Product overview
Grepow’s Tattu 3.0 14S 19000mAh 51.8V 25C Lipo Smart Drone Battery is a power component for commercial UAV integration. Its intended aircraft range includes drones with 25kg to 85kg maximum takeoff weight and agricultural drones in the 10L to 50L class. Applications extend to surveying, aerial photography, delivery, inspection and eVTOL aircraft. The product is a smart battery, with high energy density cells and an advanced battery management system, rather than a complete flight platform or airframe kit.
The battery uses a 14S1P arrangement of 14 cells at 51.8V, with a minimum capacity of 19000mAh. Its enclosure measures 279mm long, 236mm wide and 91mm high, and net weight is 7900g with a ±20g tolerance. Physical integration features include drawer slides, plug-and-play installation and an aluminum housing for heat dissipation. The design also incorporates sealed waterproof construction, an external smart anti-spark device, a portable smart checker and an LED indicator. Charging and discharge connections use Molex-43045-1600 and Molex-46562-2657 plugs respectively.
Electrical specifications distinguish a 25C discharge rate, a 50C maximum burst discharge rate and a maximum continuous current of 150A. Charging support includes 3C fast charging, with a separate maximum 5C capability tied to TA3000, T3200, TA3200W and TA9000W PRO chargers. Battery lifespan can exceed 600 cycles. Management functions include automatic balancing, power calculation, data collection and transmission, charging and safety reminders, and abnormal-status alarms. These functions support battery monitoring within the intended drone installation.
