Propane has same issue’s as batteries! Tank with frost up in cold when used and with have to be warmed to build pressure back up in tank after each use on the auger!

All batteries get “cold soaked”! I put my ION batteries and dewalt cordless batteries, which I use my drill attached to the 4″ auger for jigging holes, in a small soft insulated zippered cooler bag and I put 2 to 4 hand warmers in the cooler bag(temperature dictates how many warmers) to keep batteries warm. I put batteries back in the bag once I am finished drilling my holes. I drilled 35 holes yesterday in 14″ of ice on one charged ION battery! Again, all battery operated tools and equipment come with a disadvantage with the cold. Move to Alaska if you wish to challange this advice, even car batteries have to have a heating pad on them and plugged in when not in use! Then post your opinion on how battery operated stuff should work anytime! Until then, shush! I also bring a 400 watt(minimum) inverter that plugs into truck cigarette lighter plug to recharge batteries if I to recharge battery. This ION auger is awesome! No gas, oil, not starting, blah blah blah! Highly recommend this product! Again, all battery operated stuff has some inconviences!
