Just received and used for the first time to charge a LifePo4 12 volt 100 A/H battery. Nice little unit. Seems well built. Once I figured it out, it worked fine. The problem I ran into is that the Life Po battery was shipped with a low voltage as per fed regulations. The battery happens to be a Bluetooth battery, requiring you to switch the battery on as it is shipped "switched off". The life Po charging would not charge the battery while in the "off" position, too low a voltage for the charger to sense voltage, which is required to charge the lipo. I had to charge it, first, with the "lead acid" charging method for a minute to unlock the battery and then switch it over manually to Life Po charging for the remainder of charging and all was good. It charged fine. Nice having auto-10amp-20amp-35 amp choices. Seems like a great charger and reasonably priced, compared to the others that I researched. Better warranty than the others, as well. I think I made a smart choice. I like it. I think Vevor should update their instructions with a small note regarding the Bluetooth charging being a bit different.
