hi, hope someone can give me some clues on this. i got aftermarket batteries (dji) tagged in amazon as "used like new", but the charger just keeps flashing green and 1s or 2s, or 3s flashing from time to time. seems the batteries are unbalanced, does the charger will balance them someday? this batteries were sold at 10$, on amazon. how come there are people selling unbalanced (unrecoverable) batteries? is a scam i think. should i just dispose them?. i have a voltimeter on hand how i can know how unbalanced they are?
