5c lipo charging (playing with fire?)

[mtbd500]

My gens ace and thunder power batteries are 5000 mah (5 amp) and the label claims they can be charged at 5c
5 amp x 5c = 25 amp charge rates!
Has anyone ever charged the cells at this amperage and are there any commercially available chargers that can charge 20 to 30 amps that do not cost several hundred pounds?
A 5000 mah lipo could potentially be almost fully charged in approx 12 minutes! So the runtime outlasts the charge time!.

I have just been investigating and found this little baby, very tempting, must need a hell of a psu...

i have a skyrc 800 watt duo charger that can charge at 20 amps ether side
and a1200watt power supply Ive tried charging at 10 and 20 amp works just fine
also you don't need as big a power supply as you may think at 10 amps per side my power supply was show less than a 12 amp draw on it at 15 volts
to work out how many watts you need is a simple sum
volts 7.4 x amps 10 = 74 watts even at full voltage thats only 84watts
to charge 8.4 volts at 20 amps you would need a no more than a 270 watt power supply

My charger will do 20amps and my lipos will do 5C charging.

I tend to use 2C, I have been doing this for 2 years with no fires.

yeah as a side not i do usually only charge at 2 c

i have some 5c packs, still only charge at 1c. higher charge rates supposedly reduce the lifespan of the cells quite considerably
