I have 2x 720i super duo 3 chargers,which have faults in the ballancing/section.
my question is .Can these chargers be used ,unballanced ,to say 95%,and then ballanced with an seperate ballancer,and if so ,can anyone sugest a ballancer that can be relied upon.
thank you,any advise wellcome here,i cant afford another $900.au to replace these!

Is this happening on all packs or just one (could be the balance plug)?

Have you tried using a different balance board (the board could be bad)?

Good Luck,
Ball

thanks Ball,but
no its a common fault with these cheap chargers,but thats ok,
What i need to know is , is there a good cell ballancer @300ma disc ,to use seperately with any charger ? so i can still use the fast charge capabillity of the 720 super duo ?

Sorry to hear you are having problems with your charger. Have you contacted Hyperion for a fix?

I have exclusively used Hyperion chargers for nearly a decade and I have never heard anyone complain of any "common faults" with them. If anything, they are rock solid for everyone I have spoke with.

Yeah, I have 2 Hyperion EOS0720iNet chargers, and LOVE them. Only problem that I have ever had (which I have heard is common for them) is the fans will get noisy once in a while.

But never a problem with charging. Where did you get the idea that Hyperion are cheap chargers? It may not be the almighty (sarcasm) iCharger, but they are NOT cheap chargers.

4 out of 4 balancers are bad? Seems unlikely. Did they ever work? Positive the balancer is being hooked up correctly? Are you using a balance board or a direct connection? Hyperion uses a different setup than the JST-XH that have since become more common. I know the Duo3 I have came with two pairs of balance boards, a set for Hyperion/Polyquest and a set for JST-XH.

$300AU,which is what i payed for these is a cheap charger.$2,000US is an expensive unit !
there not serviceable ,electronics need servicing to be reliable !
they are complex ,and they fail !
BUT they do charge at a good rate !
Now all i need is a ballancer ,or 2 ,ie 1 for each port ime good to go again.

and both of these 720 duuo chargers are no good for ballancing ,for a start ,whenballance charging they stop to chech cells every 10 seconds ,takes to/long.the readings are unreliable and cells get over charged all the time .these chargers killed every battery i own before i woke up/to it.the resistance readings are no good they stay the same untill the power is disconected ,even with no batt fitted the readings stay the same .
aass wwell as faalse readings .ive conected batts to both chargers without the unit being powered.maby thet wrect them
also,i think the ballance conections areno good ,if you give a wiggle all values change ,and some chanels allways give bad readings for the same numbered cell,regardless of battery.

Its only the 720 super dou that has this problem,and i think the newer ones have been fixed,the ballance conections fail something about the soldering ,everyone i know who got one here got same failure !
And as far as i know Hyperion dont service anything

What?? $300 AUD is $213 USD, not cheap considering there are pretty good $60 chargers out there. $2000 USD could get you an entire race package new from a hobby store.

You continue to say how unreliable they are yet you seem to be the only one having problems with them. The fact that you are having the same problem with 2 different chargers leads me to believe that you caused the problem by doing something wrong. Maybe hooking them up not powered or like someone else said, using the wrong balance boards.

They are serviceable. They are complex because they have a lot of features, that make them customizable to do what you want them to do. If that is too much for you maybe the Traxxas iD system would be better suited to you. Balancing a battery properly takes time, so checking the rate often is a good thing. What exactly do you mean by over charging? Being that the menu is so confusing maybe you made a mistake with the setting causing them to over charge your batteries?

I have personally never even heard of a $2,000 RC charger. Maybe complete with case, fans, power supplies, etc.

Honestly, I have a hard time believing this. Either your settings are messed, or a software update was done incorrectly, or your chargers are broken. This is not normal behavior for a Hyperion charger.

It shouldn't have, but I guess anything can happen.


Is it the balance board or the actual connector? Have you tried a new balance board or balance plug?


Did you buy these chargers new or used?

oh yea ,a decade hey ,thats 10 years yea?and how many hyperion chargers have you gone through ?the first gen of 720 superduo had faulty ballance connections !and hyperion dont fix/service in australia.waranty is no good .

I charger cheap to,didnt say i had a problem,charger is worn out thats all.
i just bwant to use the fast charge 50amp of my old hyperion, and ballance with something cheaper.

thanks 4 mile crazy,yes youre rite,,,, ,ime too stupid for these highly sefisticated (notice i cant even spell it)CHARGERS ,i connected batterys to the chargers and they wern't powered!1
bloody mistake ,very easy to do ,and bingo chargers are toast.
If theyr servicable then where in Aus ?i can garanty you that the cost of freight will not be worthwile to fix .ime in north queensland ,no service here!

ALL I WANT is a bloody good ballancer ,@300mh to1000mh ,like the power lab .

It's not hapening on any packs,i hanent found the right ballancer yet ,just making enquiries,
i need a good ballaqncer is all.

yes new two years ago .now stop wasting my time .Ime not interested in Hyperion ,ile never buy another,
ijust need a ballancer,a good one thats all!!!!!!!!
