Core Product Advantages

1. Slim Soft-Pouch Design for Compact Mini Devices
Different from bulky cylindrical 18650 cells, the thin lithium polymer structure maximizes internal space utilization of slim electronics, ideal for mini Bluetooth speakers, pocket fragrance diffusers and tiny portable audio equipment.

2. Consistent Low-Power Stable Discharge
Optimized cell chemistry supports long-duration low-power operation, maintaining steady voltage during continuous audio playback or atomization. It effectively prevents audio stuttering, weak mist output and unexpected power-off of finished products.

3. Multi-Layer Safety Performance for Daily Use
The aluminum composite film shell features excellent anti-leakage and compression resistance. Matched with external BMS protection boards, the battery realizes comprehensive protection against overcharge, over-discharge, over-current and short circuit, removing hidden safety risks for household and portable consumer electronics.

4. True Rated Capacity & Excellent Batch Consistency
All raw cells complete 100% capacity and internal resistance sorting before shipment. The actual capacity strictly matches the labeled 1200mAh without false marking, cutting down after-sales issues caused by insufficient endurance of your finished goods.

5. Flexible Customization for B2B Partners
We support fully personalized adjustments: customizable wire length, JST/PH series connectors, custom printed labels, neutral carton packaging and matched protection circuits based on your product structure demands. Both small sample batches and large mass orders are acceptable.

Wide Application Scenarios

• Mini portable Bluetooth speakers

• Wireless portable aroma diffusers & car humidifiers

• Wireless lavalier microphones & mini recording audio equipment

• Human body induction night lights & small monitoring cameras

• Other slim low-power portable consumer electronics
