Hyperion 720i power supply

If your power supply isn't giving enough power for the chargers you'll see a lower charge rate. If it's really underpowered you'll get an input voltage error. As for what Hyperion uses to test with it's likely an industrial power supply of sorts. This is a company that started in the RC plane side of the hobby so I highly doubt they are using a power supply that a racer would be using.

Hi Jason,
Maybe you can offer some advice on this.
I managed to get a used 1kw telco power supply that throws out -52V.
The +ve terminal is essentially at 0v and the -ve terminal at -52.
The potential difference should thus be +52V if I run the circuit in reverse.
Now I am not familiar with negative DC supplies of this power level, and documentation so far has been sketchy.
Is there anyway I can get this to safely run a pair of 720 or 0615 chargers in series?
Thanks,
DF

I just picked up one of these chargers and a 4S 5250 pack.
When using this charger connected to a car battery (deep cell battery I use just for at the track) what is the maximum charge rate I can use? I keep seeing that you can do 1C off a car battery, but can you do 2C safely?
