Core UAC-40 help needed please !!!!!!!

[RDG 40]

Just getting used to my charger above.

Can someone please help me with the following two questions:

-What is difference between charge function and fast charge function, and does it damage LIPO's in anyway or reduce life either one?

-Storage mode how do you set it. I know how to get to it but it only goes to 1.0 as apposed to say my 5000 packs that i charge at 5.0. What should i be doing to make sure the LIPO stores correctly with this function.

The instructions are pants tbh and im very keen not to naker my new LIPO's

I run some 5000 50c and some 4200 35c for clarification.

thanks in advance
