Charging 2 18650 at different voltages

[Dragon8oy]

Hi newbie question here

Im using the Pila IBC charger and was wondering if its safe to charge 2 different voltages of 18650, such as at 3.5 volts and at 3.9 volts?

If one of them was fully charged do i have to remove it from charger straight away or would it be safe to let it trickle until the other becomes fully charged?

Can i remove the 18650 when its on trickle or do i have to switch off the charger first?

Thanks

The Pila IBC has independent charging channels in its two-bay configuration. You may have one fully-discharged cell on one bay and a half-discharged cell on the other bay and have it charged together. The half-charged one will just terminate earlier than the other one. Just be careful when you the remove the first fully charged cell, a slight tap or movement on the charger will oftentimes make the charging light turn to 'green' pre-maturely. Just push the 'reset' button to complete the charge of the second cell. Charge away!

I usually just lets the fully charged battery sit tight in the charger till the less charged to complete, this is to avoid what tatasal also experiences.
