Understanding the High-Temperature Challenge in Drone Operations
Drones deployed in hot climates, industrial inspection sites, or equipment enclosures often face a common operational constraint: standard lithium battery cells are simply not engineered to tolerate sustained high-temperature exposure. Conventional battery packs typically carry an applicable temperature range that tops out around 60℃. Once ambient or internal operating temperatures exceed this threshold, batteries are prone to swelling, capacity degradation, and in severe cases, safety incidents. For operators running drones in 70℃ environments — such as certain terminal or industrial high-temperature operation sites — this limitation directly affects flight reliability and overall mission efficiency.
Shenzhen Jentc Technology Co., Ltd. (brand names Jentc and Rechane), a company that has focused on high-rate battery customization since its establishment in 2011, has built its product development around solving exactly this type of pain point. The company’s stated business philosophy — "industry development as the guide, application technology as the cornerstone, and value enhancement as the mission" — reflects an approach centered on translating specific operational pain points into engineered battery solutions rather than offering generic, off-the-shelf products.
Jentc Technology’s Approach to High-Temperature Drone Battery Design
Material-Level Innovation
According to information provided by the company, its high-temperature drone battery development process centers on cell-level material customization. Rather than relying on standard electrolyte and electrode formulations, Jentc’s technical process for high-temperature applications uses a unique high-temperature electrolyte, along with specific treatments applied to the corresponding pole pieces. In addition, the company states that it modifies other high-temperature materials and technological measures specifically to prevent high-temperature bulging — a common failure mode when standard lithium batteries are pushed beyond their rated thermal range.
This mirrors the broader customization scope the company applies across its high-rate battery product line, which is defined for high-temperature performance below 80℃. This range indicates that Jentc’s engineering process is not limited to a single case but is structured as a repeatable customization capability that can be adjusted according to a customer’s specific thermal operating environment.
BMS-Level Temperature Protection
Battery performance in extreme conditions is not determined by the cell alone. Jentc’s product matrix also includes customized BMS (Battery Management System) development, and the company’s BMS customization service explicitly lists temperature protection among its basic requirements, alongside overcharge, over-discharge, over-current, and short-circuit protection. The BMS also supports data collection functions — including the ability to monitor battery voltage, current, and temperature — which allows operators to track thermal conditions during flight or operation in real time. For companies operating in high-temperature terminal environments, this combination of cell-level thermal formulation and BMS-level temperature monitoring is presented by the company as a coordinated system rather than two separate offerings.
Proven Field Performance: The 70°C Case Study
The most direct evidence of Jentc’s high-temperature drone battery capability comes from a documented 2026 project case involving a high-temperature drone application. The customer’s original battery was a 22.2V 10Ah cylindrical high-rate lithium battery, with an applicable temperature range of -20℃ to 60℃ — insufficient for the customer’s actual operating environment, which reached 70℃.
To address this scenario pain point, Jentc developed a customized 22.2V 10AH battery specifically rated for 70℃ high-temperature drone operation. The technical process, as described by the company, involved use of a unique high-temperature electrolyte, targeted treatment of the corresponding pole pieces, and modification of other high-temperature materials and technological measures to prevent bulging under sustained heat exposure.
The documented result of this project was that the customized battery met the operational needs of the 70℃ high-temperature environment and improved the efficiency of terminal high-temperature operations. This case illustrates a direct, measurable link between the identified pain point (an operating environment exceeding the original battery’s 60℃ ceiling) and the engineered outcome (a purpose-built 70℃-rated battery), without requiring the customer to compromise on the 22.2V 10AH specification already integrated into their drone system.
Customization Scope and Industry Adaptation
Beyond this individual case, Jentc’s high-rate battery product line — which includes high-temperature lithium batteries as a distinct category — is defined by a broader set of customization parameters. These include an energy density of up to 420Wh/kg, voltage up to 400V, discharge rate up to 180C, cell capacity up to 90AH, fast charging up to 5C, low-temperature operation down to -70℃, and high-temperature operation below 80℃, supported by a complete set of lithium battery BMS software and hardware solutions.
This customization range is positioned by the company to serve a range of industries beyond drones alone, including robots, robot dogs, laser equipment, portable equipment, and other equipment used in high-heat or high-source operating scenarios. For drone-specific deployments, the company lists industry adaptation across agricultural plant protection, large-load drones, power and photovoltaic inspection, crossing drones, pipeline inspection drones, logistics drones, cleaning drones, and formation drones — many of which can involve exposure to elevated ambient or equipment-generated heat depending on deployment conditions.
A Track Record of Technical Development
Jentc’s technical accumulation timeline, as documented by the company, spans multiple generations of battery and BMS innovation, including the 2015 introduction of a 4.35V high-voltage drone battery, a 2019 active battery balancing system, a 2021 4.4V ultra-high-voltage large-capacity drone battery, and a 2024 -30℃ to 10C low-temperature rate discharge drone battery, among other developments. While these milestones primarily concern voltage and low-temperature performance rather than high-temperature engineering specifically, they reflect a consistent pattern: each product introduction responds to a defined operational pain point identified in real customer scenarios, a pattern that is repeated in the company’s 70℃ high-temperature drone battery case.
Why the High-Temperature Case Matters for Operators
For businesses evaluating drone battery suppliers for high-temperature terminal operations, the documented 70℃ case offers a concrete reference point rather than a general claim. The scenario pain point (operating environment exceeding the customer’s original 60℃-rated battery), the specific technical measures applied (high-temperature electrolyte, pole piece treatment, material modification against bulging), and the documented outcome (meeting the 70℃ requirement and improving terminal operating efficiency) together demonstrate a traceable engineering process. Combined with the company’s broader high-temperature customization scope of below 80℃ and its integrated BMS temperature protection capability, this case positions Jentc’s high-temperature drone battery development as a specialized, scenario-driven response to a well-defined industry pain point rather than a repackaged standard product.
