Manufactured in Europe for Professional Applications

The finished battery pack is manufactured in Europe using Samsung INR21700-50S lithium-ion cells.

It is designed for professional and endurance-focused UAV applications, including industrial inspection, mapping, research, testing, fleet operation, system integration, long-range operation, and other specialized applications.

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

The use of established Samsung 21700 cells also provides a clearly defined cell platform for professional system integration.

Li-Ion Battery Behaviour

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

Compared with high-discharge LiPo packs, Li-Ion batteries generally provide higher energy density and improved endurance but can show greater voltage sag under high load.

This battery is designed primarily for efficient long-range operation, professional UAV use, mapping, inspection, research, testing, and endurance applications.

It may feel softer than a high-discharge LiPo during hard acceleration or high-throttle manoeuvres. This is normal Li-Ion behaviour and does not automatically indicate a defective battery.

For best results, use an aircraft and power system designed for endurance operation and ensure that motors, propellers, wiring, connectors, and expected current draw are suitable for the battery.

Betaflight and OSD Voltage Warning Note

Many Betaflight and FPV OSD low-voltage warning configurations are based on typical LiPo behaviour.

Li-Ion batteries have a different discharge curve and can show increased voltage sag under load, particularly at high current, low temperature, or near the end of the available capacity.

Voltage warning settings may therefore need to be adjusted by an experienced user.

Always monitor:

• Individual cell voltage

• Pack voltage

• Consumed mAh

• Voltage sag under load

• Battery temperature

• Resting voltage after landing

Do not rely exclusively on default LiPo warning settings when operating a Li-Ion battery.

Discharge and Temperature Guidance

• Continuous discharge current: 50A

• Continuous discharge current below 80°C: up to 90A

• The 90A rating applies only while the battery remains below the specified 80°C temperature limit.

• Minimum cell voltage: 2.5V per cell.

• The 2.5V value is the specified minimum cell voltage and should not be treated as a routine target for every flight.

• Avoid repeatedly operating the battery at its maximum current, temperature, or minimum-voltage limits.

• High current draw increases voltage sag and heat generation.

• Cold Li-Ion cells may show stronger voltage sag and reduced usable capacity.

• Excessive temperature accelerates battery ageing and can create unsafe operating conditions.

• If voltage sag or battery temperature becomes excessive, reduce load and land safely.

• Always ensure that the aircraft, wiring, connectors, ESCs, and power system are suitable for the expected current.

Charging Guidelines

• Always use a compatible balance charger suitable for a 6S lithium-ion battery with a maximum charge voltage of 4.20V per cell.

• Maximum pack voltage: 25.2V / 4.20V per cell.

• Recommended charging current: 5A.

• Maximum pack charging current: 12A.

• For normal operation and improved battery longevity, use the recommended 5A charging current.

• Do not exceed 12A charging current.

• Do not charge above 25.2V / 4.20V per cell.

• Always balance charge the battery.

• Do not charge unattended.

• Do not charge near flammable materials.

• Do not charge the battery when it is excessively cold or hot.

• Do not charge a damaged, swollen, overheated, crashed, deeply discharged, shorted, wet, or otherwise suspicious battery.

• Stop charging immediately if the battery becomes unusually hot, swollen, develops an unusual smell, shows abnormal cell imbalance, or otherwise behaves abnormally.

Discharge and Landing Guidelines

• This battery is primarily designed for efficient long-range and endurance operation rather than repeated extreme-current manoeuvres.

• Continuous discharge current: 50A.

• Continuous discharge below 80°C: up to 90A.

• Minimum cell voltage: 2.5V per cell.

• Do not intentionally operate the battery continuously at its minimum cell-voltage limit.

• Maintain an appropriate safety reserve for the aircraft and operating conditions.

• Voltage under load can be lower than the resting voltage measured after landing.

• Repeated deep discharge can reduce cycle life and increase the risk of cell imbalance or damage.

• If voltage sag or temperature becomes excessive, reduce load and land safely.

• Ensure that the battery is suitable for the aircraft, payload, motors, propellers, connector, and intended operating profile.

Storage Guidelines

• Store the battery partially charged rather than fully charged or deeply discharged for extended periods.

• Disconnect the battery from the aircraft, charger, or other device after use.

• Store in a cool, dry, well-ventilated location.

• Avoid high temperatures, direct sunlight, freezing conditions, moisture, and physical damage.

• Keep away from flammable materials.

• Use an appropriate fire-resistant battery storage solution.

• Inspect the battery periodically during long-term storage.

If swelling, leakage, abnormal smell, corrosion, physical damage, abnormal heating, or unusual cell imbalance is detected, stop using the battery immediately and dispose of it according to applicable local battery-disposal regulations.

Transport Information

The battery model is UN38.3 tested and MSDS / SDS documentation is available.

Due to its energy content of approximately 216Wh, dangerous-goods transport, packaging, labelling, carrier, and destination-specific restrictions may apply.

UN38.3 testing confirms that the battery model has undergone the applicable transport testing. It does not remove other applicable requirements for the transport of lithium batteries.

Lithium batteries must be handled with care. Incorrect charging, overcharging, deep discharge, short-circuiting, overheating, physical damage, puncturing, disassembling, or use outside the specified operating limits can cause fire, explosion, injury, or property damage.

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

Before use, ensure that the battery is suitable for the voltage, current, weight, connector, and operating requirements of the intended aircraft or system.

Do not use the battery if it has been crashed, punctured, swollen, overheated, deeply discharged, shorted, exposed to water, or otherwise physically damaged.

Stop using the battery immediately if abnormal heat, swelling, smell, leakage, cell imbalance, or other unusual behaviour is observed.

Always comply with applicable safety, storage, transport, and disposal requirements.
