Product overview
Shenzhen Grepow Battery Co., Ltd.’s Tattu 4.0 18S 30Ah 68.4V is a high-voltage smart lithium battery for heavy-lift UAVs, including agricultural, logistics, surveying and inspection aircraft and some eVTOL platforms. Its 18S1P pack provides 30000mAh nominal capacity and 2052 Wh of energy. The physical assembly combines an aluminum-alloy housing with cooling-air ducts, sealed waterproof construction and a drawer-slide installation structure. Integrated equipment includes an intelligent fire-protection device, a portable smart detector and LED status indicators, alongside the internal BMS and MOS management module.
Installation requires an aircraft supporting an 18S, 68.4V electrical platform, with room for an approximately 330 × 267 × 120 mm battery weighing 14300±350g. Connector selection is ACES 59615-0149D001 or Molex, with DroneCAN communication. The battery supports charging up to 5C, while its continuous discharge limit is 270A and its 360A peak is limited to three seconds. Bluetooth app access provides battery-status and state-of-health monitoring. Intended aircraft have approximately 70–100 kg maximum takeoff weight; suitability also depends on aircraft power demand, mission payload and peak current.
