18650 26650 Rechargeable Li-Ion Battery Charger

A dedicated charger for lithium-ion cells with two independent bays, so each cell is charged and monitored separately rather than as a pair. That independence matters: cells at different states of charge in a shared circuit charge unevenly, which shortens their life. It applies the correct constant current then constant voltage profile and terminates at 4.2 volts, which a plain DC supply cannot do. Two independent bays charge cells separately; Correct CC-CV profile with proper termination; Accepts both 18650 and larger 26650 cells; Per-bay status indication
