found this one however amazon hey let go 12v songle chip
I bought one of these and it works well (lots of features), but I chose the 24V version of the one that @HRTKD linked to instead because I wanted °F instead of °C:

Errr.... Yeah. That's what I said. I bought the other one, but ended up using the 24V of the one you got BECAUSE I wanted °F.My 12 volt one uses ° F.
welcome, solar bear!Hi. I just installed my solution to this problem up here at 78 degrees north, inspired by lots of info on this forum.
Four 15w heatpads under a 4mm aluminium plate controlled by two XH-W3001 temp controllers kept my 8 LF280ks between 7-14 degrees celsius
(43-56 F) in a temperature of -15 to -18 C (5 to 0 degrees F).
5 days in theese conditions "cost" 60 Ah of the 560 Ah pack (2p4s) according to the victron smartshunt.
The battery box consists of 3/4"plywood lined with 2" of XPS styrofoam.
When my solar energy returns during March, it will contain itself. For now it should manage on its own just fine, as I am on-site atleast every 14 days. I recharge by a generator during our pitch black months.
I have a GSM monitor which will text me if I reach my set limits for temp and voltage.

ok!! Norway has no sun until march, just learned this!looking forward to March!
Yikes. I'm pretty sure I'm subject to SAD (Seasonally Affective Disorder). I get grumpy here in Colorado when the sun comes up after 7 and goes down before 5. I don't think I could manage it up there.Yeah, darkness from November to late Febuary, then som twilight, and on the 8th of March we should be able to spot the sun in the south.
Then it turns very quick the other way, as we have midnight sun from 20th of April until 22nd of August, solar power 24/7!
ok!! norway has no sun until march, just learned this!
-14 C today, so quite nice. The darkness is still here 100%, so looking forward to March! Do you have much sunlight down at 63°?

Here on Boston I store my electric motorcycle in an outdoor shed during the winter months at 50% SoC. Never had a problem. Same battery behavior during riding season for three years now. Storing below freezing is not an issue. But charging is.Presently, lithium batteries, which out perform flooded lead acid and AGM lead acid in so many ways, cannot be charged below 32 degrees and apparently should not even be stored below zero degrees. I guess if you need low temp tolerant batteries, go with AGM. Ayuh.
