Now I'm trying to make sure I am calculating this right. If I am charging 4 4s 5000mah packs parallel it would be:

4s 20000mah 1c/20amp or 2c/40amp

4s pack 20amps x 16.8 = 336watts

This right? Just making sure I am thinking right and will have enough juice. Not sure on how long this charge would take?

So.... I should be ok with a 2c charge:

4s pack 40amps x 16.8 = 672watts

and get the charge time down closer to 30 minutes...

Thanks again for your help.....
