Meanwell 40a 600w 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 40 amps however they have a tiny voltage adjustment screw knob that is adjusted down to 14.6v output at 40 amps. So these are perfect for charging LifePo4 12v batteries at 40 amps. If you've looked for a 14.6v charger you will see how expensive they get. This one being 40 amps at this price is crazy low.

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. There is a white knob adjuster to the left of the black connectors. When you power 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 SE-600-15 power supply.
