Ultra-rapid charger for NiteRiding mountain bikers! Charge your packs in a little over an hour (depending on pack capacity), or if the pack's not completely depleted from the previous ride, top it up to full charge!

The Xeno-1 is for 6V NiteRider battery packs, and operates from a vehicle's 12V accessory outlet. The Xeno-2 is for 6V and 13.2V battery packs, and also operates from a 12V accessory outlet with it's internal 20V DC-DC converter.

Both chargers support NiCd and NiMH cell chemistries (selectable via jumper), support all the cell capacities (3.8Ah, 4.0Ah, 4.5Ah, etc), and have a 7-segment LED display indicating the charge status from 0-9 to 'F' for Full.

The Xeno-2 charger even has an audible beep when charge is complete, so that you don't even have to look away from the road while driving to know you charge is complete and you're ready for that night ride!.
