Hyperion EOS 1420i NET3 14s Balance Charger...

[fractal]

ok, got it. I just got 2 of these last week and the manual does not explain how to charge 2 6s packs in series.

[999zip999]

What O.k. so neg.is 1 to 6 and port A. And port B is 7 to 12 ending to pos. Just like their balance wires kit 1 red to pos. next 5 black to pos. and the last still black wire but to last neg cell. Sounds like an italain wire job in a car. Same wire 3 colors going thru the body.

Wesnewell there's 33 pages and when is the last time you heard from Gary.

33 pages of what????
Gary who?????
Don't have a clue what you are talking about.

[999zip999]

O.k. 32 pages of this thread to hunt for info. Gary Goodrum the guy how started this thread.

so i tried charging at 12s. everything is plugged in perfectly but i get a battery connection error. the input voltage is 13 volts. is it possible that its too low for 12s. the manual dosent say shit!!!! (tried charging eac 6s packs separately and it works)

[wesnewell]

Yes, that's too low for a 12s pack. It should be a minimum of 42V and that's lower than you should take it.
Oops, it's saying your input voltage is too low to charge at the rate you want to charge at. Either get a bigger power supply or drop charge amps rate lower.

it says battery connection error. as soon as it confirms 12s after the battery check, it stops and says "battery connection error"

Factal I have a 1420 and would like to hook up my 18s koion pack with 6s balance wires. And like to hook up 2-12s a123 packs with 6s balance wires. but I'm waiting for your answers. Damm flashing screens and can't find the one. If you know what i mean. Going to buy a 900w kingpower bmsbattery charger. And not a second 1420. You can charge with a 12v power supply it's just slower. I think you could go as high as 27v. for power supply. I just have a 12v 550w hook up and one sitting next to it just in case 24v1000w.

The "battery connection error" doesn't come up if your power supply is too small. If it charges your 6s packs fine it should charge your 12s packs too but just at half the amps. Remember these 1420i chargers were made for use largely by the RC guys who power their chargers with their 12v car batteries while they are out in the field flying their RC planes and helicopters.

I think something is still wrong with your connections when you series charge your two 6s packs. Can you take a pic and post it up?

The easiest way I can tell people to make the connections correct is to make sure pin #1 on port A (black wire) is connected to the same battery pack that also connects to the thick black (-) charge lead.

ok ill do that, but i can confirm that that is the way i plugged it. thanks for all the help!!!!

[Alan B]

All it take is for one balance lead to not make connection and you'll get this error. Replug everything.

[fractal]

ok i go it! in the menu it was still set at 6s. so i changed it to 12s and bingo! thanks everyone!

[999zip999]

There you go boy. Thanks Sacman, Alan B

[hillzofvalp]

Hyperion ought to release a new charger soon that competes with the power lab's power...

[999zip999]

I fill better with Sacman holding my hand. Thanks. Sucess 12s A123 20ah is charged on the hyperion. One more to go.

Hey now... me "holding your hand"... no no ... that's a pretty disturbing image (unless you are a hot young looking woman).

no but seriously... that Hyperion 1420 is an awsome charger and I'm glad you finally got thru charging 1 of your packs successfully with it. See it isn't so scary is it? You just needed to get comfortable navigating thru all the menus so you can see and monitor the individual cell voltages during the first few charge cycles. And after you've noticed the behavior of how it charges and balances you'll finally learn to trust it and not have to monitor it so closely.

So did you just charge or charge/balance that 1st pack. And did it play that little musical tune when it completed?

[mistercrash]

I use the Hyperion 1420i to balance charge the 14S16P battery I made using 18650V cells. The charger is set to charge each cells to 4.15V. All fourteen cells take charge pretty equally until they all get to the 4.12V mark. Then this one cell drops to 4.00V and the rest keep on going up until they all get to 4.14/4.15V and get the flashing little square beside them. The charger is now in balance mode and is trying to bring that one cell up equal to the others. It takes forever to do that and sometimes I just disconnect everything and stop the charging process.

When I stopped the charge today, the one cell showed 4.03V while all others were at 4.14/4.15V. I checked the voltage of that low cell with a Fluke 113 and it said 4.23V. Is my charger defective or is something wrong with that cell that makes the charger give false readings?

What did the other cells read with your Fluke meter?

[999zip999]

Mistercash I'm in the same boat.

[999zip999]

Sacman it's my first time so be easy. 500usd of A123 and.inside the garage ? First charge R/C 12s. Thanks again. The konion pack had a drift to 4.22v or more. So the 1420 was single cell charger till now. Konion pack charged with a ping 48v5a turned up tio 74.2v. Because it likes it. With balance wires ect.

My best guess is that there is additional resistance in the balance wires of that cell on your charging setup (most likely a pin connection on the JST plug). The additonal resistance could be fooling the charger into thinking that cell has a lower voltage than it actually has (hence when you take the charging leads away and test the cell with your Fluke meter test leads it reads higher voltage). I could be wrong so somebody with a good grasp of electronics theory please chime in and tell me if my reasoning is sound or not.

If you have another identical battery pack, charge it with the same setup and see if the same cell number gives you the same problem. If it does then I'd check the resistance of your balance leads going to that cell and compare it to the resistance of the adjacent balance leads. Also check that the pin/socket connection of the JST plugs are clean. Sometimes a thin crusty film of resin can prevent full contact connection and even read as a small additional resistance.

[999zip999]

Plus cell do have there own level some times good or bad and sometimes zero problems. But I monitor and use... Yea use It or look at it

[999zip999]

Maybe I have H.k. jst 6s balance ext cheapo's on the 74v kniona pack that has hyperion balance wires ? They plug in just fine. ?

[mistercrash]

All the other cells were at the 4.14V mark. I was hoping to find another solution to this but I have to take the battery out, open it and check that 16P string to see if a cell came loose. It is very likely that a bad connection is the problem since there are numerous connection points in that battery.

Thanks guys
