once my driving improves and I am at the spot I would be able to take advantage of the high charge and discharge cycle I will be picking up one of these most likely.

My question is, will the power supply I have now be able to power this charger for a 40 amp charge and discharge?

Here are the specs of my current PS:

Input Voltage: 100~240V AC
Output Voltage: 12v~18v DC +-0.5V
Output Amps: 30A+-1A
Output Watts: 540W

Thanks guys
