Lithium heating pads
Has anyone added heat pads to your lithium batteries so you can charge below freezing. If you did what did you use and how did it work
Forum Discussion
Any pictures of your set up? Also, what waste tank heater model is it? An Auto temp kick in sounds great! Tia!

I have. I added a waste tank heater stuck to a thin aluminum plate. That goes directly under my 6 LiFePO4 batteries. I also have a battery temperature probe attached to my Victron setup to prevent charging if the temp goes below 5C. Batteries are surrounded by foam board insulation.
I considered the grip heating pads, but the waste tank heater has the automatic temp kick in, so I went with that instead. Seems to work very well. It draws down roughly 6 amps per hr and comfortably kept the batteries 10 degrees above ambient. I didn't get a chance to measure under colder conditions as our season wrapped up first.
