I have 4 server psu that i arranged in series and combined the outputs. They each make 12v x 4 = 48v total. I took a kiln wire and clamped the 48v + and - and the kiln wire had 5 amps running through them (DC clamp meter). The psu have a indicator light at the end and it was green.
Now when i combine the 4 psu and put the leads against my lifepo4 battery which is like medium charge. It is 13s lifepo4 and measures 39v total. Basically the indicator lights go yellow and my clamp meter shows a current draw of 1/2 an amp... This is a problem!!!!
What is going on here.... I dont understand. Why cant i charge my batteries with the psu... The psu was fine putting out 250watts for the kiln wire at 48v, (48 x 5), yet it doesnt charge the battery and goes into shutdown mode!!!!
