This cell Analyser, Charger, Discharger is/was fantastic, i think one of the best so i mounted 2 to a piece of wood and fed it from a 12v 5A mains psu.. its been a good charger until now, found it powered down (other one was still on).. assumed it had blown up so went out and bought another 3.. i want to get through batteries quicker!! Anyways, this one still powers up. its doing some wierd stuff and appears to crash which us why im selling it spares and repairs...
