Product overview

Shenzhen Grepow Battery Co., Ltd.’s Tattu 22000mAh 12S 25C is an intelligent battery for medium and large UAVs serving agricultural crop protection, inspection, security and aerial filming. Its 12S1P cell arrangement provides 44.4V and 976.8Wh. The pack weighs 5800g with a ±20g tolerance and measures 235.3mm high, 116mm thick and 172mm wide, with respective tolerances of ±2mm, ±5mm and ±2mm. Electrical integration uses an AS150U connector, 8# wire and a 230mm discharge lead with a ±2mm length tolerance.

Battery management includes automatic balancing, charging reminders, abnormal-state alarms and operating-history access through CAN/SMBUS interfaces and PC software. Procurement and system integration must account for the separate current limits: maximum continuous discharge is 100A, while 150A peak discharge is limited to less than three seconds. Recommended charging temperatures are +10°C to +45°C, and recommended discharge temperatures are +10°C to +60°C. Maximum charging voltage is 4.2V per cell. Recommended landing and emergency landing thresholds are 43.2V and 42.6V respectively; a red level-II warning requires discontinuing battery use.
