Hi everyone, I have campervan which I am planning on upgrading to a lifepo4 setup. I live in the PNW and do a fair amount of ski trips in the winter so I will be exposing the batteries to freezing temperatures from time to time. I have tried to find as much information as I can around what to do to manage lithium batteries in cold temps but no where seems to indicate the a recommended or best practice setup. I am hoping someone could shed some light.
In my system I have alternator charging as well as a 200w solar with a Epever MPPT controller. Most batteries BMS have some sort of low temperature cut off for charging. But when the BMS cuts off charging, wouldn't this damage the Solar Charge Controller as it's always recommended to connect the SSC to a battery and the low temp cut off disconnects this? Since many SSC's have external temp sensors, are they smart enough to cut off charging at a temperature?
The battery I'm looking at is the older Renogy lifepo4 as there's some sales right now, but its especially annoying as when it goes into protect mode you cant even turn it on unless you have a Renogy charge controller. So I'm seeing if I can find a way to not let the battery get below this temperature.
Is there a best practice to handle this? Some are saying use a heat pad and a temp sensor which turns it on. But doesn't seem like everyone agrees. Hoping someone can answer this.
Thank you,
Alex
