Erik V1 Headband Betty R
The Erik mount makes it possible to use larger batteries on a headband, the mounting system is coming soon. The mount is not suitable for Clickbatteries!
This solution is not really made for runners, especially with the 6.6 Ah battery, however for professional use, it is sometimes interesting to get rid of the extension cord to gain more flexibilty.
6.6 Ah Smartcore
