Product Description

103080 3000mAh 3.7V Lithium Polymer Battery

103080 3000mAh 3.7V Lithium Polymer Battery 4.2V Max Cutoff Custom JST Molex Connector 500 Cycles LiPo Cell for Power Bank Medical GPS Beauty Toys

Core Specification & Performance Features

This 103080 lithium polymer battery is a standardized soft-pack LiPo cell with precise dimensional control, measuring 10±0.2mm (thickness) * 30±0.5mm (width) * 80±3mm (length). It delivers a nominal capacity of 3000mAh at a standard 3.7V nominal voltage, with a safe 4.2V maximum charging cutoff voltage to avoid overcharging damage.

The cell supports stable standard discharge rates between 0.2C and 0.5C, with a peak sustainable discharge current of 1C, balancing steady power output and cell lifespan. It achieves up to 500 full charge-discharge cycles, far exceeding cheap low-grade polymer batteries on market.

Customization is fully supported: buyers can alter cell thickness, capacity, voltage, and wiring terminals to match unique device design demands. Two mainstream connector options—JST and Molex—are selectable to fit diverse PCB and wiring assembly requirements, eliminating extra adapter costs for manufacturers.

Wide Application Compatibility

This 103080 LiPo battery is engineered as a universal power source for multiple consumer and industrial segments. It works seamlessly with portable digital electronics, handheld medical facilities, GPS tracking locators, compact power banks, skincare beauty equipment, and electronic toys.

Its slim rectangular form factor saves internal device space for designers, while consistent power delivery ensures stable operation of precision medical sensors and GPS positioning modules. For beauty devices like facial massage tools and handheld beauty wands, the steady 0.2C-0.5C discharge avoids voltage drops during high-load working modes.

Toy manufacturers benefit from its long cycle life to reduce product after-sales battery replacement complaints, and power bank brands can customize capacity to match lightweight portable charging solutions.

Reliable Safety & Certified Quality

Manufactured by VATS BATTERY, a professional Chinese lithium battery factory, this cell holds ISO9001 quality management and ISO14001 environmental management certifications, complying with global industrial production standards. Every unit undergoes strict internal short-circuit, overcharge, and over-discharge testing before shipment.

Packaging adopts industrial cartons that fully meet international air and ocean shipping safety regulations, passing lithium battery dangerous goods transport checks without extra logistics delays. The factory's standardized production process eliminates inconsistent cell performance, and the built-in polymer electrolyte reduces leakage risk compared to liquid lithium-ion cells, lowering fire and swelling hazards during long-term daily use.

Ich war anfangs echt ein bisschen skeptisch, weil man im Netz ja viel zu hören bekommt, wenn es um Li-Polymer-Akkus geht. Aber der originale E66 Akku hier? Junge, Junge... das Teil ist ein Biest! Ich habe die Zelle jetzt seit ein paar Wochen in meinem DIY-Solar-Projekt verbaut und ausgiebig getestet. Was soll ich sagen: Die 66ah sind absolut real, kein Fake-Wert! Die Kapazität ist stabil, die Spannung von 3.7V bleibt auch unter Last super konstant und das Teil wird beim Laden kaum handwarm. Man merkt einfach sofort, dass die Verarbeitungsqualität stimmt und das PCB-Schutzboard ordentlich mitgedacht wurde. Für den Preis kriegt man hier in Deutschland aktuell kaum was Besseres. Versand war auch fix, Verpackung war bombensicher – so muss das laufen! Wer verlässliche Power sucht, kann hier echt bedenkenlos zugreifen. Von mir gibt's eine klare Kaufempfehlung und verdiente 5 Sterne. Daumen hoch!

I’ve been using this 357090 3.7V 2500mAh lipo battery for a few weeks now, and I’m really satisfied with it. It is steady-quality rechargeable lithium polymer batteries that perfectly match the rated voltage and capacity. Output efficiency is great, which helps me save a lot of working time. Build quality feels solid too, no weird noises or faults during daily operation. Shipping was fast and the packaging was protective. For small-scale battery production and copying work, this is absolutely a practical and cost-effective pick. I’d definitely recommend it to fellow business partners and will consider reordering in the future.

I bought these 805050 3.7V 2500mAh lithium polymer batteries to replace the old cells in my Bluetooth speakers, and they work brilliantly. Fit is absolutely perfect, no trimming needed at all. The voltage and capacity are spot on, my speakers now hold charge for much longer than before. Power output is stable, sound quality isn’t affected one bit. They’re well-made and feel really durable. Delivery arrived quickly, items were well packed with no damage. Great value for money compared to local stores. I’ve been using them daily for weeks with zero issues. Would absolutely recommend these batteries to anyone needing replacements for wireless speakers. I’ll be coming back to buy more soon!
