Replacement battery for Bose S1 PRO

The KingSener 078592 is a 14.8V 5500mAh lithium-ion pack built to replace the original 789175-0110 cell in the Bose S1 PRO Bluetooth speaker. It targets owners who need a fresh power source for portable PA use.

Sustained output at 14.8 volts

The 84.40 Wh capacity supports extended playback at consistent voltage rather than a brief peak. Li-ion chemistry maintains stable output through a full discharge cycle, so the speaker keeps its rated volume until the pack is empty.

Direct fit with original connectors

The pack matches the factory form factor and plugs into the existing battery bay without soldering or adapter cables. Common issues arise only if the speaker's charging board has failed, which a new cell cannot fix.

Questions about this item

How much heat does the 14.8V 5500mAh battery generate during all-day use with the Bose S1 PRO?

The Li-ion 078592 cell runs at standard operating temperature for its chemistry; no extra cooling is required beyond the speaker's built-in ventilation.

What must I already own to install the 078592 replacement in my Bose S1 PRO?

You need a compatible Bose S1 PRO speaker and basic hand tools to open the battery compartment and disconnect the old pack.

Will the 789175-0110 part number work alongside the original Bose charger I still use?

Yes, the 14.8V 84.40Wh pack matches the factory voltage and capacity, so the original charger charges it normally.
