Review on Renogy 12V 100Ah Lithium LiFePO4 Deep Cycle Battery With Bluetooth,2000+Deep Cycles,Backup Power Perfect For RV,Off-Road,Cabin,Marine,Off-Grid Home Energy Storage by Robert Ogrodnik

I am very happy with these batteries for my RV. I have three wired in Parallel. I liked the extra long terminal screws supplied, as I have several lugs on some terminals. Good sturdy terminals, too. I also like being able to shut down the battery when the RV is in storage. The batteries will hold their charge indefinitely in this manner, without having to keep a charger on them. Tech note: you do have to remove one lead on each battery in order to shut them down. They will not shut down when tied together.Dramatic improvement over my old lead-acid batteries. I would buy these again.
