We’ve been buying from VATS Battery for over a year now, and they never disappoint. This 10500 3.7V cylindrical lipo is a little powerhouse for our wearable tech line. Zero memory effect, lightweight (around 8g as listed), and the price-to-performance ratio at around $1.20 is unbeatable for Grade A cells. Standard T/T payment was smooth, and lead times are always predictable. Highly recommended for any tech startup or established manufacturer.

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.

Super expérience avec ce fournisseur. J'ai d'abord demandé des échantillons gratuits pour tester la tenue des 500 cycles sur nos mini-drones, et l'équipe commerciale a été ultra réactive. Les tests sont excellents, la tension de 3.7V reste bien stable. Le service client parle un anglais parfait et suit le dossier de près. C'est un vrai plaisir de travailler avec des pros.
