High Power Lithium Battery

Power, Safety, and Endurance: Molicel’s Three Series

To meet the diverse and demanding needs of the global energy market, Molicel has engineered three distinct lithium-ion cell series. Whether your application requires maximum power output, absolute safety assurance, or optimized runtime, we have a specialized solution.

Here is a detailed look at our core product families: Ultra-High Power, Safety, and Medium Power cells, each designed to push the boundaries of what a high power lithium battery can do.

 

Ultra-High Power Lithium Battery

 

Why Molicel?

We build every high power lithium battery around one idea—move energy faster than anyone else. Our research & development team keeps pushing cell chemistry and tab configuration so our cells can take huge charge currents and give back sustained discharge without heat spikes. That is why electronic-mobility and space customers keep coming back. 

High capacity, long cycle life, and very low internal resistance sit at the heart of this work. Our INR-21700-P50B  measures only 12.8  mΩ, yet it still holds capacity after thousands of high-rate cycles. That balance means each high power lithium battery we ship delivers punch and durability. 

 

Ultra-High Power Cell Specifications

INR-21700-P50B  — Our Performance Pioneer

We designed the INR-21700-P50B for professionals who demand robust power and engineers focused on energy-dense storage applications. The cell pairs a 5.0 Ah high-energy capacity with a class-leading 60 A continuous output, empowering builders to optimize pack architecture without sacrificing runtime or power delivery.

• 60 A Continuous Discharge Current – Maintains stable voltage under high load, mitigating voltage sag.
• 5000 mAh Capacity – Delivers exceptional runtime within the compact 21700 form factor.
• 265 Wh/kg Energy Density – Achieves an optimal balance between high energy and high power.
• 5C Fast Charge Capability – Significantly reduces charging time and boosts operational efficiency.

Perfect fit for hyper EVs, racing sports cars, eVTOLs, 2 wheeled motorcycle racing, heavy lift drones, BBUs, and more.

 

Safety Lithium Battery

Why Molicel?

Molicel’s S Series ultra-high power cells are engineered with optimized long calendar life and low flammability, providing exceptional safety and discharge capabilities. We use high-thermal-stability separators that tame gas release and spread heat fast. Advanced tab and can designs work dynamically to keep temperatures flat, ensuring every cell leaves the production line with the same tight, high-quality specifications.

Those safety-first cells already sit inside baseband battery units, data center racks, and AI servers run by top cloud players. BBUs and critical infrastructure systems all trust the same chemistry because it rides through intense shock, vibration, and wide-ranging temperatures without drama.

 

Safety Cell Specifications

Our S Series is low-flammability. Nail penetration and overcharge tests end with no flame and only mild venting. Pressure stays stable, and capacity stays high after thousands of cycles. Each high power lithium battery in the line keeps that reliability shift after shift. 

Major cloud service providers spec the S Series for their ORv3 backup packs. The cells deliver full power at 90 A and hold safe temps, so server uptime is untouched during grid faults. CSPs trust our high power lithium battery design since it stays cool and online and keeps data safe.

 

Medium Power Lithium Battery

 

Why Molicel?

Our medium-power cells are engineered for maximum operational uptime, centered on ultra-long cycle life and high energy density. We maximize capacity while minimizing weight, achieving a lightweight design that delivers reliable performance for over 1000 cycles.This balance of endurance and high energy density perfectly suits for high-utilization scenarios like LEVs,drones and robot cleaner.

INR-21700-M65A—our go-to pack filler

We produced the M65A for makers who need both miles and muscle. It combines a 6.5 Ah can with class-leading 25 A-plus discharge yet still hits 325 Wh/kg, which delivers drones longer flight and scooters longer rides—all from one high power lithium battery. 

• 25.6 A discharge current – keeps voltage flat under load.
• 6500 mAh capacity – stretches runtime in the same slot. 
• 325 Wh/kg energy density – trims weight for airframes. 
• Up to 1000 cycles – holds charge over many workdays.
• Ideal for drones, LEVs, e-scooters, and robot vacuums – one cell, many jobs.

 

Important Safety Guidelines for Lithium Battery Usage

We ask you to treat our cells with respect. Check every unit before use. If it is dented, swollen, or leaking, do not charge or use it. Keep the terminals clear of metal to avoid a short. Charge only with an approved device and stay nearby while it tops up. Let the pack cool to room temperature between cycles. Store it at 30-50% charge in a clean, dry spot between 10°C and 25°C, away from heat, water, and flames. Follow the basics, and your high power lithium battery stays safe. 

Safety sits at the heart of our work. We run routine abuse tests and maintain a system that satisfies ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and IATF 16949:2016. Not only that, but we have also earned AS9100:D for aerospace-grade production. Every design clears rigorous international safety standards checks before we ship. A Plan–Do–Check–Act loop plus outside audits keep the bar high. These certifications show we do more than promise safety—we certify it.
