I have watched mine do that. I think it is a test to see how the battery voltage holds up, and part of the CV charge cycle that hyperion has.

OK John, as i can understand, your's do that too???
Excuse me, because i'am french and i've little difficulty with english:oops:

I've e-mail Hyperion today and tell her this problem (maybe it's not a problem at all) and wait for reply.

On the Hyperion web site, they said to send email at this address:
info at hyperion-europe dot com.:oh:

I don't know what they want to mean, but i suppose is:
info@hyperion-europe.com ???????????

That email looks right.

Yes, my charger does that too.


And you are not french, you are canadian! :D

This is no malfunction of your charger. On the contrary. While supplying current to your battery the voltage rises. So to get a more precise voltage reading the charger stops charging for a few seconds to read the batterys "true" voltage. No worries ... this is normal. My Hyperion 1210i does that too.

Oufffffffffffffff!!!!!!!!!! A big thank, realy BIG THANK YOU

Now i'll can charge my li-po pack with peace of mind:yes:

I realy like this forum, we ask a question, and we have an immediate precise response.

Thank you RcMonster forum:party:

yes!! you're right, i'am Canadian, but first, i'am QUEBECERS

Just like I thought, it was a matter of understanding what the charger was doing.

OK right, i've charge a Venom 3600mAh Ni-Mh pack today, and charge it at 4Amps.
I've calculate that it was suppose to take 54 minuted to charge, BUT, the Hyperion 0610i drop the charge current to "0" at every minutes, during 5 secondes.
So if it was suppose to take 54 minutes, and drop the current for 5 sec every 60 secondes, so it will take 54 minutes X 5 secondes = 270 / 60 = 4.5 minutes more time to charge, so it will take 58.5 minutes.

And you know what??? The pack take exactly 58.5 minutes to charge and take exactly 3600 mAh.

Hyperion have program their charger to drop the charge current to "0" at every 60 secondes. Why??????????? I realy don't know, but it did it.

The only down side of this feature is that take lt=ittle more time to charge a pack.

odd. my 1210i came with a manual, and the piece of paper saying it came with no manual. :neutral:

Hyperion have program their charger to drop the charge current to "0" at every 60 secondes. Why???????????
Becouse its checking a voltage. Actualy my Great Planes Electrifly Triton made same.

OK thank you, so this confirm that my charger is OK!!

I just read the 0610I takes up to 28v input! That would make finding a suitable power supply much much easier.

Hmm, Hyperion must have changed the algorithm. My EOS7i does that 0v every minute thing only when charging NiMH in "auto" mode. Since the charger has no idea what capacity battery connected, it looks at how much the voltage falls when the charge current is removed. If the voltage falls just a little, it increases the charge current. If the voltage falls a lot, it reduces it. Larger capacity batteries will have less voltage change from charge to no-charge. It still uses delta peak for termination though.

But, when charging lipos or NiMH in a set mode, the charge current doesn't change unless I tell it to...

I've try every mode in NiMh and li-po, and always drop to "0"amps every minutes.
I've e-mail at MaxAmps and tell me that's normal, the charger is factory set to drop the current to "0" every minutes.

Must be a way for the charger to ensure the user doesn't select a charge rate that is unhealthy or dangerous for the cells being charged...
