About Tattu
Since 2012, Tattu has been a premium brand of battery manufacturer Grepow, specializing in complete energy systems for drones: from proprietary lithium-polymer cells and battery packs with BMS integration to smart chargers and app-based fleet management. The vertically integrated manufacturing covers in-house cell chemistry (LiPo, LiHV at 4.35–4.45 V, semi-solid-state cells with up to 380 Wh/kg), pack assembly, and custom energy system development. Cell materials with ceramic-coated separators and stable electrolyte additives are designed to ensure safety and cycle life even at high discharge rates (up to 160C). Customers include industries such as agriculture, surveying, inspection, delivery drones, aerial photography, media and education. With service and warehousing centers in California (USA) and in Korschenbroich (North Rhine-Westphalia, Germany), Tattu supplies customers in over 100 countries; more than 200,000 m² of production space is available.
