Also, one particular thing that I like a lot about Meanwell is that they actually specify their power supplies to work from DC. Usually 130 - 370 VDC. And it is a Taiwanese company, so they tend to supply higher quality than China. The SP-750 has a built-in PFC front end, not important for DC application but it tells you that when you happen to use it on AC, it will have a very good power factor and thus have minimal current draw, important if you need to share a line with other loads. http://www.meanwell.com/webapp/product/search.aspx?prod=sp-750 Regards,

I made that mistake once, won't do it again. I will only use name-brand equipment. In my EV's case, I'm using the Meanwell 750W 15V (SP-750-15). I've turned the voltage down to 13.5V, and it works very well. The previous one somehow had ingested some metal and literally blew up. Cheers!
