Ive been using Thundxer AC-6 for a month now with no problems. Today I'm balance charging a 5300 mah 2 cell @ 5 amps and just happened to look at it when voltage hit 8.4 v. Charger did not shut down so I unplugged and checked battery with meter and it only showed 8.22v. Has anyone seen this before? Is there any way to calibrate this charger? BTW, Im new to lipos.
Thanks in advance.
