Product Overview The 702025 is a 3.7V 220mAh lithium-polymer pouch cell manufactured by VATS Battery, an ISO9001-certified lithium battery maker based in Guangdong, China. Built on a compact 4.7×20×25mm (T×W×L) footprint, it combines a stable 3.7V nominal voltage with a true 220mAh capacity, so portable devices run longer on a single charge without adding bulk. Each cell is produced on automated lines and individually screened for capacity, voltage and internal resistance
Honestly, it’s a solid 10/15! Finding a reliable 10500 cell with a true 10C discharge rate for our custom power tool prototypes was a nightmare until we found VATS. The continuous discharge is super steady, and the capacity is exactly as advertised. What blew me away was their OEM service—we needed custom wiring and specific connectors, and their engineering team nailed it on the first try. If you're looking for custom high-drain lipo packs, these guys are the real deal.
Spot on service from start to finish. I was a bit skeptical about ordering overseas because we needed these 400mAh batteries urgently for a client's smart pen project. But blimey, they arrived in just over a week! They were out of stock initially, but the communication was brilliant, and they shipped them out the moment they were ready. The packaging was top-notch too, very secure. Will definitely be placing a bulk order soon.
Qualität wie man sie sich wünscht! Für unsere medizinischen Kleingeräte ist die Sicherheit der Akkus das A&O. VATS hat uns alle nötigen Zertifikate (UL1642, CE, UN38.3) direkt vorgelegt – das zeigt einfach, dass hier ein professioneller Hersteller am Werk ist. Der eingebaute PCB-Schutz funktioniert einwandfrei und die Selbstentladung ist minimal. Absolut stabiler und vertrauenswürdiger Partner für B2B.
