LPR432421 155mAh 3.7V 0.57Wh Round LiPo Battery With Connector Molex 78172-0002

Space-Saving Geometric Power, Industrial and consumer electronic design trends are shifting toward organic, curved, and circular form factors. Traditional rectangular batteries often leave significant wasted space inside cylindrical or circular casings. As a pioneering LiPol Battery Manufacturer, we engineer specialized shapes to maximize internal volume. The LPR432421 represents a high-efficiency Round LiPo Battery designed to solve these exact geometric hardware constraints. Unique Round LiPo Battery Designs Are Available Only From LiPol Battery Manufacturer.

Maximizing Circular Internal Volume, The LPR432421 is an optimized, circular Lithium Polymer Battery built for ultra-compact integration. It features a ultra-low 4.3mm Thickness LiPo Battery profile, a 24mm Width LiPo Battery layout, and a 22mm Length LiPo Battery span—ultimately shaping a precise Diameter 24mm footprint.

Operating at a nominal 3.7V LiPo Battery standard, this cell delivers a capacity of 155mAh LiPo Battery, translating to 0.57Wh LiPo Battery of reliable energy. To ensure effortless electrical integration, this Li-Polymer Battery comes pre-assembled with a genuine, low-profile Molex 78172-0002 connector, making it an excellent plug-and-play solution for tight miniature assemblies. Round LiPo Battery Solutions Save Space For Compact Device Design, empowering engineers to build sleeker, smaller products without sacrificing runtime.

High-Standard Reliability & Global Compliance
Whether your engineering documentation classifies it as a LiPolymer Battery or a LiPol Battery, every single circular cell is manufactured under strict quality controls. The LPR432421 includes a micro-scale Protection Circuit Module (PCM) embedded within its structure to protect against over-charging, short circuits, and over-discharging. To support global shipping and commercial distribution, full MSDS (Material Safety Data Sheet) compliance documentation accompanies every batch, guaranteeing smooth air and sea logistics.
