    Worked perfectly on two bikepacking trips

    Posted by Charles E Lee on Mar 2, 2020

    Follow on to my 2018 review; The V 15 Battery Pack worked perfectly on a 29 day GDMBR ride in 2018 and a 29 day road/gravel cross country ride in 2019. No problem keeping the Garmin running and all my stuff charged. Highly recommend!

    Great design, new favorite pack

    Posted by Fritz Stocker on Mar 30, 2019

    Bought for my son’s science project on dynamo charging. Worked perfectly (followed the write up on Voltaic site)! Now project is finished and I’ve taken over the pack as my new favorite mobile charging pack.

    Bought this to replace my last battery which lasted about 8 years, which is a long time for this type of battery. Excellent!

    Great for bikepacking with dyno hub

    Posted by Chuck on Jun 4, 2018

    I'm using this battery pack on a 29'er MT bike with SP Dyno hub, Garmin 810 and iPhone 5c. I can have the Garmin charging while the dyno hub is plugged into the battery and the Garmin doesn't try to turn off when I slow below charging speed. So, I'm charging the Garmin and adding power to the battery at the same time. Perfect! I've only done a couple hour test ride and don't know how all this is going to work 'for real.' I'll be riding the GDMBR next week. That should give it a good test. If I can do it I will report back. Great customer service too when I was asking questions.
