Is it just me or does a balancer actually make a charger work harder near the end of a charge cycle?

I've noticed with my Triton and AF Blinky that the latter part of the charge cycle takes longer. I'm going to surmise that what's happening is that the Blinky is trying to keep the voltage down for all cells as the triton is trying to finish its cycle.

If I'm not mistaken the Triton charges up to about 12.64 volts (assuming a 3S pack). and my Blinky likes to balance the cells down to about 12.46.

Anyone else notice this? Thoughts?

I was fortunate to get a response from the gentlemen who wrote the firmware for the Blinky on this topic.

Yes they can. The blinky has what I think of as the panic mode. Where if
it thinks a cell is too high then it turns on the discharger for that cell
all the time. The idea is to delay as long as possible the puffing and
eventual destruction of the pack if the charger malfunctions. Well
chargers and the blinky dont always agree so we relaxed the panic mode to
4.25V per cell recently. Your blinky probably is lower than this.

What happens is the cells are probably all balanced and the charge voltage
exceeds the panic voltage so the blinky turns on all LED's all the time.
Since it is consuming 130ma per cell of the charge rather than going into
the cells the charge will take proportionatly longer to complete.

Yes, that sounds about right for the earlier model. You really shouldnt
need to balance every time you charge so you can probably just unplug the
blinky when all the LED's come on as the pack is almost certainly balanced
at that point.

triton charger

I'm a newby here and don't know how to start a new thread, or if I even need to, but I have a question concerning the Triton charger in particular. I've had this unit for 2 years, and it always works correctly with whatever type of battery I'm charging, ie. Lipo, Nicad, NiMH, etc, but even though I know I start with a completely discharged battery, the Triton never NEVER has indicated a charge approaching the capacity of the battery. If I charge my 1500 MA lipo, the indicator may show 450 ma of charge, a 2200 ma NiMH will get to 1000 ma etc. When I questioned Great Planes about this, the response was "you must be doing something wrong". Don't know what that may be. Does anyone else notice this trend or am I really doing something wrong?

Are you trying to use its Auto mode? I quickly gave up on all of its auto-sensing and have always set voltage (cell count), and mAh (capacity) manually.

Don't discharge your Li* cells below 3V per cell. For a 2S packs this is around 6V and for a 3S pack its around 9V. If you do you run a serious risk of damaging the packs. You should always be able to put back around 80-90% of the pack's rated capacity.

As far as NimH and NiCad, feel free to run 'em down as low as you can go. You should find that you can put back what they're rated at. If you can't, try cycling them a few times and if you find that you're always peaking at the same point then chances are they've been abused or cycled quite a few times.

Triton

Indeed I dont use the auto as well.

Re: NiMH

Once batt selection is done...push main menu button...and then use dial to go to the part where it reads "NiHM max charge input" and make sure it matches your batt max capacity. Whatever number is in there is what its going to output and stop.

Re: Lipo

You have described an overdischarged lipo, in that it will take in less amps despite the voltage reads correctly.

Charge at .7C (1amp) notice max amps taken (assuming you already consumed by use) which you indicate it to be 450mA.

Next use triton to discharge at 2.5A...whatever it reads at ends is a true indication of what battery has...if 450mA again...you confirmed my overdischarged conclusion....you indireclty killed battery by not using a BEC or improperly set.

Triton and battery charge.

I was told that if you do not discharge your lipos on the triton you will only charge up to what it needs.. If you have a 2100 battery and you only discharged 500mah during flight then the triton would only charge up to 1600 on the charge cycle and stop.. This is normal..

Allan

n2lry,

What?

Did you mean to said that the Triton will charge up and stop at 500ma and now your battery pack is top off at 2100?

It the charger puts back 1600ma, I think your pack will be over charge with 3200ma I know that not possible.

Yea something like that, sorry been on cold meds all week.. The triton will stop when the pack is charged not what the total pack is rated at...
