Hidden function LiitoKala Lii-PD4
With the LiitoKala Lii-PD4, you can lift the 18650 from a deep discharge. When first installed, the LiitoKala Lii-PD4 identifies the 18650 with a deep discharge of about 1 volt as NiCd and finishes charging very quickly, but when re-installing the 18650, charging begins in standard mode.
