Short answer: the LG Xboom Go PL7 for battery life, the Ultimate Ears Epicboom for a floating IP67 build, though neither ranks well in its class. The PL7 runs 24 hours with detailed sound and nicely balanced bass, but it has a 9kHz peak and does not sound good. The Epicboom is IP67 rated, floats and runs 17 hours on USB-C, though it has not very deep bass for the size and distorts around 70-80% with bass thuds. Both are rated below 3.0/5 among the 97 large speakers, and the Tribit Stormbox Lava, ranked #3 at $100, is a better place to start if sound quality matters.
Buy the Ultimate Ears Epicboom. It is rated higher for sound quality, and the LG Xboom Go PL7 is discontinued, so it is only available used.

LG Xboom Go PL7: $70 Discontinued LG eBay
Pros: A 1.45kg portable with IPX7 protection, a claimed 24-hour battery, aux input, speakerphone capability, stereo pairing and Wireless Party Link. It plays fairly loudly for its size with few obvious artifacts, and its LED-rimmed passive radiators make it a practical, fun choice for casual outdoor listening.
Cons: Independent testing finds weak low-bass and top-end extension, a narrow soundstage and uneven off-axis response. The default Sound Boost processing can make the upper mids and treble aggressive; turning it off improves balance but does not transform it into a detailed or deep-bass speaker. It has no user EQ to properly tailor the result. Discontinued.
