$55 1000W DC Power Supply

[Greywolf74]

Ever thought about buying a DC LiPo charger for the extra power, but didn't want to dump a boatload of money on a power supply? HERE are 1000W switching power supplies for $55 shipped. This is big enough to power most DC LiPo chargers on the market. You can get them in anything between 12V and 90V (although most chargers only go up to about 48V input).

P.S. Buy the highest output voltage your charger will accept. It's more efficient and reduces heat output which will make the fans run less also, which is good for reducing noise.

I need a 30v one if I were to grab one.

Here is a decent 30v supply if you want a 30v one. Select 30v, 1000w - 1fan and 110v input and it comes to $53.57 and $5.16 shipping.

I always just purchased a PS that was 5-6 volts over highest battery finish voltage I would be running on charger..just dint exceed the chargers max input voltage

I'm guessing it's pretty straight forward, but do you have any pictures or threads on wiring one of these up?

It's really simple. There will be a + and - output on the PSU. Just solder you up a cable with whatever connector plugs into your charger on one end and put some blade connectors on the other end to screw under the terminals on the PSU. I would solder the blade connectors on instead of crimping them.

Or you could also fabricate a terminal that has an XT60 or XT90 on it and connect it to those same terminals on the PSU. That way the whole thing would be more portable if that's what you need.

Yup. Exactly that

The hardest part is identifying the nuetral and live wires when connecting the AC input. Sometimes they are color coded and sometimes they are not. I would double check with a multimeter regardless. The live wire will be the one that shows ~120V when tested with a multimeter along with the ground. When you check the neutral wire against the ground the multimeter should read zero voltage or at least under 10V.
