the charger i am using is the sky rc e3 .
its a genuine one not a clone.
bought it from robu.    https://robu.in/product/skyrc-e3-ac-2s-3s-li-po-battery-charger-v2-original/

earlier it charged to a perfect 4.19 volts .
recently its been charging to 4.4 volts and even 4.5 volts.
what is going on. ?
did i accidentally turn on hv charging in it.. or has it just gone nuts.
3 months old
