Product overview
The Grepow Tattu 3.0 14S 22000mAh 51.8V 25C is a smart lithium-polymer battery for professional UAV power integration. It is designed for aircraft with maximum takeoff weights of 25kg to 85kg and agricultural drones with capacities of 10L to 50L. Applications include spraying, surveying, photography, inspection, cargo delivery and eVTOL aircraft. High-energy-density cells work with an advanced battery management system offering automatic balancing, power calculation, data collection and transmission, charging reminders and abnormal-status alarms.
The pack has a 14S1P, 14-cell configuration and occupies 279mm length × 236mm width × 91mm height, with a net weight of 8800g ±20g. Its aluminum housing provides heat dissipation, alongside sealed waterproof construction and a drawer-slide design for plug-and-play installation. Features include a smart external anti-spark device, portable smart checker and LED indicator. Electrical integration uses a Molex-43045-1600 charge connector and a separate Molex-46562-2657 discharge connector.
The battery has a minimum capacity of 22000mAh, a 25C discharge rating and a maximum burst discharge rating of 50C. Maximum continuous current is 150A. The 14S 22000mAh battery supports 3C fast charging; maximum 5C fast charging is specified with TA3000, T3200, TA3200W or TA9000W PRO chargers. Its lifespan can exceed 600 cycles. These charging figures retain their distinct configurations, with the maximum 5C capability tied to the named chargers.
