Additional 7.4V Battery

Nice to have an extra battery so you can keep warm all day!

Great product

My wife and i are older couple, temperature plays a huge role on us, her more than me, she has been wanting something to help keep her warm as she gets cold easy, I was doing some research for something that she could wear while we ride the motorcycle, I found your jacket and was researching it, my grandson came into my office while I was looking and he asked me about for her birthday (hence the reason of no fast response to this email), given that your jacket had the larger warming zone that covered more of her body, this is what I was considering, but the price and lack of funds I was hesitating, the original idea was he wanted to split the cost with me, so I went ahead and ordered it with the fear that this product would be a waist of money due to quality. After ordering it he decided that he wanted the gift to be from him and he wanted to pay for it with money he had saved, so I let him, speed forward to 27 Feb he gave that to her for her birthday, she was skeptical as to weather it would work, but she started wearing it and after a couple of days of cold weather she was wearing it pretty much all the time after that point, now every time the temp drops to 55 or below she has it on. She is very impressed with how well it works and how comfortable it is. You have an excellent product (so far) I would recommend it to anyone, I am even considering ordering one for myself now. Thanks Mark Hutchens

Works Great!

I purchased a second battery for my vest. I prefer this new battery over the one that came with the vest. Better quality battery.
