If you need a power supply to charge your lipo and or li ion batteries. Use 3D printer power supply!
They come at 12V and or 25V variants with output of 10A to 30A! I just got mine today 12V 30A output for 30 euro equiv about 28 usd lol. Dirt cheap compared to Hobbyking charger that does the same but cost you about 90 usd ++ for the same wattage.
This is a link, but you can just google it! In overal they look the same and it could be cheaper in your country! http://www.dx.com/nl/p/input-ac-110v-220v-to-dc-12v-30a-360w-switching-power-supply-for-led-strip-388182?tc=EUR&gclid=Cj0KEQjwrte4BRD-oYi3y5_AhZ4BEiQAzIFxn8nYtfP6LMQLlkZ5Jo_PHrz2-6V2A2BJCQ2nbIXpwA8aAssT8P8HAQ#.VxYc1ZN95Yg
Additional benefit is that with this output you can also do VESC programming if you are not comfortable with lipo and or li ion connecting directly to your computer
