Cameron Sino J406/ICR18650NH-2S 3400mAh 7.4V standard battery

Replacement battery for Bang & Olufsen speakers

This lithium-ion pack replaces the original cell in the BeoLit 15, BeoLit 17, BeoPlay A2 and BeoPlay A2 Active. It delivers 3400mAh at 7.4V with a fully decoded chip that communicates with the speaker exactly as the factory unit does. The pack measures 132.05 x 22.20 x 18.50mm and weighs 97.3g.

Capacity and runtime

Rated at 3400mAh and 25.16Wh, the battery supplies enough energy for extended portable listening at moderate volume. Runtime falls as output level rises, so very loud playback will drain the pack faster than background-level use. The two-cell 18650 configuration provides a flat discharge curve until the protection circuit cuts power at the low-voltage limit.

Thermals and protection

Built-in safeguards guard against overcharge, over-discharge, over-voltage and short circuits, keeping cell temperatures stable during normal charge and discharge cycles. The protection board interrupts current before heat becomes an issue, so the speaker chassis remains cool to the touch. No active cooling is required and the pack operates silently.
