Hi Jay,

Within the next couple of weeks LiFeBlue Battery will be shipping the new Low temperature models. They have a heater built in and if the cells are below 32°F, charge current is diverted to heat the cells above freezing before transferring full charge current. All handled by the internal BMS. 

You can build a box and add a silicone type heater with a temp controller. I’ve bought items like that on eBay for about $25. See photo.

HI All,

I”m wondering if anyone has suggestions about how to charge a Lithium battery in RV or in this case Polarius in sub zero temps.

Are there batteries that have heaters built in, or is it still a custom design issue to build a heating system?  
( insulation and heaters)

Thanks,

jay
