Short answer: the Soundboks 4 for loudness, the Electrotec Stage One for sound quality and runtime. The Soundboks is tied for loudest battery-powered speaker and has a removable 40-hour battery, but it is very large, not stereo and trails the top Partyboxes on neutrality and bass. The Stage One is balanced with a dual swappable battery good for 100+ hours, though it costs $251 more and is tuned for loudness over deep bass too.
Buy the Electrotec Stage One. It is rated higher for sound quality, and the $251 you would save on the Soundboks 4 does not close the gap.

Cons: Very large. Not as neutral or as deep of bass as the above Partyboxes. Not stereo. External power brick for charging.

Electrotec Stage One: $1450 Electrotec Audio eBay
Pros: An exceptionally capable battery-powered PA: dual removable batteries deliver a claimed 100-hour runtime, and high-efficiency drivers deliver very high output with a measured 48Hz -10dB bass point. It adds app EQ, IPX6 protection, mic and XLR inputs/outputs, USB playback and low-latency SKAA linking, making it unusually flexible for events and performers. Measured bass extension of 48Hz (-10dB).
Cons: It prioritizes maximum output and endurance over truly deep bass, so it will not replace a dedicated subwoofer for low-frequency-heavy music. At 18.1kg it is a substantial carry, and its focused PA-style presentation is less suitable for wide, relaxed living-room listening.
