Hi Tony. Sorry to report the following on my Pink OCDAY DP6:
I'm feeling down about my OcDay DP6 cause line 4 on a 4S balance charge is losing line 4 regulation in the unit. I swapped around the cells to see if the problem migrated but it stayed on line 4. The line monitor readout will say 3.665 volts or worse even though I measure 3.33 or so at the cell itself, and later the unit will 'balance fault' and no longer permit balance charging. I also disassembled the balance leads to the cells and relocated them to other other cells when I reordered the cell locations, but no change, the problem still remained on line 4 out of the DP6. Even if I can get the unit to run a balance cycle, it will either balance fault or never figure out how to finish up. The only way to get to a good charge point now is run Storage charge instead; so something is flaked out inside the DP6 and so that's why I'm down on this unit. Opening it up to look inside but not expecting many options. This unit is fairly unused so it's premature to flake out like this.
I've past training and industrial work as am electronic tech. I did some short analysis on the balance lines final section and report So far I have not found any anomalies between any resistor resistance values, diodes are good, and transistor forward and reverse bias resistance values are comparative for all the balance lines in the final output section. I'll need to Amazon me a cheap digital scope, been wanting one anyway whether or not it helps me on this... Some pictures of the circuit board section I examined will be linked here soon as possible
