Two 18650 load simultaneously but with individual cell monitoring.
In each case, an LED indicates the status:
No battery in the bay -> green
Charge the battery in the bay on -> red
Battery fully charged -> green
Although these loaders Although loads after charging only with maintaining current (~ 0,1Ah), please nevertheless never let the charging process unattended.
Loads with 1A per shaft and is of the price / performance unbeatable. Already have 3 pieces of it because my Supbeam require X40 and K40 6 x 18650 and I'm usually too impatient.
Strong buy recommendation.
