charger having trouble with big flightpower 5s

[rootar]

I use a Hyperion EOS0606i charger that has the built in balancer and yesterday at the track i wouldnt charge my flightpower 5s at 5amps like i had it programed for, it automatically charged it at only 2.5 amps no matter what, after looking at the specs on the charger it says it has a 50W output, im guessing im asking too much of my little charger. so i guess i know the problem but i cant find an affordable AC/DC charger that will handle what i need it to do......i can get a superbrain 989 but then wouldnt i be limited by the balancer? im needing a second charger due to having two packs for the gf's buggy, 3s lipo in the slash, and the big flightpower for my truggy, not enough time to keep everyone fully charged now witht he truggy in the mix.

im looking at chargers and balancers right now so if you have any suggestions let me know i need to get something ordered and have it here my friday.
