Re: [RE-wrenches] LFP Battery Box Heating

[Jay via RE-wrenches]

Terrarium heaters  They make flat heaters in all sorts of sizes that you put below the battery.  I use a thermostat to control it.  Inexpensive and works Jay On Nov 25, 2025, at 1:06 PM, Steve Higgins via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:  I have heard of success from some using concrete curing blankets...  Something like this..  https://www.homedepot.com/p/Powerblanket-Insulated-Heated-Concrete-Curing-Blanket-3-ft-x-4-ft-Fixed-Temp-100-F-Cures-Concrete-2-8x-Faster-in-Cold-Weather-MD0304/305262566?source=shoppingads&locale=en-US&srsltid=AfmBOooWsz9ydnFCQqGmhiwcQwnsiBRsvA0cq7cs26sf8Ktx1P9fc9dXPZM Steve Higgins ⋅ Technical Services Manager t +1.902.597.4020   m +1.206.790.5840 f +1.902.597.8447   e st...@surrette.com CONFIDENTIALITY: The information transmitted herein is intended only for the addressee and may contain confidential, proprietary and/or privileged material.

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. I had somebody suggest the same thing with some Christmas lights. 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.) Any suggestions? It’s Off-Grid & the owners want their Starlink & Security Cameras to be on year round. Thanks ahead of time! And, Happy Turkey Day!
