Product overview
Grepow’s Tattu 4.0 30000mAh 35C 53.2V 14S1P is a high-voltage intelligent battery for heavy UAVs, including agricultural, logistics, surveying and inspection platforms. Its intended aircraft class is approximately 70–100 kg maximum takeoff weight. The pack combines an all-aluminum-alloy enclosure, convection cooling windows and dedicated airflow passages with IP65 protection. A rigid plug-in structure and fitted connector support battery replacement. Integration requires assessment of the aircraft’s voltage platform, total power consumption, mission payload and battery compartment structure.
The battery incorporates a BMS and MOS switch for electrical and temperature protection, intelligent charging, remote control and abnormal-state alarms. Automatic storage and cell balancing support maintenance, while a Bluetooth-connected mobile application provides battery status monitoring. Maximum continuous discharge is 270A, with an instantaneous peak of up to 360A; aircraft demand must remain within permitted limits. Fast charging supports up to 150A at 5C within 20–55°C. Actual charging speed depends on charger power, supply conditions, battery temperature and remaining charge.
