I drive around with my Bumblebee, mapping the network. I was tired of the Anker battery sliding all over the place, and needing a huge usb cable. So I made this battery holder.
Using 4 screws (included), you can attach it under your bumblebee. Included is a custom length right angle USB cable to connect the BB to the battery. Then you can use some velcro, or sticky tape, to mount it in your vehicle.
Openings allow charging the battery, and plugging in cables. Designed to work with the Anker 325 battery pack, 20000mAh.
Do you have more than one BB? Available in different colors, so you can easily tell them apart with a quick glance.
