Product overview
The Grepow Tattu 3.5 Battery Series provides smart batteries for industrial heavy-lifting drones used in agriculture, logistics and other heavy-lift applications. Designed for drones with a maximum take-off weight of 70 to 100 kg, the series uses grade A cells manufactured by Grepow and has a 30Ah capacity. It supports 4C–5C fast charging, with a specified recharge time of 10 minutes from 30% to 95% charge. The TA9000 Pro Charger is the recommended pairing for these fast-charging capabilities.
The integrated battery management system supports real-time monitoring and access to historical data, together with Drone CAN protocol access, state-of-charge indication, fault self-diagnosis and self-balancing. Other functions include smart storage, log storage, cycle statistics, software updates and automatic charging-current adjustment. The Tattu 3.5 requires the drone to have an anti-spark module to prevent sparking during battery connection. This installation requirement distinguishes it from the Tattu 4.0 series, which incorporates a built-in MOSFET and does not require that module.
