the derek thermal battery bag

do you happen to be working in the dead of winter off a truck that never gets above 55 degrees and somehow are expected to keep several batteries charged that likely also don’t have the freshest cells and maybe even are lucky enough to be using a 26v camera? This has a highly durable vinyl coated nylon exterior and a thermal interior made of a foam with an aluminum reflective coating. Double foam bottomed to reduce the ground temp radiation. nice big easy to see handles as well as a window to be able to check voltage without opening the velcro sealed lid. Can be made in VCLX, Bebob or whatever other weird batt your rental house is kind enough to offer.
