Battery life

Although the 2 hours on HI is ok'ish and there is a pocket for a spare battery, there is no good way to change the drained battery to a fresh battery. Both batteries need to be plugged in simultaneously. Same with the charger. I wish to charge both batteries simultaneously. I also inquired about whether the batteries can be charged via the USB port. Waiting to hear back.

Great service!

The extra battery I purchased was a dud, but fortunately the service was not. The battery was promptly replaced and the new one works well, like the other two batteries I have. Overall, I am pleased with the product and the company.

Battery seems to last

Overall, the additional battery I purchased charges in a relatively short period of time and lasts quite a while in my vest. I have not run the vest on its highest setting because I've only worn it while on the move, but I believe I can easily make it through an entire day in a tree stand with just two batteries.


the vest is awesome. had some trouble with the battery which they replaced. All my messages were answered promptly and new battery was sent out quickly with no hassles.
