The DOGCOM 6S2P 10000mAh Li-Ion battery is a high-power endurance pack built with Molicel INR21700-P50B cells. It is designed for long flight times and efficient cruising, while the P50B's low internal resistance gives it noticeably more current headroom than typical endurance Li-Ion packs.

It is well suited for large 7" to 10" long-range platforms such as the Helion 10, Chimera7 or CineLR7 – depending on total weight, motors, props, payload, current draw and flying style.

Important: This is a Li-Ion endurance pack, not a high-discharge freestyle LiPo. It is not intended for racing, aggressive freestyle or repeated full-throttle punches.

Key Benefits

• 10000mAh capacity for long endurance and exploration flights
• Molicel INR21700-P50B high-power 21700 cells
• 6S2P configuration for higher capacity and better current sharing
• 10C continuous rating from the manufacturer (approx. 100A)
• Higher energy density than typical high-discharge LiPo packs
• Smooth power delivery for cruising, cinematic flying, mapping, inspection and exploration
• XT60 or XT90 main connector, JST-XHR balance plug
• Compact 43 × 64 × 145mm, approx. 896g
• Estimated flight time around 20+ minutes in suitable setups – actual flight time depends on aircraft, payload, weather and flying style

Li-Ion Battery Behaviour

Li-Ion packs offer higher energy density and better cruising efficiency, but lower high-current capability and more voltage sag under load than LiPo packs. The Molicel P50B is one of the stronger 21700 cells for high current draw, but the pack can still feel softer than a LiPo during hard acceleration or high-throttle manoeuvres. This is normal Li-Ion behaviour.

For best results, use smooth throttle control, efficient props, suitable motors and an endurance-oriented setup.

Betaflight and OSD Voltage Warning Note

Default LiPo low-voltage warnings may not suit Li-Ion packs and should be adjusted by an experienced user. Li-Ion voltage curves differ from LiPo, and voltage sag increases at high current, in cold weather and towards the end of a flight.

Monitor per-cell voltage, consumed mAh, voltage sag under load and resting voltage after landing.

Cell Temperature Guidance

• Charging ambient: 0°C to 45°C
• Discharging ambient: –20°C to 60°C
• Do not charge below 0°C.
• Do not charge or use the pack if it is very hot, swollen, damaged or behaving abnormally.
• Cold cells show more voltage sag and less usable capacity; heat accelerates aging and can be unsafe.

Charging Guidelines

• Use a balance charger that supports Li-Ion, set to Li-Ion / lithium-ion balance mode.
• Max charge voltage: 4.20V per cell / 25.2V total.
• Recommended charge rate: 1C or lower – up to 10A for this pack.
• Molicel P50B reference: 5A standard charge per cell (approx. 10A for this 2P pack). The higher maximum charge current in the cell datasheet is temperature-limited and not a recommendation for this pack.
• Charge at 10A or lower unless the pack label or manufacturer explicitly allows more.
• Do not charge unattended, near flammable materials, below 0°C, or if the pack is damaged, swollen, overheated, crashed, over-discharged, shorted, wet or otherwise suspicious.
• Stop charging immediately if the pack becomes hot, swells, smells unusual, shows cell imbalance or behaves abnormally.

Discharge and Landing Guidelines

• Designed for efficient cruising, not for extreme current draw.
• Target resting voltage after landing: approx. 2.9–3.1V per cell.
• 2.5V per cell is the absolute cut-off specification, not a normal landing target.
• Loaded voltage during flight can be lower than resting voltage.
• Repeated deep discharges reduce cycle life and increase the risk of cell imbalance.
• If voltage sag is excessive, land safely and review your setup (aircraft weight, payload, props, connector and flying style).

Storage Guidelines

• Storage voltage: 3.7–3.85V per cell.
• Avoid storing the pack fully charged or fully empty for long periods.
• Disconnect from aircraft and chargers after use.
• Store cool and dry, ideally at 15°C–25°C, away from heat, direct sunlight, freezing temperatures, moisture and mechanical damage.
• Use a fire-resistant or LiPo-safe bag or container.
• Inspect the pack regularly. Stop using it and dispose of it properly if it shows swelling, leakage, odour, corrosion, damage or cell imbalance.

Safety Disclaimer

Lithium batteries can cause fire, explosion, injury or property damage if they are charged incorrectly, over-discharged, short-circuited, overheated, damaged, punctured or disassembled. Always use a compatible charger and follow the specifications and the information on the battery label.

The user is responsible for choosing a suitable battery for the application and for operating it within its voltage, current, temperature and handling limits. Do not use the battery if it has been crashed, punctured, swollen, overheated, over-discharged, short-circuited, wet or physically damaged.

Shipping Note

This battery exceeds 100Wh and is subject to IATA dangerous goods regulations. Express air shipping is therefore not available – express orders are switched to compliant ground shipping before dispatch.
