I have a smartshunt in my connected to my 105Amp hour lithium battery. This morning, I checked the battery percentage and it was on 61% as I had been testing out my new fridge overnight. 5 hours later, it has been sitting in the shade with no way to charge the battery, I check it and it is suddenly on 100%. I do not understand how this is possible and it makes me feel uncomfortable that the smart shunt is not reliable and may be giving me false readings.
Why did it do this? Please help!
