Review on 30 Amp EPEVER MPPT Solar Charge Controller - 12V 24V Auto, High Input Voltage, Negative Grounded Solar Regulator for Lead-Acid and Lithium Battery Charging/Discharging by Don Devine

I bought this particular one because it got high marks for lithium battery charging on several van websites and Revain's reviews were mostly good. The product name states that it is powered by lithium batteries. I think so, but not out of the box. There are 4 battery types to choose from: Sealed, Gel, Flooded and Custom. There is no type of lithium to choose from. I googled a bit and found that it needs to be set to the user's battery type in order for it to work with my lithium batteries BUT! You cannot change any of the user settings without a dedicated cable (not included), PC software or Android app (requires optional custom cable). Windows only, no Mac or Linux, Android only, no iOS version. Note that none of this is predetermined. The default settings for sealed batteries are about the same as needed for lithium batteries, so I'll use them until a dedicated cable arrives.
