Keep your battery pack warm under cold ambient temperatures with this battery warming tray from Much More. The Warming Tray is a warmer that can heat up your battery packs (LiPo or NiMh) before charging in the winter season. Cold batteries may lose punch, which means lower average voltage than usual, if you charge without any warming. The Warming Tray can be connected to Cell Master charger or Warmer Controller 3080 and it has a thermic wire inside and will keep target temperature where you set to. Available in anodised black, blue and purple.
