Doing a long adventure race or 12 hour ride? Order a spare battery & have it charged ready to go!
Use drop down menu to select which light set you are ordering the battery for:
- Speed I & II lights (1000 lumens) are identical.
- Ray III & Ray IV are interchangeable (1300 & 1500 lumens) with Speed batteries but there will be a reduced run time.
- Ray V light is only for Ray V.
