connector compatibility before use.
• Use a Compatible LiPo balance Charger Only designed for 3S (11.1V) batteries
• Always refer to the safety instructions before charging or use.
• Do not overcharge or over-discharge. Always use a LiPo-compatible balance charger.
• Never leave the battery unattended while charging or connected to a device.
• Inspect regularly for damage, swelling, or punctures. Discontinue use immediately if damaged.
• Avoid exposure to heat, fire, or water. Store in a cool, dry place away from direct sunlight.
• Charge on a non-flammable surface and keep away from flammable materials.
• Do not short-circuit, crush, or modify the battery or its wiring.
• Disconnect after use. Never store the battery connected to your airsoft gun.
• Store partially charged (around 50%) if not in use for long periods.
• Dispose of properly at a certified battery recycling or disposal facility — do not throw in household waste.

Important notice: Given that this battery is 11.1 V (12.6V when fully charged), you must ensure your airsoft gun’s internals (motor, gearbox, wiring, safety circuit, etc.) are capable of handling this higher voltage. Many stock AEGs recommend a lower voltage because using a 3S lipo pack could overstress components.
