Description
Introducing the Acebeam 18650 3000mAh Rechargeable Li-ion Battery. A high-drain power cell engineered for demanding illumination devices that require both strong output and reliable endurance. Built on a 3.6V lithium-ion platform, it delivers a balanced combination of capacity and discharge capability, making it well-suited for high-performance flashlights and tactical lighting systems. With a 3000mAh capacity, it provides dependable runtime while maintaining the ability to support intense power demands when needed.
A key strength of this battery lies in its high discharge performance. It supports a continuous discharge current of 15A and can deliver short bursts of up to 20A, enabling it to power extremely bright devices such as the ACEBEAM X20 Searchlight, which can reach outputs of up to 10,000 lumens. Despite this high output capability, it can also sustain efficient low-output operation, offering extended runtimes-such as up to 28 hours at lower brightness levels-making it highly adaptable to different usage scenarios. Convenience and safety are central to its design. The integrated USB-C charging port allows the battery to be recharged directly without requiring a dedicated external charger, offering flexibility for users in the field or on the move. Internally, it features protection circuitry that safeguards against common risks such as overcharging, over-discharging, overheating, and short circuits. This layered safety design is further supported by high-power MOSFET components and a stainless steel shell construction, which improves durability and structural integrity.
Physically, the battery follows the standard 18650 form factor, measuring approximately 70.6 mm in length and 18.6 mm in diameter, with a lightweight design of around 49 grams. Its button-top configuration ensures compatibility with a wide range of ACEBEAM devices, including models such as the P16 2.0, X20-R, M2-X, L17, L19 1.0, K75 2.0, and G15. Environmentally conscious design also plays a role, as it is free from mercury, lead, and cadmium, and supports up to approximately 500 charging cycles. Overall, this battery offers a strong balance of power, safety, and practicality for high-performance lighting applications.
Please Note: Charging Cable Not Included.
