Unlike standard cylindrical cells, our flat-pack Li-Po battery maximizes internal volume efficiency. Here is why product designers prefer this model:

• Ultra-Slim Profile: At only 3.0mm thick, it fits perfectly into sleek, pocket-friendly charging cases without adding bulk.
• Optimized Capacity: With 100mAh (0.37Wh), it provides the ideal balance of size and power, capable of recharging most TWS earbuds multiple times.
• Built-in Safety First: Equipped with a robust Protection Circuit Module (PCM) to prevent over-charging, over-discharging, and short circuits—essential for consumer electronics safety compliance.
