A 1300 mAh battery eliminates the weekly charging routine that smaller lights demand. The Zecto Drive Max 400+ Rear from Lezyne stores enough capacity to run 16 hours in Day Flash mode or stretch to 70 hours in Femto mode when you need extended runtime on long tours or multi-day events. That battery size supports the light's 400-lumen maximum output without forcing you to choose between brightness and runtime—Day Flash mode uses the full 400 lumens but still delivers that 16-hour duration.

The six output modes cover different riding situations without unnecessary complexity. Day Flash handles bright sunlight conditions where you need disruptive visibility. Blast mode outputs 80 lumens for night riding when you want continuous visibility, running 3 hours 45 minutes on that setting. Economy mode drops to 15 lumens for 18 hours when you're commuting on well-lit streets and just need presence rather than high output. The Intelligent Power Indicator displays remaining runtime as colored LED markers and provides side visibility through cutouts in the housing.

The 2-in-1 mounting system uses either the rubber strap around seatposts or the integrated clip for attaching to bag loops or belt loops when you're off the bike. IPX7 waterproofing means the light handles rain and wet conditions without performance degradation. USB-C charging replaces the older Micro-USB standard—the waterproof charging port protects the connection during rides and faster charging protocols reduce the time plugged in compared to earlier Zecto models....
