Description

Rechargeable battery extender, specifically designed to be mounted on motorcycle helmets.
Will work with Sena, Cardo or any communicator system that has a micro USB port and allows charging while talking.
During our tests, we could get an extra 8 hours of continuous talk time (tested with actual non-stop speech audio program from a FM radio station).
If no audio is sent – the two communicators still being paired and active intercom mode, we get an extra 20 hours.
This means that typically, on a Sena system and depending on how much talking takes place, you get between 16 and 27 hours total, including the internal Sena and the external battery.
The bonus feature is that everything is snap-fit and easy to remove for a quick battery change, if you don’t have access to 120VAC or 12VDC power for recharging after your day of riding.  So you can buy extra batteries and keep going for several days.  Each extra battery costs $8 CAD.
The kit includes:
  • 1 DC-DC booster module with micro USB male connector, cable is 20cm long.  If you need a custom length let us know, but allow an extra day to manufacture.
  • 1 lithium ion rechargeable battery, 700mAh, 4.2V, unprotected.
  • 1 Nitecore UM10 single cell charger.  Uses USB connection as power source.
  • 1 Curved slide-in helmet bracket
  • 1 piece of strong double-sided adhesive tape
Important notes:
  • Since the battery is unprotected, you must not let it overdischarge, or its life may be reduced.  As a rule of thumb, a full charged battery should be left in the module for 2.5 hours max, or as long as it doesn’t go down below 2.5V.
  • The system is not weatherproof and should not be used while it is raining, due to the exposed USB connection.
  • Helmet shown in photos is not included and only used for demonstration purpose.
When not in use, you can simply slide the module out of its bracket and put it aside.  The low profile bracket design makes it discreet.
