120000mAh 3.7V Ultra-High Capacity Drone Battery LiPo Battery Cell for Long-Endurance UAV Systems

When your drone is hovering over a critical inspection site, racing against a delivery deadline, or mapping kilometers of terrain on a single sortie, the last thing you need is a battery that limits your flight time or struggles under high current loads. The OID13119358-120000mAh-3.7V-3C-0112 from Shenzhen Jianheng Technology Co Ltd is engineered for exactly these moments. With a typical capacity of 123.0Ah, a minimum capacity of 120.0Ah, and an average energy density of 421Wh/kg, this ultra-high capacity lithium-ion polymer cell delivers the endurance, power, and reliability that professional UAV and drone platforms demand.

This cell is not just about raw numbers. It is about solving real operational problems: short flight times, voltage sag under heavy throttle, slow recharge cycles, and safety concerns during aggressive missions. Jianheng has combined an aluminum plastic film shell, low internal resistance, and a wide operating temperature range to create a cell that performs when it matters most.

• Ultra-high capacity: Typical 123.0Ah and minimum 120.0Ah, suitable for long-endurance UAV and drone applications.
• Ultra-high discharge current: Maximum continuous discharge current of 2.0C and maximum pulse discharge current of 3.0C/30s.
• Fast charging capability: Maximum continuous charge current of 0.5C.
• High energy density: Average energy density of 421Wh/kg.
• Low internal resistance: ACIR at 1kHz less than or equal to 1.0 milliohm at 40% SOC.
• Wide operating temperature range: Charging 0 degrees C to 45 degrees C and storage -20 degrees C to 45 degrees C.
• Reliable safety performance: Passes external short circuit, over-discharge, crush, overcharge, drop, saltwater immersion, low pressure, and temperature cycling tests without explosion or fire.
• Long cycle life: Greater than or equal to 80% initial capacity after 300 cycles at 25 plus or minus 2 degrees C.

The cell dimensions are measured without scales. The cell thickness is 11.8mm max at 40% SOC and 13.5mm max at 100% SOC for fresh cells. The width is 119.0mm max and the length is 358.0mm max.

Imagine a survey drone that needs to cover 500 hectares in a single flight. With a conventional 20Ah battery, the mission might require multiple battery swaps and hours of downtime. The OID 13119358 cell, with its 123.0Ah typical capacity, can extend flight endurance dramatically. For a platform consuming 100A at cruise, the math is simple: 123Ah divided by 100A gives over 1.2 hours of continuous flight, compared to just 12 minutes with a 20Ah pack. That is the difference between a quick hop and a full-scale mapping operation.

But capacity alone is not enough. When the drone climbs aggressively or fights headwinds, the current draw spikes. The OID 13119358 supports a maximum continuous discharge current of 2.0C (approximately 240A) and a pulse discharge current of 3.0C (approximately 360A) for 30 seconds. This means voltage sag is minimized, and the drone maintains stable power even during demanding maneuvers. The low ACIR of less than or equal to 1.0 milliohm at 1kHz ensures that energy is delivered efficiently, not wasted as heat.

Fast charging is another critical factor. With a maximum continuous charge current of 0.5C, the cell can be recharged at approximately 60A. For a 120Ah pack, this means a full charge in about two hours, reducing turnaround time between missions. The wide charging temperature range, from 0 degrees C to 45 degrees C with derating, allows operation in diverse climates, from cold morning flights to hot desert conditions.

Safety is paramount in aviation. The OID 13119358 has passed a rigorous battery of tests: external short circuit, over-discharge, crush, overcharge, drop, saltwater immersion, low pressure, and temperature cycling. In each case, the cell exhibited no explosion and no fire. This level of safety performance gives integrators and operators confidence that the battery will not become the weakest link in a critical mission.

Consider a delivery drone operator who needs to transport medical supplies to remote areas. Each flight is 45 minutes. With a 123Ah cell, the drone can carry a heavier payload or fly a longer route without recharging. The cycle life of greater than or equal to 80% initial capacity after 300 cycles means the battery can support hundreds of missions before significant degradation. At one mission per day, that is nearly a year of reliable service. The storage performance, with residual capacity greater than or equal to 90% after 30 days at 25 degrees C, ensures that the battery is ready when needed, even after periods of inactivity.

For high-performance drone racing or freestyle, the pulse discharge capability of 3.0C for 30 seconds provides the burst of power needed for rapid acceleration and vertical climbs. The lightweight design, with an average weight of 1080g and an energy density of 421Wh/kg, helps keep the overall drone weight low, improving agility and flight time.
