If you are just charging batteries for a 450 Heli, then this is WAY WAY over kill. He was charging two 6S batteries for his 700 helicopter in 8mins!! thats fast. Its just depends on where you are going to go in the hobby. You can make a similar system with less powerful and much less expensive chargers. Check out ProgressiveRC, they do some really cool charger units.

It will depend on your battery's C rating to how fast you can charge it. A battery that can take 2C charge rate (twice its Mahs) will take approx 20mins to charge. So if you have 4 or 5 batteries, you could pretty much fly all day long.
Charging off your car battery at 12V at 2C you would need a charger capable of 50W. If you wanted to charge more than one battery at the same time then you would need a higher Watt charger, say 200W. The ones in the video are 1350W each!!!!!! And are capable of charging a 12S pack in 8mins!!!!! Thats powerful :D

If you want a fast charge look at the gensAce batteries. Those suckers are 5C charge rate. I charge mine AT 5AMPS (charger max amps for 3s), If i could hit 7 or 8 amps that would be so cool.

The Gens Ace pack have been the go to pack for reliability at the best price. But i just heard that Hobbypartz as bumped the prices up by 20% which make them not such a good deal in relation to other brands. They will soon realise there mistake when sales drop.

Tony already pointed you to this thread... And it cost me a total of 50-55 bucks for power supply and 200 for the charger and all boards I needed so .. 250 or say 260 bucks ... But I need it to charge my 6s packs for my 700. 450 batteries... Now I charge 6 of them in 20 minutes at 2c..was it needed for my 450 3s 2200batteries ? No!
Accucel 50 w charger did a beautiful job for that ...

Fly safe!! :) have fun!
