Astro 109 does not go up to 8C rate
Hi folks,
My Astro 109 could only go up to 7.5 C rate. Does anyone have this problem? I'm charging my 5S4P 8000mah for the first time and just found this out.

I think you mean 7.5 amps. 7.5 C is 60 amps for an 8000mah battery and they certainly won't do that!
Mine are similar and the output depends on the source as well.
I'm waiting for the upgrade chip to come and will see if that has any effect on the power but I doubt it.

1C is 8amps for a 8000mah battery.

What you were asking (it is really sematics) is if an Astro charger can charge a battery at 7.5x's it's capacity (C).

The Astro 109's with a really strong power source might go to 8amps, but I have never gotten mine above 7.5amps.

It is not a problem charging an 8000mah pack at 7.5amps.
I do it all the time.

The problem would be charging say a 4000mah pack at 7.5amps.
Which would be almost 2C for that pack.
