oldjohnt Posted December 24, 2022 Report Share Posted December 24, 2022 Congratulations rb and thanks for the info, using heaters to protect Lithium batteries and prevent any damage is so simple, basic and a no brainer as far as I'm concerned. With over 50 years of RVing and lots of dry camping I long ago converted to Lithium, am happy and never looking back...
