Selling an ISDT SC-620. Been in service for a few years and still works like new, only damage is some scuffs on the case. I got myself an 8s charger, so expect this one to have abandonment issues upon arrival.
This balance charger can work with all of the common lithium battery chemistries, as well as nickel and lead. It runs off a DC power supply up to 24V, charges up to 6s and 20A, and also provides storage, discharge, and internal resistance measurement functions. Asking $50 shipped within the continental US.
