Product overview
Shenzhen Grepow Battery Co., Ltd.’s Tattu 4.0 18S 35Ah 68.4V is a high-voltage intelligent battery for heavy-lift professional UAVs with approximately 70–100 kg maximum takeoff weight. Applications include agricultural crop protection, logistics, surveying and mapping, inspection, and electric vertical takeoff and landing aircraft. Its 18S1P cell configuration provides 35000mAh nominal capacity and 2394 Wh of energy. Integration requires assessment of the aircraft’s motor system, total power consumption, payload weight, battery-compartment dimensions and endurance target.
The battery combines a plug-and-play installation design with an integrated BMS, MOS management switch and air cooling. Electrical and data connections use an ACES 59615-0149D001 discharge connector and DroneCAN communication. The high-power connector has a 500A rating and supports mainstream 270A UAV interfaces; the battery’s maximum continuous discharge current is 270A, with 350A peak discharge limited to three seconds. Built-in management functions include overcurrent and undervoltage protection, automatic balancing, charge calculation, operating-data recording and remote control.
Bluetooth access through a mobile app provides battery-status and state-of-health information, while charging reminders and abnormal-state alarms support battery management. The pack supports charging at up to 5C and can exceed 1000 cycles. Paired with the recommended TA7200 PRO 7200W dual-channel intelligent charger, it supports approximately nine-minute fast charging. Actual charging time depends on charging settings, ambient temperature, remaining battery charge and power-supply conditions. The recommended charger accommodates 12S–18S intelligent batteries.
