Superbe expérience avec ce fabricant pour nos mini appareils connectés. La cellule 10280 de 3.7V s'intègre parfaitement dans nos designs compacts sans ajouter de poids inutile (seulement 6g !). Nous avons opté pour leur service ODM pour adapter la tension de coupure de décharge à 3.0V, et l'équipe technique a été d'une aide précieuse. C'est rassurant de voir qu'ils gèrent aussi bien la sécurité avec les protections contre la surchauffe. Côté logistique, l'expédition vers la France a été rapide et le suivi ultra clair. On sent la puissance d'une vraie usine derrière.

Absolutely blown away by these 152323 lithium polymer batteries! I run a tiny line of mini facial massage tools, and this 37mAh cell fits my device shell perfectly with zero modification. Super stable 3.7V output, no overheating during daily use, and the 500 charge cycles mean my customers don’t have to replace batteries constantly. I reached out to adjust the connector to Molex for my new model, their support team replied within hours and locked in custom specs for my bulk order. They’re the actual factory, no middleman markup—saved me so much cost compared to local US battery suppliers. Stock units shipped in 5 days, packaging was heavy-duty cartons that cleared US customs without any hold-ups. Already reordered twice, 10/10 recommend for compact portable gadgets!
