Product overview
Shenzhen Grepow Battery Co., Ltd.’s Tattu pro is a smart UAV battery intended principally for medium and large agricultural crop-protection aircraft. The configuration combines 22000 mAh capacity with a 44.4 V nominal voltage and a 12S1P cell arrangement. Its continuous discharge rating is 25C, with a maximum momentary rating of 50C, and it supports 3C fast charging. Aircraft selection must account for both continuous and peak current demand.
The battery occupies a 117 × 174 × 238 mm envelope and weighs 6300 g with a ±20 g tolerance. Its discharge wiring uses an 8# specification and a 230 mm lead with a ±2 mm tolerance; charging and discharging ports are provided. Connector designations differ: AS150U-F is identified as the discharge plug, while AS150-F appears in the connector specification. Integration therefore requires matching the connector alongside battery-bay dimensions, retention arrangements, current requirements, and permitted aircraft weight.
Battery management includes charge calculation, automatic balancing, data collection and transmission, charging reminders, and abnormal-state alarms. Low-temperature self-heating works alongside health self-checks, fault recording, historical information storage, and charging and communication protection. Water, dust, and fire protection functions are also included. Before cold-weather operation, battery temperature, remaining charge, and health still require checking. Compatible charging options include the TA3200, TA7200, TA9000, and TA9000 PRO; charger selection depends on charging power, site power supply, channel count, and battery turnaround needs.
