Overview

The Bose S1 Pro Lithium Ion Battery Pack solves a straightforward problem: it cuts the power cord. If you own a Bose S1 Pro and want to use it at outdoor gigs, park jams, backyard parties, or any venue where a wall outlet isn't conveniently located, this battery pack turns your S1 Pro into a fully portable system. It installs permanently inside the speaker's battery compartment, so once it's in, you simply grab the S1 Pro and go — no extra gear to pack or cables to manage.

Build quality follows Bose's typical standard — the battery slots in securely and feels like it was always meant to be there. The dual charge mode is a genuinely useful feature: leave your S1 Pro plugged into AC power at home or at a venue and the battery trickle-charges in the background, so it's always ready when you unplug. When you need a faster top-up, switching to Quick Charge mode (with the speaker off) gets you back to full power more quickly. At full output, the S1 Pro performs identically on battery as it does on AC — there's no volume cap or power-saving mode throttling your sound. For musicians, DJs, fitness instructors, or anyone who relies on the S1 Pro for regular portable use, this battery pack is less of an accessory and more of a missing piece.

Pros & Cons

👍 Pros

Up to 6 hours of battery life means you can get through most gigs, rehearsals, or outdoor events without hunting for an outlet
Trickle-charge mode tops off the battery passively while you're using the S1 Pro on AC power, so it's always ready to go portable
Full-volume output on battery — no forced volume reduction like some portable speaker batteries
Permanently installs inside the S1 Pro for a clean, self-contained setup with no external battery packs to manage

👎 Cons

Only compatible with the original Bose S1 Pro, so upgrading your speaker means this battery stays behind
Quick Charge mode requires the S1 Pro to be off, so you can't fast-charge between sets while still using the speaker
Lithium-ion chemistry means the battery will gradually lose capacity over hundreds of charge cycles
Adds weight to an already moderately heavy portable speaker system

Frequently Asked Questions

How long does the battery actually last during a live performance?

You can expect up to 6 hours at high-output levels. Real-world battery life depends on your volume — moderate levels will stretch it further, while consistently maxing out the S1 Pro will bring you closer to that 6-hour mark.

Can I charge the battery while using the S1 Pro on AC power?

Yes. The battery supports dual charge modes — it trickle-charges automatically while the S1 Pro is plugged into AC power and in use. When you're not playing, you can switch to Quick Charge mode for faster charging.

Is this battery difficult to install in the S1 Pro?

Not at all. The battery is designed to permanently install inside the S1 Pro's battery compartment. Once it's in, you charge it through the S1 Pro's own AC connection — no need to remove it.

Does using the battery reduce the S1 Pro's volume or sound quality?

No. The lithium-ion battery provides full-output use of the S1 Pro system without compromising volume level or audio quality. You get the same performance as when plugged into a wall outlet.

Will this work with the Bose S1 Pro+ or other Bose speakers?

This battery pack (model 789175-0010) is designed specifically for the original Bose S1 Pro system. It is not compatible with the S1 Pro+ or other Bose portable speakers.
