The Tattu 4.0 is a newly upgraded smart drone battery featuring an optimized plug-and-play design, high energy density cells, and an advanced BMS. специально engineered for heavy-payload drones, particularly 30–50L agricultural drones. It supports up to 270A continuous discharge and 5C fast charging when used with the TA9000Pro Charger.
It integrates a high-precision BMS with built-in Bluetooth and delivers comprehensive safety features, including Drone CAN protocol access, Bluetooth connectivity, SOC display, fault self-diagnosis, self-balancing, smart storage, log recording, cycle statistics, software upgrades, and automatic charging current adjustment with protection functions—ensuring safe and reliable flight operations. The built-in power switch also prevents sparking by allowing the battery to be turned off before connecting to any device.
The internal structure has been fully upgraded to enhance heat dissipation for more efficient cooling performance. The Tattu 4.0 eliminates the need for USB communication by integrating Bluetooth directly into the BMS, enabling real-time battery monitoring and seamless human–battery interaction. The handle design has also been refined for improved ergonomics and aesthetics. Additionally, the enhanced structural design minimizes the risk of corrosion-induced short circuits caused by moisture or liquid exposure, further improving safety and reliability.
By connecting to the Tattu Bluetooth App, users can conveniently upgrade battery firmware, monitor real-time battery data, and access historical operation logs.
