Product Overview

The 401020-5C is a 3.7V 50mAh lithium-polymer pouch cell manufactured by VATS Battery, an ISO9001-certified lithium battery maker based in Guangdong, China. Built on a compact customizable footprint, it combines a stable 3.7V nominal voltage with a true 50mAh 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 before shipment, which keeps batch-to-batch consistency high and makes the 401020-5C a dependable drop-in power source for OEM and ODM programmes. Because the chemistry, dimensions and protection circuit can all be customized, engineers can either select this standard model or ask us to develop a bespoke cell around a specific power, footprint and cost target.

Key Features

True Rated Capacity: Delivers a genuine 50mAh at 3.7V, verified by capacity, voltage and internal-resistance testing on every production lot.
Stable Output: A flat discharge curve holds close to 3.7V, protecting sensitive circuits and extending usable runtime.
Long Cycle Life: Rated for more than 500 charge–discharge cycles with excellent capacity retention.
Certified Safety: Compliant with IEC62133 / UL / CE / CB / KC / UN38.3 / MSDS, with built-in protection against over-charge, over-discharge, over-current and short circuit.
Flexible Customization: Size, capacity, voltage, connector, wire length and PCM can be tailored to your design; OEM and ODM are both welcome.
Ready to Integrate: Supplied with JST / Molex (optional) so the cell can drop straight into your assembly line.

Applications

Thanks to its slim, lightweight build and stable 3.7V output, the 401020-5C fits a wide range of applications including:

Digital products
Bluetooth devices
GPS trackers
Power banks
Portable electronics
Bluetooth speakers and headsets
Fitness wearables and smart watches
Medical and healthcare instruments
Beauty and personal-care devices
IoT sensors
LED lighting
Toys

Its customizable connector and protection circuit simplify integration, reducing assembly time and supporting both prototyping and high-volume mass production.

Packaging & Quality Assurance

Every 401020-5C is packed in industrial cartons with anti-static trays and shock-absorbing material that meet international air and sea shipping standards, protecting the cells throughout transport. VATS Battery produces over 300,000 cells per day and exports to more than one hundred countries, offering a seven to twenty day lead time, free samples for evaluation, and a twelve-month warranty. If you need datasheets, samples or a custom specification, contact our sales team and we will match the right cell to your project and support you from prototype through mass production.

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.

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.
