Battery Characteristics
Intelligent BMS: Utilizing high-precision measurement and protection chips along with advanced intelligent management technology, it provides users with precise power information and highly secure protection management.
Charge/discharge interface design: Charge and discharge do not affect each other, ensuring high safety performance and low failure rate.
IP67 waterproof and dustproof: The casing is sturdy and resilient, capable of effectively resisting impacts. It maintains a stable size and is not prone to deformation. It has a high level of waterproof and dustproof protection, is corrosion-resistant, is less affected by the environment, and provides customers with a wider range of application scenarios.
Engineered for High-Speed Marine Mapping
Surveying unmanned vessels require a delicate balance between massive power output and minimal payload weight. Driven by KRL Power’s advanced lithium technology, this intelligent USV battery pack integrates premium INR21700 cells to deliver a robust 70A continuous discharge and a 100A instantaneous peak. Weighing strictly under 6KG, it utilizes an innovative composite enclosure (ABS + PC + Aluminum Face Panel). This hybrid housing ensures excellent heat dissipation and impact resistance against marine waves, without burdening the surveying vessel’s buoyancy.
Uncompromising Stability Across Extreme Climates
Marine mapping operations cannot pause for unpredictable weather. KRL’s engineering team has optimized this 28.8V 34.3Ah battery to maintain an ultra-low internal resistance of ≤ 60 mΩ. This guarantees maximum energy conversion efficiency and minimal heat generation during extended missions. Designed for global deployment, the battery reliably executes surveying tasks in extreme climates, supporting discharge operations from freezing -20°C up to blistering 60°C environments.
