I have an IP65 charger connected to my 120AH Lithium battery. The battery in its battery box has shown an available charge of only 10.1v-10.4v when it has stopped working on my 45L camping fridge (after only a few hours) recently, yet the charging history Vstart number suggests the last few charges have started with the battery somewhere between 12v and 14v. Am I missing something? Why would the battery be dying at <10.5v (which is about the cutoff for low voltage for the fridge) yet allegedly be at 12v-14v when plugged in to charge?
