Meanwell 20a 320w 12v Lifepo4 Power Supply - 13.5-18v

These power supplies were made for Lifepo4 12v charging. They were recovered from hospital computer carts in working condition and were charging the Valence 12.8v batteries. They output 15v at 20 amps however they have a tiny voltage adjustment screw knob that is adjusted down to 14.6v output at 20 amps. So these are perfect for charging LifePo4 12v batteries at 20 amps.

Input is universal. You can use any 3 prong standard plug and wire it directly into the input. This works from 100-240vac input and works on both 50hz and 60hz so this is completely universal. Blue knob adjuster you can see in the photo, When you put it up with AC power you can read the V- and V+ with a volt meter then use a small screw driver to turn that knob until your voltage output is exactly 14.6v or whatever voltage you want to go down to.

You can adjust these from 13.5-18v dc output so you can charge 4s lifepo4 and 4s lithium ion with this charger.

The unit is a Meanwell SP-320-15 power supply.
