Hi Nathan,
I live in Minnesota, so cold weather is very common. We just came
The Leaf battery includes PTC heater elements that the BMS controls. I
don't know what temp the turn on at though.
I'd probably look at some of those "terrarium mats" for putting under
gravel in the fishtank/terrariums to keep reptiles "warm enough" as they
are designed to heat to a

The CALB batteries I had were definitely NOT happy if I tried charging
them below 40F. Fortunately, living in San Diego at the time, that was
not a worry. Now that I live further north, I do have to worry (or at
least once I get a new EV hobby build). You are right in that you need
to check
In addition to water bed heaters, check out the solid material plant
heaters.
Another possibility is the Farnham silicon rubber heaters:

It heavily depends on the electrolyte / cell chemistry. I have
batteries from a Think City (made by EnerDel) and they are spec'd to
operate down to an extremely low temperature of -20C. That's -4F. I
don't think I'd charge them very hard at 0F but it seems that's in the
temperature range to be
Hi Nathan,
Back in the days of lead-acid, we used water bed heaters under the
batteries to get them to an optimal temp for charging and discharging
(about 100 degrees F). I'm thinking that you are looking to keep your pack
more in the area of 50 degrees, but I expect that the same method would
Hi all,
I live in northern utah, and it can get fairly cold here in the
winter(close to 20 fahrenheit in the night)
I am using nissan leaf batteries in my Geo Metro EV conversion. The leaf
batteries, as with most other lithium batteries, is not supposed to be
charged below 32 degrees fahrenheit.
