I have a dual battery setup now but when we first got our ARB 50 I could go two days of the truck sitting and still start our '10 FJ Cruiser. We went 2 1/2 days once (Texas Summer) and I couldn't start the truck (prior to the dual battery). My battery is and has been a group 31. The 2 1/2 day...
I'm open to other options... For $$ reasons, just not wanting to replace the National Luna setup.
I'm not sure it would keep the main battery above 13.1 volts to keep the solenoid engaged, especially since the house battery is the one with constant loads. I'm only guessing but once say...
I have the National Luna battery manager (https://www.nationalluna.com/product/battery-manager-diy-kit). I'm not sure running the SunSaver 10 to the start battery would keep the voltage high enough to keep the isolator connected....
Are there any other dual battery controllers out there besides the SunSaver Duo?
I've been running (5+ years I think) the SunSaver 10 on the house battery and now I'd like to add the starting battery as our rig is no longer a daily driver. It'll only have a 100w panel.
I to have been reading this for a few years now and looked forward to getting a email telling me there was an update. Sad it has ended but they had a GREAT adventure and I thank them for sharing it with all of us!
