36 volts into dual powerlab 6
I am putting together a charging case. I have 3 power supplies in series for 36, volts. The charger I am considering is the Dual Powerlab 6 touch. The input spec for this charger is 32 volts.... What kinda oddball crap is that...
Anyways question is is the extra 4v gonna fry the charger?.
I dont WANT to break it!

I'm not ignoring you. I don't know the answer.

32V is an odd number. I just check my iCharger spec. Max input voltage is 50v which would work well with a 4 X 12 (48V) volt power supply.

I'm only speculating, but my guess is you will get an over volt message or "input voltage" message and you won't be able to proceed until it's fixed. I've seen that before on other chargers when I plug them in my power supply set to output power for the 4010Duo and the charger will only accept less. But again, I'm only guessing.

Or it may damage the charger so it would be risky plugging it in to a voltage source over the rating of the charger

My Icharger 308duo has a max input of 30v. Kind of weird too so I just run it off of 24v with the only compromise being that I cannot hit max rated output. So unless you need to charge at the max rated wattage, you'll be fine with 24v.

On a side note, I also have the PL8Dual as my home charging setup and run 4 - 12v series power supplies. Each one outputs about 12.2v so the total stackup is almost 49v. I haven't had a problem or gotten an alarm with that. I figure 1v on something that takes almost 50v is only 2% off. Nothing rated at 48v will blow up at 48.1v.
But running 36v is off by 12%... that's pretty significant.

I may go with the Dual powerlab 8 touch when it comes off of back order in October'18...
In fact the thought has occurred to me that this may be a reason for which powerlab has made it an oddball input voltage max for the less expensive dual 6 touch.
Make it easy for the flagship product to reach full potential on power supply setups people commonly have. Make it slightly more difficult to do the same on or less expensive machines

For sure!!!

Always take this into account... More voltage, less amps for the Same amount of delivery power... So, Charger happier.

Of course, don't overestimate your charger.
Follow the instruction manual... Always!

Tweaking things are expensive...

With most Power Supply .. we are able to adjust the voltage.

I always recommend using a single power supply of the desired voltage rather than multiple power supplies in series.

That general rule is correct but...
More voltage, running power supplies in series, means less current for the Same delivery power output.
power supply will work lower in temperature.

A Good reason if your charge parameters compromise more than 70% of the power capacity for your charger.

Obviously, if you don't charge your LIPO at 3C or more, a single power supply, you will need.

Nothing oddball about it. It was designed around the max voltages of the electronic components selected for the design. Most industrial power supplies have an adjustable voltage output. Server supplies are an exception since they're designed to run at a specific voltage.

I've been running my Dual PowerLab 8x2 for years on 48v w/o issue. I would highly recommend not running any PowerLab charger at a voltage higher than its maximum specified input voltage.
