Hyperion Duo 3S 3300 x 2 charge time?

Hyperion Duo 3S 3300 x 2 charge time @ 1C @ 2C. Also, what is the math to figure this out?

I don't think there is any math necessary, if your chemistry is set to lipo,set the battery mah, and cell count/voltage correctly it will not charge at over 2C, so just jack it up till it stops.

Very easy to figure out!

Approx: 1 hour at 1C
Approx: 1/2 hour at 2C

1C = 3.3A on a 3300Mah battery therefore charging in approx. 1 hour.
2C = 6.6A on a 3300Mah battery therefore charging in approx. 1/2 hour.

Take into account, the time it needs to ramp up to full A at inital charge, and the time it needs to do the CV (constant voltage) part after doing the CC (constant current) part of the charge.

Hey Mavric.

Just to extend this a little, can you provide the math on how many amps/watts are consumed. I think this is one of those things that most people don't totally get(including me) so they get chargers capable of 2C, but can never actually charge at 2C due to the desired application, meaning the size of the battey.

For example I know you cant charge a 3s 5000 mah battery at 2c on a cellpro4... but its no problem on the Hyperion EOS, or DUO... again not totally sure why.

It's simply really...

For example:
1C is basically the Mah divided by 1000 to give Amp charge rate, so...
5000 Mah battery charged at 1C would be a 5 Amp charge rate, and since it's MilliAmpHour it would be approx. 1 hour to charge.

2C you would just simply double the 1C Amp input to give a 10 Amp charge rate.

Keep in mind that you have to alot for CC ramp up rate at the beginning of the charge (doesn't take long) and then the CV rate at the end to top off the pack to maintain it's 4.2V per cell.

Now if the charger can do a maximum of 10A output, you can charge 2 5000Mah packs at the same time at 1C or 1 pack at 2C,providing that the charger can handle the output watts as well.

That makes sense to me. How does wattage come into play? The Duo for example is 360watts, can this charge 2 6s 5000mah packs at 2c?

Always remember aballen that...

Watts = Volts x Amps

So...

4.2v (max volt per cell)
X
6 cells
X
5A (5000Mah pack)
=
4.2x6x5 = 126 Watts of power to charge at 1C

For 1(one) 5000Mah pack.

So you would need that times 2 for two packs = 252 Watts of power. Times again 2 for 2C = 504 Total Watts of power! You could factor in another say 20% - 25% for power supply effeciency therefore you would need a charger capable of 504 Watts of power and a power supply capable of at least 504x1.25 = 630 Watts!

Hope that helps.
