The rating on the charger is:

10.5V~29V DC (20A, 150W max charge)
100V~240V AC (20A, 90W max charge)

Are you charging with the AC (wall plug)? If so your limit is 90watts = 3.66amp limit on a 6s lipo.

If you do have a power supply the manual indicates that a 13.5v+ power source is required to achieve the 150w max rating (anything less will limit the charge rate). I think there is a way to scroll down during charge to actually see the PS input voltage anything less then 13.5 will also yield a lower charge rate.

Watts charged at 1c required on 6s 5000mah is 4.1volts * 6cells * 5amp-hr = 123watts. Even after you resolve the supply issue I wouldn't expect moe then a 6amp charge out of that charger.

Wynn,
Yup,was the wall plug and thats why it wouldn't go past 2.XX amps.I should beable to get 7A MAX out of it and thats all I need..At 7A,should only take 25mins to charge.
I have never charged my packs more
than 1 1/2C because I want them to last a long time .
Heres a update video.If you or anyone else can,please tell me if I can get 13.5V out of this power supply?That would be nice (13.5V) and this would be a good setup for me ,thats if I can..

Based on the cell voltage and charge rate @ 2:31 you are only getting about 5.05a * 23.116v = 116watts out of the charger/ps combo. The reason for that is the input voltage is still lower then the required input voltage for the charger to charge at the 150watts. The other thing that happens to also hurt the charger output is the input voltage of the power supply at 11.928v @ 1:34 will drop (similar to a battery under load) as well once the charger pulls power from it and might be down to just over 11v further decreasing the watts the charger is able to output.

Sorry to say but probably need to look into another power supply with a higher output voltage and wattage to get to the 150watts of the charger.
