The 10000mAh 6S2P Molicel P50B Li-Ion Battery – Made in Europe is a professional-grade high-performance endurance pack manufactured in Europe for demanding UAV, industrial, long-range, and professional applications.

Built using premium Molicel INR-21700-P50B high-power Li-Ion cells in a 6S2P configuration, this battery combines a large 10000mAh energy reserve with exceptional current capability, low cell impedance, documented transport compliance, and European battery-pack manufacturing.

The battery model is UN38.3 tested and supplied with MSDS / SDS documentation, making it particularly suitable for professional customers, UAV integrators, industrial operators, research institutions, public-sector organisations, and projects where documentation and European manufacturing are important procurement requirements.

Molicel specifies the P50B at 60A continuous discharge per cell with an 80°C temperature cut-off. In a 2P configuration, this corresponds to a calculated cell-level reference of 120A.

The European battery-pack manufacturer has additionally performed pack-level testing and reports currents of up to 180A while remaining below 80°C under controlled optimal conditions. This represents a conditional maximum test value and is not the recommended normal operating current.

Made in Europe for Professional Applications

This battery pack is manufactured in Europe using Molicel INR-21700-P50B cells.

It is intended for both recreational long-range FPV and professional UAV applications including testing, research, industrial inspection, mapping, system integration, long-range operation, and public-sector projects.

European battery-pack manufacturing can be particularly relevant where procurement policies, supply-chain requirements, project documentation, traceability, or customer specifications require the finished battery pack to be manufactured within Europe.

High-Power Li-Ion Battery Behaviour

Li-Ion batteries behave differently from standard FPV LiPo batteries.

Conventional high-capacity Li-Ion cells usually prioritize endurance over high-current capability. The Molicel P50B is designed as a high-power Li-Ion cell and provides substantially higher current capability with lower voltage sag than typical endurance-focused 21700 cells.

Molicel specifies 60A continuous discharge per cell with an 80°C temperature cut-off, corresponding to 120A across two parallel cells.

The European battery-pack manufacturer additionally reports successful testing of the complete pack at up to 180A while remaining below 80°C under controlled optimal conditions.

The 180A figure should be treated as a conditional maximum test value, not as the recommended continuous operating current. Actual permissible current may be lower depending on connector, wiring, pack construction, cooling, ambient temperature, state of charge, operating duration, and the complete power system.

Betaflight and OSD Voltage Warning Note

Most Betaflight and FPV OSD low-voltage warnings are configured around standard LiPo behaviour.

Li-Ion batteries have a different voltage curve and may show different voltage behaviour under load, especially at high current, in cold weather, or near the end of the available capacity.

Always monitor voltage per cell, consumed mAh, voltage sag under load, battery temperature, and resting voltage after landing. Do not rely only on default LiPo warning settings when using Li-Ion packs.

Charging Guidelines

• Always use a Li-Ion compatible balance charger.
• Maximum charge voltage: 4.20V per cell / 25.2V total
• Recommended routine charging current: 10A or lower
• Maximum pack charging current: 50A
• The 50A value is a maximum specification and not the recommended routine charging current.
• Do not charge above 4.20V per cell.
• Do not charge unattended or near flammable materials.
• Charging below 0°C requires suitable equipment and controlled conditions.
• Never charge a damaged, swollen, overheated, wet, crashed, or otherwise suspicious battery.

For routine operation and long battery life, we recommend charging at 10A or lower.

Discharge and Landing Guidelines

• Continuous discharge rating: 120A
• Conditional maximum test value: up to 180A below 80°C under controlled conditions
• Recommended end-flight voltage: approx. 2.9–3.1V per cell resting
• 2.5V per cell is the absolute cell discharge cut-off, not a normal landing target.
• Voltage under load may temporarily be lower than resting voltage.
• The safe current capability of the complete system depends on the battery pack, wiring, connector, cooling, ESC, motors, aircraft configuration, and operating conditions.
• Avoid repeatedly operating the battery close to its maximum current, temperature, or minimum-voltage limits.
• Stop operation if battery temperature, connector temperature, voltage sag, or other behaviour becomes abnormal.

Storage Guidelines

• Recommended storage voltage: 3.7–3.85V per cell
• Do not store fully charged for long periods.
• Do not store empty or deeply discharged.
• Disconnect the battery after use.
• Store in a cool, dry place, ideally between 15°C and 25°C.
• Protect from heat, sunlight, moisture, freezing temperatures, and physical damage.
• Store in a suitable fire-resistant battery container or bag.

If swelling, leakage, unusual smell, corrosion, physical damage, or abnormal cell imbalance is detected, stop using the battery immediately.

Safety Disclaimer

Lithium batteries must be handled with care. Improper charging, over-discharging, short-circuiting, overheating, physical damage, puncturing, or incorrect use can cause fire, explosion, injury, or property damage.

Only use a compatible lithium-ion balance charger and always follow the charger instructions, battery label, and product specifications.

The 180A value is a conditional maximum established during pack-level testing by the European battery-pack manufacturer under controlled conditions. It is not an official Molicel cell rating or a recommendation for continuous 180A operation.

The user is responsible for selecting a suitable battery and operating the complete system within its electrical, thermal, and mechanical limits.

Do not use batteries that are damaged, swollen, punctured, overheated, over-discharged, shorted, or exposed to water.
