charging life packs

[t-maxxracer32]

hey guys i bought one of those turnigy 4500 mah life packs and have yet to get a good run with it. Im charging it with my 12010i hooked up with the lba10 balancer and everytime i charge it (up to 95%) the charger only reads that it puts in maybe 50-300 mah each time.. ill run the pack for 2-3 minutes and it will die.. so ill charge it up and then it will get possibly 200-250 mah.. but the charger reads that it is 95% full.

am i doing something wrong? my basic settings..

A123 cell charge, 4.5 amps (tried 8 and it did the same thing..) 4500mah

i charge it at the a123 setting on my balancer.

do the life packs soak in so much mah so quickly that the charger wont recognize it? I wouldnt mind this, but my charger sais the pack is done and simply it is not.

im going to try charging it without the balancer and see what happens.

thanks for any input
