I bought this Renogy 200Ah LiFePO₄ battery and the Renogy ONE Core G1 display about three years ago for my travel trailer. It originally cost around $1,000 for the battery and $200 for the display.

The battery and display communicate directly over Bluetooth, so no wiring is needed. It’s been a solid setup for RV use, especially when I needed reliable power for my Starlink while camping.

A few months ago the battery became slightly unbalanced and the BMS shut down once overnight. Before a big trip, I replaced it with a newer Renogy 200Ah that requires the G3 display—so this G1 display is no longer compatible with my new battery.

I charged and balanced this battery using my Victron charger, and the cells appear equalized again. For typical RV 12V loads (lights, fans, water pump, etc.) it should work great for years. I’m not certain how it will perform with heavy loads like a microwave or hair dryer, so please keep that in mind.

Just hoping to get a little value out of it and pass it on to someone who can use it.
