Hello All. I’ve been running an all Victron system with 2x200ah batteries in my van for a couple years now. And with great success once properly configured:). I use the van periodically in colder US winter climate and when not in use, potentially up to several weeks, it is parked outside uncovered and connected to shore power. Shore power keeps the batteries charged and powering a few small loads and a space heater to keep the batteries happy and above freezing temperatures to allow charging. In lieu of operating an ambient space heater, I am looking for cost/energy efficient 12V heating pad/blanket options to install to keep the batteries at a healthy and happy temperature (say 50F?). Perhaps something like Battleborn’s heater kit but not as expensive. Ideally a Victron solution would be preferred but I don’t see that they have anything nor have I seen this Q&A in this forum. Any recommended suggestions? Thanks!
