I have the Efest LUC Multi-function Smart charger. The numbers seemed like a nice but not necessary feature when I purchased it. What I've found is that seeing 3.7V when I put the battery in, or 3.2V, etc gives me a better feel for when I'm pushing the batteries further than I'd like to. Seeing 2.1V generated a yikes response. I don't need to see the numbers increasing as it charges. Its just the initial reading which really gives me feedback on how deep I'm discharging batteries.
