New charger worked fine out of the box, 2 weeks later it cycles (clicks) every few seconds and only about 1 amp output and about 4 volts shown on app... Should be around 27 volts. Lights show Bulk and LiPo, as they should, but not getting 7.8 amps like I did initially. Batteries are at 80% and 60 degrees. Same results using 3 amp output setting. Smart BMV shows spikes on the graph matching the clicking.
