Got a chance to use this with a Hobby King Reaktor 300 watt unit. This power supply is very powerful. I kicked the charger up to 10 amps on a 3s battery. I was using a wire off my other charger that is only rated for 8 amps max, and the wire got hot, so I stopped and made a new wire that could handle 10 amps easily, scary. Anyway this is a good setup, and the price is definitely right. I got less than $100 in a 20 amp charger and power supply. I also give the Reaktor high marks as well.
