<1st Question>
Yes, I tried higher amp. in 1st & 2nd stage beofre.
In fact, I recommend you to use high amp in 2nd stage. 1st stage should be used for lower amp, because battery is still sleeping at the beginning. If you put a bunch of power from the beginning, battery may be surprised...(may be Damaged)
Therefore, you can try this also.

1st 500 mA 3.5A(static)
2nd 3500 mA 6 or 7 A (static)
3rd 5000 mA 4.5A
delta peak 24mV / Temp 45 degree

<2nd Question>
You don't have to use delay in this case. Because I put delay mode in the profile. Please take a look 2nd stage carefully.
Why I can put 20 mA at 0.2A???
This is because I want to make battery cooler.
It takes about 10 minutes delay if you use my setting for 2nd
stage.

If you use ; 2nd 3510mA 0.2A setting, it takes abnout 5min.
cool off time.


<3rd Question>
What is the differences btw static, impulse, and linear...
Maybe, you confuse these.
At first, we can divide linear charger and multi stage charger.
linear charger is that we cannot change the charge setting while
charging, like LRP Competition or Reedy charger stuffs.
Since you cannot change the charge curve, we call it linear charger.

Multi stage charger has a function to be divided in the charg
setting in charging process, like Record Breaker, Front Line2,
Cell Master, Pit Bull X3.

Now, the differences btw static and impulse is ;
impulse mode let battery stimulate by using high current within
a few micro sec. static is none.

<4th question>
You can use the same profile even you run whatever you can run.

Hope this is all answer to your question.
