Macna Bluetooth Battery Back-up Kit

When you disconnect your heated gear from your bike battery to make a pit stop or to stretch your legs, your gear will lose its juice. Resulting in you having to re-activate all your gear when you're about to set off again.
This out-of-seat Bluetooth® battery will keep your settings active for a while after you have disconnected from your bike battery, kind of like a standby mode. So, when you re-connect to your bike battery, you're instantly ready to ride again.
It's important to point out that this is not a separate battery but more like a backup save button.
