This is my power supply
https://www.competitionelectronics.c...mart&Itemid=80
13.8 VDC Current limit 23 amps
I charge my Thunder power 5000 at 3c =15 amps Charge and balance in 20min.
I can charge this pack at 17.2 amps which would be like 3.3C and be done in 17 min.
The thunder power pack can be charged at 5c. which is 25c which is 29.1 amps
This charger can charge at 40amps.
I need a stronger power supply to charge that high of a amps/C.
Something like this

1200W / 20V = 60A; DC24V output
So he is right you need a better charger and more powerful power supply
