The heated pouch is an one-size-fit-all battery cover that fit on virtually any type on on-board battery. It will protect the battery from harsh environment such as cold temperatures, wind and rain. It will also (and that is the most interesting part of it) keep your battery warm when you are shooting during extreme cold like we here in Montréal. It use hotshots or the rechargeable hand warmer to keep the battery warm so it can run for a longer period of time.
