Review on 🔋 Koolertron 2.4inch Bluetooth Battery Monitor with Shunt: App-Enabled Wireless Voltage & Current Meter for Car Motor Boat RV Solar System - 400A 0-120V by Dylan Aaronson

So I don't "recognize" anything, it asks you to estimate your battery capacity. Something that pulls the remaining battery life. So if you don't know anything about your battery or how much capacity is left, according to various estimates, this is not the product for you and set it in the settings of the remaining battery life of batteries, it was gone every time and never repaired and it probably didn't make much of a difference but the temp gauge is in celsius and doesn't move at all even though the temp in my camper fluctuates quite a bit the app and readout screen doesn't show things like a cheap little wall monitor which is better than an app which only works within bluetooth range :( Plus, given how small and flimsy everything is I have to go with 1 star out of 10, my review may change later if the readings change
