HiMAXBATT 11.1V 5Ah Rechargeable 18650 Li-ion Battery Pack for Light Fixture, Monitoring

Premium Lithium-Ion Energy Density & Safety

Powered by high-performance lithium-ion 26650 cells (5000mAh each) in a 3S1P configuration, this 11.1V 5Ah lithium-ion battery pack delivers unmatched energy density for prolonged operation. Featuring a built-in lithium-ion BMS (Battery Management System), it ensures critical protections against overcharge, over-discharge, and short circuits — adhering to UL-certified lithium-ion safety standards — while maintaining 80% capacity retention after 1000+ cycles. Ideal for drones, robotics, and high-end electronics requiring reliable Li-ion power solutions.

Precision Lithium-Ion Power Management

Engineered for high-drain lithium-ion applications, this pack supports 10A continuous discharge (20A peak) with ultra-low voltage drop, perfect for industrial tools and medical devices. Its 2.5A lithium-ion fast-charging circuit with cell balancing reduces full charge time to 3.5 hours, backed by temperature-resistant PCM technology (-20°C to 60°C) for stable lithium-ion performance in extreme environments. All connections use laser-welded nickel tabs to minimize Li-ion internal resistance and maximize efficiency.
