Product Description
11500 3.7V 500mAh Cylindrical Lithium Polymer Battery Cell for Portable Devices
Product Overview

The 11500 is a cylindrical lithium polymer cell with a nominal capacity of 500mAh and nominal voltage of 3.7V, built in a round format of approximately 11.0 mm diameter × 50.0 mm length.

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.

I’m really impressed with this customized 7.4V 16000mAh 18650 battery pack! It fits all my power tools and small electronics perfectly, exactly as I hoped. The large capacity is a total game-changer — I can work for hours on end without constantly recharging. Charging works smoothly, and the power output stays stable the whole time. No sudden power cuts or overheating issues at all. Build quality feels solid and durable, clearly well-made. I also love that it’s customizable to match different devices. Shipping was fast and the item arrived well-packaged. For this price, you simply can’t beat the performance and capacity. Highly recommend it to anyone needing a long-lasting, reliable battery pack for tools or electronics. Will definitely buy again!
