I was refering to BIG power supplies, like you need to power a 1000 watt charger. Here is one example of what I mean. 1000 watts for $450.

Surely there are better deals, but to improve charging time will take more than 350 watts. This setup I'm displaying is just one way to do it fairly cheap, and still use a charger that balances the packs when you want to.
Can you paralell several of the 350 watt power supplies? That might be a bit cheaper for 1000 watts of power to send to a nice charger.
Edit... Backtracked to the Goodrum thread AJ linked and answered my question. Yes you can paralell the power supplies. And a good pic too of how to wire it. Great to know that, but for the noobs, mabye a bit much to take on. Also I was misunderstanding about that charger, and assumed it was much higher wattage. One 550 watt hyperion has got to be better than two cheap 150 watt ones. So even if you could only feed it 350 watts, buying that charger is a good idea.
The main thing I wanted to show in this thread was how a noob could buy two affordable chargers, a fairly cheap power supply, and fairly quickly charge a 12s or 10 s lipo setup. All he has to do is unplug a series adapter on his pack, and plug in two chargers. Not so hard, really. The idea behind two charges is to charge both halves of the pack simultaneously. If you had a 15s pack, you might want three chargers, one for each 5s section if you chose the 5s packs. This particular cheapie turnigy charger actually does 8s, so you could run a 16s pack and charge each 8s section at 150 watts. Not bad for $120.
I hate to keep recomending get a ping to everybody, especially those who don't have any reason to carry 25 miles of range. But with the 2c ping, you have to. This just shows how easy charging lipo can be, and might make a guy decide 12s lipo would be just as good, if not way better than a ping if his ride is only 5-10 miles or so.
