Replacement Battery for Bose S1 Pro

This 14.4 V lithium-ion pack replaces the original battery in Bose S1 Pro, S1 Pro Multi-Position PA System and S1 Pro System speakers. It delivers a 5400 mAh capacity rated at 77.76 Wh. The unit matches the OEM part numbers 078592, 789175 and 789175-0010. A built-in decoded chip communicates with the speaker exactly like the factory cell.

Fits the speaker without extra hardware

The pack measures 148.00 x 98.74 x 36.44 mm and weighs 551.6 g, matching the original footprint so it slots into the existing compartment. No additional cables, adapters or mounting brackets are required. Installation videos are widely available online for reference. The package includes protective foam for safe handling during the swap.

Sustained output with protection circuits

Overcharge, over-discharge, over-voltage and short-circuit protection circuits guard the cells during long sessions. The chemistry is rated for stable delivery across the full discharge cycle rather than brief peaks. A new pack reaches its best runtime after two or three complete charge cycles. Not suitable for users who need a higher-capacity cell or a different voltage platform.

Questions about this item

How long will the 5400mAh capacity last before the Bose S1 Pro shuts down during a full-volume gig?

The 77.76Wh rating at 14.4V gives the same energy as the original pack, so run-time matches the speaker's factory specification for a full charge.

Does the lithium-ion pack run hot or make the speaker fan louder after several hours of continuous play?

The replacement uses a fully decoded chip and built-in over-temperature protection, so thermal behaviour stays identical to the genuine battery under sustained load.

My S1 Pro shows part number 789175-0010 on the old battery — will this unit fit without any extra adapters or cables?

Yes, it is a direct mechanical and electrical match for part numbers 078592, 789175 and 789175-0010; the original connector plugs straight in.
