<div dir="ltr">Wrenches,<div>On battery heating, I hear a bunch of great ideas, incondecent lamp, simple thats untill it burns out, same with christmas lights, loose one and your toast, reptile enclosure blanket heater again great but on 24/7 for months on end what is the failure rate there? I have seen many outlets fail due to block heaters running in the nwinter cooking the outlet, socket and wiring in the outlet box. I have used Kohler Generator battery heaters and yes they fail too. I tryed a ceramic direct plug in heater, maybe 30 days and it was done. If this is for security then redundency and CC/inverter telemitry for monitoring temps is a must, we need an idea that is it Mars Mission Ready, Yes they are great and inovative ideas.</div><div>Brain stormen is Fun times</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Tue, Nov 25, 2025 at 1:14 PM Tyrone Houck 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 dir="auto"><div>Low wattage seedling heat mats work well too.</div><div><br></div><div><br> </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 25, 2025, 1:10 PM Dana Orzel via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank">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">

Hello all,<br>
I’ve been reading past posts regarding Battery Box Heating & am trying to find a simple way to heat an OSB insulated box for various LFP type batteries.<br>
<br>
One Battery Company’s tech support said he uses (at his own home) a 110vac incandescent bulb plugged in to a thermostat (inexpensive) that lets him heat between 32 & 50 degrees F.<br>
<br>
I had somebody suggest the same thing with some Christmas lights.<br>
The box & inverter & C.C. are in an un- heated garage on the Canadian border of NY. ( It can, & does get pretty cold up here.)<br>
<br>
Any suggestions?<br>
<br>
It’s Off-Grid & the owners want their Starlink & Security Cameras to be on year round.<br>
<br>
Thanks ahead of time!<br>
And, Happy Turkey Day!<br>
