[RE-wrenches] LFP Battery Box Heating

Tue Nov 25 20:56:19 PST 2025

Wrenches,
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.
