What Our Gearhead(R) Experts Are Saying:"This Enduro pack is the battery I trust for cold chairlift days-runtime bumps up just enough that I'm not swapping every session, and the MAX actually keeps recording instead of shutting down as soon as temps drop below freezing."On those frigid park laps and ridge scrambles when fingers sting and batteries usually bow out early, MAX Enduro Battery keeps the GoPro MAX rolling long enough to capture the full line instead of half a run. A 1600mAh lithium-ion build tuned for cold conditions means this pack holds power down to roughly 14degF, so footage keeps stacking up even when winter is fully locked in. For trips that span everything from frosty dawn setups to warmer afternoon sessions, the wider operating window helps avoid missed moments between quick hits, tree runs, and summit panoramas. On back-to-back days, extended recording times make edits easier by reducing mid-session swaps and helping each charge cover more clips. The battery drops straight into the MAX with no extra housing and charges on standard MAX charging solutions, so it works seamlessly as either a primary power source or a dedicated cold-weather backup in the kit. Used as a spare, it buys extra insurance on long travel days, where a little more runtime often means landing the last shot before light fades.
