Well just got my batteries in today so i was going to try out my powerlab 6 with the power supply i got to power it. turned it on the fast charge set the charge to 10.0amp set the discharge to 10.0amps then started after about 5 minutes i was scrolling through the menus and found that is says my dc power supply is only do 12.1v at 2.5amp, something i did must be wrong. please help and thanks to everyone

I just checked mine (have a converted server PSU as well) and it read 12.8V @ 6.8A charging a 2S 5000Mah at 10A. What does the charging screen read? Are you at least getting a 10A charge rate?

And is that a good tight connection to your power supply?

No charging rate showed 1.99 when I set it 10amps I just tried it again and it actually worked at 10amps another question when it asks for discharge rate what should I put it at

I use high power mode for the most part and as far as discharge goes, I dont usually change that in any of the charging modes except storage charge. 10A is what I set it to altho my 4/5S lipos dont get anywhere near that.

What do you mean, "No charging rate showed 1.99?" I dont follow....

Not sure if you are stuck still, but two things....

Use high power charge mode. You caN change it but fast charge has a setting that limits charge amps.

Second, the screen you show is how much power you are pulling from your power power supply.
