The battery location for the down jacket is bothering my back, what can I do to improve comfort?

We understand that everyone has their own preference of where the battery is most comfortable. Since we are not able to move the battery pocket location anywhere else, the best solution is to purchase an extension cord through Ravean which allows you to have more freedom of where the battery is placed. The cord is a little over 24 inches long which allows you to place the battery in other pockets. There are built in openings inside the jacket to allow the cord to seamlessly run to the front left pocket.
