<div dir="ltr">An excellent idea and one that is catching on for DIY also. There is a potential issue using those at below freezing temps, as with all Li batteries they should not be charged at below freezing temps. You'd want to look for one with heated batteries. There are more and more brands of these power boxes available, but I'm not sure how many, if any, have heated batteries. I'd hope that the heater would be powered only from a charging source, but you'd probably have to ask the manufacturer. I think it's also better to find and use those with LiFePO batteries for safety. For industrial use it would be great to find something with the more expensive LiTO batteries which are ok with lower temps, but I don't think there are any battery banks with these, much less power boxes. <div><br></div><div>Brad Bassett</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jun 8, 2024 at 3:34 AM Peter Giroux via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg-5707228334939903190"><div lang="EN-US" style="overflow-wrap: break-word;"><div class="m_-5707228334939903190WordSection1"><p class="MsoNormal"><span style="font-size:11pt">Jason<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11pt"> Saw your post and wanted to share an idea or two.
