977 power supply for EOS0610

[dirt101]

I'm in the market for a charger that can charge a 5s battery(using 977 now). I was wondering if the power supply from my 977 can put out enough power to supply the 610? It is rated at 13.5V and 10 amps.

It will be fine.

I used it before but wasn't satisfied so I bought a btter power supply. It will work but not at the level i wanted. Besides, I had money to burn at that time .

13.5vx10amps=135watts 80% efficiency puts that at 108 watts, so with that power supply you could only charge a 6s pack at 4.8 amps, to charge a 6s at 10 amps you need atleast a 250 watt power supply, 12volt 20amp is 240 watts(20x12)

BrianG also has a "power supply calculator" in his speed calculator application located as a sticky in the brushless forum. Thanks BrianG!

oh cool I never knew he had that.

I had planned to use it to charge a zippy 5000 5s. So I would be using about 93watts for a 5amp charge rate. Even if I had to back it down to 4 amps that would be alot better than the eos0606, and way better than my 977 which will only charge a 3s at 3 amps, and a 2s at 2.5amps.

I just based it on my 13.8v 8.5a ps that I use with my 1210i....

with that ps you could charge a 6s at 5amps, so yes it works, but you could not use your 1210 to charge a 12s at 10 amps, your max charge rate for 12s would be 2.5 amps, well below the rated capacity.

What about the power supply for a super brain 989 ? It should work or it's it the same one for the 977

It's different (150 watts)

It's 10 amps and 15 volts so any charger with a max input of 15 volts will be put into "error"

I ordered the 0610. I'm probably just going to keep on lower amps to try to keep my PS cool. I hope it works out for me.
