How many Lithium Batteries
Beginning of year I replaced My house Batteries,It had four Lifetime 250 amp hour 8D size batteries, I replaced them with four 280 amp hour Li Time Lithium Iron (LifeP04) Batteries. I wired them with bus bars and same size new 4/0 cables. Not knowing much about Lithium batteries I picked four 280 amp hour 1120 total amp hour, before I had 1000 amp hour, I thought I was doing the right thing. After a few months of full hook up camping and then dry camping I noticed one even two batteries are 100 percent on standby. After 3 days of no power running gen for 10 to 15 minutes a day for microwave only, We ran the full size refer TV stereo lights everything, At the end of 3 days batteries were still 48 to 50 percent, and one battery still full in standby (No solar), It needs more amp draw. In lithium still plenty of power still 13v, In AGM 50 percent almost dead. This morning I removed one of the four batteries now 840 total amp hours. This Royale is pretty easy on power, The Refer I replaced with new efficient refer, 2 New Magnum Inverters. I will test this, Do I need to remove another battery? How do you size Lithium for Buses???

Hi Art,
I am not a battery guy, so my question is to try to further understand your concern. Isn’t it better to have more capacity than needed for those occasions when you may need the extra available power such as running an ac unit.

That was my thought,But those batteries have so much capacity,Most of the time only 2 or 3 batteries are being used the other is full and in standby, And it varies which battery or batteries are in standby

I put 4th battery back in back to 1120 amp hours, I’m going to let smart batteries be smart.
