multiply the capacity by the charge rate.

5500mAh with 2C charge rate = 11A

That is the max though. I don't charge my batteries that high.

so i have a pack that has a 4c charge rating with 3000mah which would be 12 amps, right? so i can safely charge my pack at 6 amps? or would that be a bad idea?

6 amps should be safe if your charger and power supply can go that high....most chargers are 5 amps max...and I have seen many 10 amp chargers turn down or have issues due to low input from power supply charging at that level.

I usually just charge all my batteries at 2 amps.....if I am at the track and have to rush I will go up to 4 amps

all my packs are 4000mah 25c or higher so they could charge much higher..... but I still just use 2 amps
