1.1 oz, battery lasts 8 - 12 months.
LiquidAider wireless button mounts next to your grip. A thumb actuated button sends a wireless signal to the pump and water squirts into your mouth!
The button has user-selectable modes for momentary (press and water squirts as long as you hold), or burst mode for 2, 3, or 4 second burst modes where a simple press and release of the thumb button results in a 2, 3, or 4 second burst of water. At 1 liter per minute, 4 seconds is a lot of water.
The LEDs also indicate when the button battery is at 25% capacity (2 months or more left), and when the pump battery is at 25% remaining capacity (10 liters pumping left).
The button pairs with any number of pumps - perfect for team races like Baja 1000 where the bike is shared!
Check out the button guard that is included and protects against crash impact and brush/limb impacts.
