Weird, my screen was surprisingly accurate. What is the voltage of the battery when the charger is connected when its saying it's fully charged? I had a fairly cheapo charger that never fully charge a while back unless I dropped it down to 5a charge for the last part of the charge around that same SOC and I ended up chucking it. It was one of those HTRC ones that claim to do 3 different battery chemistries, including LifePo4. Just a thought.
