AC to DC, why are amps very low?

[abwillingham]

Two different products. I have the DROK (20 amps) and a cheap CC/CV power supply (3 amp), which I thought was 10 amp.

Did you read the doco I linked?

yep. good stuff

You saw the bit where it suggests you charge the batteries as a serial pack with bms to get them close to the top before you finish them in classic parralel top balance fashion?

 

[abwillingham]

I did. thanks.

Why not?
Just saying don't without explaining why is not as helpful as explaining why.
Less chance your warning will be headed as well.

Computer issues prevented me from expanding on my comment.

The Drok unit is based on a range of power supply 'bricks,' common use in LED lighting. There is no current limit or constant current control, the current output is determined by the load. If the unit is overloaded it folds back, perhaps.
The resolution on the voltage display and the control potentiometer do not allow precise setting of voltage.
Would you recommend such a unit for a top balance application?

Nope, was just encouraging you to share your knowledge.
Sounds like its current limiting behavior is "hiccup".

I bought it as a charger, not a top balancer. But I thought about using it as a top balancer at one point.

@abwillingham , you had us running around there for a while ?
