Modern miniature electronics require battery solutions that can deliver reliable performance without occupying valuable internal space. The Yideng 1054 pouch coin LiPo battery is developed specifically for compact devices where thickness, weight, and flexible installation are critical design factors.
With a 3.85V operating voltage and 45mAh capacity, this mini rechargeable button cell adopts a soft pouch structure measuring only 10.0 × 5.4mm, allowing engineers to integrate power sources into ultra-small product designs.
Compared with traditional rigid coin-type batteries, the pouch LiPo structure provides greater flexibility in customization and assembly. Manufacturers can optimize battery placement, connection methods, and protection solutions according to different product architectures.
The 1054 Pouch Coin Lipo Battery Mini Rechargeable Button Cell is especially suitable for:
- Wireless earphones requiring compact internal layouts
- Smart sensors needing lightweight power sources
- Smart pens and miniature electronic devices
- IoT products with strict space limitations
Yideng supports complete customization services, including PCM configuration, lead wire selection, connector adaptation, and battery packaging solutions, helping customers move efficiently from prototype development to volume production.
