If you’re sourcing a battery pack for Bluetooth speaker production, you already know it’s one of the most critical components in your design. The right battery pack determines your speaker’s playtime, safety, and overall user satisfaction. The wrong one leads to returns, warranty claims, and brand damage.
At A&S Power, we manufacture custom battery packs for Bluetooth speaker OEMs worldwide. Here’s what every buyer should know before placing an order.
What’s Inside a Bluetooth Speaker Battery Pack?
A complete battery pack for Bluetooth speaker typically includes:
| Component | Function |
|---|---|
| Lithium polymer or 18650 cells | Store and deliver energy |
| PCM (Protection Circuit Module) | Prevents overcharge, over-discharge, and short circuits |
| BMS (Battery Management System) | Monitors temperature, balances cells, and communicates status |
| Wires and connectors | Connect the battery to the speaker’s PCB |
| Insulation and packaging | Protects the cells from physical damage |
Some suppliers cut corners on PCM or BMS to reduce costs. This is a mistake – a battery pack without proper protection is a safety hazard.
3 Key Specifications to Get Right
1. Capacity (mAh)This directly determines playtime. A 2,000mAh pack typically delivers 6-10 hours, while a 5,000mAh pack can deliver 12-18+ hours. Match the capacity to your target market’s expectations.
2. Physical Dimensions
Your battery must fit inside the speaker enclosure. Lithium polymer cells can be custom-shaped to fit tight spaces – as thin as 3.0mm or curved to match your design.
3. Discharge Rate (C-rate)
Bluetooth speakers with powerful amplifiers need higher discharge rates. A 1C battery won’t deliver the same bass response as a 2C-3C battery. Don’t overlook this spec.
Why Supplier Choice Matters
Not all battery pack for Bluetooth speaker suppliers are equal. A reliable supplier should offer:
-
UL, CE, RoHS, and UN38.3 certifications
-
100% final testing on every pack
-
Batch-level traceability for quality control
-
Engineering support for integration
-
Clear communication and realistic lead times
At A&S Power, we provide all of the above. We’ve helped dozens of Bluetooth speaker OEMs bring their products to market – from compact portables to outdoor models with 18+ hour playtime.
