Renogy Rover Settings for a cheap LiFePo Battery

[helloecho]

First I'll start with my gear:

• 200W 24V NewPowa Monocrystaline Panel
• Renogy 40A MPPT Rover Charge Controller
• Renogy 500A Battery Monitor with Shunt
• EcoWorthy 50Ah 12.8V LiFePo4 Battery

My primary goal is to properly set up the battery for use off-grid the next week. Then setting things to a more moderate level for storage when I come home.
I've read these two threads[1,2] on the Rover controller and am starting to understand the settings. However I'm still stuck on the following two things:

1. Charging the battery to 100%. The EcoWorthy battery manual says to charge at 14.6V, but in its own manual it says this is in its overvolt range. This also seems dang high as well as higher than the high end of what other folks seem to set their rover controllers to charge at. My controller was set to use the aggressive built-in Lithium settings but I realize now I should set them lower. Do I set my charge controller at 14.4v and wait until the battery hits 14.4v to consider it at its true 100% capacity?
2. Setting up the battery monitor.I'm not exactly sure what voltages to set in the monitor's settings, and when to press the button that says "Ok the battery is at 100%". Right now the monitor reports battery voltage and load amperage, but not battery capacity; it just displays 0%.
   1. I'm not sure on what voltage min and max to set here. Should max be 14.6? 14.4? Should the max be the same as the max voltage that I set in the charge controller? What should the minimum be set to? The Battery's manual says "nominal voltage" is 12.8v and "voltage range" is 10-14.6. That seems...like a large swing for the min and max though.
   2. UPDATE: I just read this thread: https://diysolarforum.com/threads/renogy-500a-monitor-settings.67525 and I now I understand these voltages are triggers. Is my understanding correct: You manually tell the monitor when to consider the battery at 100% or 0% and from that moment on it measures the amount of amperage entering or leaving the system and keeps a tally which it reports as the amount of amp hours available? This entire time I was thinking it was basing things on the battery's voltage...oy.

Thanks for any help and advice.

For such a small system, you probably don't need the shunt.
Just set the Rover to the default Lithium setting and you should to good to go. If you want to use custom settings, set boost, float, equalize voltage to the same. 13.8V is a good charging voltage. Then turn off equalization by setting the equalization time to 0. Keep in mind that if you later change to a 24V or 48V battery, you will still use 13.8V on the Rover because it will automatically double or quadruple it for you based on the system voltage.

Checkout this message for issue #1. It may be helpful on how to determine when the battery is at or near full charge.

Renogy 40a mppt Li settings

This is a great thread for those using a lifepro4 with a rover 20/30/40. If others find themselves here I’ve come to learn there are 2 different Bluetooth apps for the rovers. The original was the BT app which had more parameter adjustments in the “user” setting. Renogy no longer updates that...
