I did weigh those options, the reason I went for the LFP with heating was that if I did discharge the lead acid too far it would freeze, and then I could never charge it until it thawed (I had this happen to a car battery once). I am also monitoring the "charge cycles" of this battery through...

Nice setup! Thanks for sharing! Yeah, that sounds like a good way to go for me next year. More FLA capacity and keep it charged enough to not freeze. What mechanism do you use to do the low-voltage shutdown? I see you mentioned the Renogy Rover and not the Elite, I believe that has a "load"...

Thanks for the info on #2. On #1, I am assuming that there is no communication from the Charge Controller to Battery via the RS485, they seem to both be "slaves" and they are meant to connect to the Renogy hub/controller they sell separately. So what I have in my setup is a microcontroller...

Thanks for the input, I think the suggestions for insulating the battery are great. Definitely something I will do next winter. I suspect once it is fully buried in snow that will help a bit with insulation (it is in a plastic battery box as well, but that isn't insulating). I didn't research...

Oh awesome, thanks! I didn't know those existed.

Hi, So I purchased these three items: 2 x 100W Renogy Solar Panels Rover Elite 20A MPPT Charge Controller Renogy 12V 100AH LiFePO4 with self-heating I am planning to set this up at a remote location over the winter, hence the self-heating battery for those cold days (down to -30C perhaps). It...

Alright, the first day of sun in a week or so! I just wanted to say that the description of the heater/charging from SolarShed is spot on: https://diysolarforum.com/threads/renogy-smart-lithium-battery-with-self-heating.25782/post-355513 My battery hasn't been charging for a few days and I can...

I wanted to add an update after speaking with Renogy regarding the modbus communication and the battery heater. I mentioned to them that I wanted to know if there were any configuration options via modbus to allow the battery heater to function using internal battery power. So they did reply...
