Can someone tell me what I need for a power supply to operate two ICharger-106B chargers at once. I am charging 6 cell 5000mh batts.

Re: Power Supply - Charger:
icharger 106B+: 250W output x 2 = 500W
Considering efficiency and to have a bit of a safety margin, let's assume 80% efficiency, now you need 625 W input, at a minimum.
To get full voltage, you need at least 13.5V input at the charger (not at the end of the wires) ... so let's aim for 15VDC input.
625W / 15 = 42 A
You need a power supply that can provide 42A continuously at 15VDC.... or you could get 2 x 21A power supplies...
PS ... dude, your website needs to come out of the 90's... have you considered using a CMS? www.drupal.org
