Not home right now. If anyone can confirm that the end stage balancing time is indeed less please report back......thanks!

Actual balancing wont be faster, it was termination that was the problem.
Big parallel charges will always take time if balancing is needed as discussed previously in the other thread

It's a service firmware with two fixes

- When using EOS suite there is no overlap in commands that cause delay, if you uses temporary fix before of raising command delay you can now lower it back to 40-80 or so.

Note: IR reading is lower than 5.52 and earlier firmware, this is on purpose to be aligned a bit more with the rest of the chargers on the market.


Firmware is found on http://media.hyperion.hk/dn/pc/eosfw586.html
I don't necessarily want the IR to be more in line with the rest of the chargers on the market. What I do want is for the measured IR to be as close as possible to reality.

What I also want is the IR to be calculated and displayed while storage charging. In firmware 5.82 the IR is always zero while storage charging. Is this remedied in 5.86? Thanks.

There is multiple ways of measuring, so all are correct, depending on what view you have.
The method now is most closely to what is regarded as Cell IR

No, IR readings are only at charge or discharge in 5.86.
(you should always use same charge level for comparison of IR so you should only look at it at fully charged packs, and at same temperature as both state of charge and temp will greatly affect)

Good info. Thank you.

Mr Mel is correct. IR is a function of how you measure it. The closest to reality I know is the Wayne Giles ESR /IR meter which puts a significant load (16A) on the pack for long enough to get the stable DC discharge current. It is purpose designed for our LiPo packs, is very precise and is as close to the sorts of operating conditions we use to give a realistic IR reading.

The only charger that I have that does a similar test is the iCharger. Chargers like the Hyperions and FMA Powerlab measure IR by comparing the voltage during charge and the resting voltage when they turn off the charge current briefly. This is not the same conditions as a discharge but these chargers can give excellent results. My testing shows they become different as the cell IR gets high in old packs.

The new Hyperion firmware gives results that agree very closely with the ESR meter and iCharger and my judgment is that it is the best charger IR method I have seen (since the iCharger is accurate but limited to 1 mOhm resolution). The old firmware gave unrealistically high IR values and was not recommended by folks on the IR threads.

Atleast It's in one piece
Hi All

Can somebody advice me if updating my 720i v1 from firmware 4.7 to the latest version would give a worthwhile improvement.
I have just found somewhere that can supply the usb adapter and wiring harness which I guess may be a bit hard to get hold of now .
Also am I right in thinking I have to go to version 5 before loading the latest firmware.

Thanks Doffen I had seen one of those pages but what I was hoping for was for someone who had completed the upgrade to say if they thought there was a noticeable difference. I have just bought a new 720i v1 so now wonder if I should buy the usb and harness (which are a bit expensive )and update both or leave them as they are .

Max charge rate


So some lipos (Thunder power for example) can be charged at 12c. Is there a way to do this on my Hyperion? The limit seems to be 5c.

For those of you parallel charging with the 720, is it taking forever to balance charge? It is taking me twice as long now, kind of defeats the purpose.

Hyperion has "only" 300 ma balancing power, if your packs need balancing there is only so much it can do.

If you run the suite you can see how much goes time where etc
Make sure you run 5.86

You can fool the charger with size of packs to make whatever max C you will, but max wattage will rule over that anyway.

Plus imhop anything above 5-6 C has zero gain
