Will setting "balance trickle" ON will result in faster balancing?
Short answer no.

julez use this option I believe mostly because he does a lot of parallel charging at low charge rates as in over night charges.

Balance Trickle is covered in the Owner's Manual. The effect it has is to greatly increase the balancing time. Normal Balancing charge terminates at 1/10C , Fast 1/5C ,Slow 1/40C and Trickle adds a maintaince (float) charge to hold cells at 4.2 for addational soaking.

Note. Some LiPolys (mostly bargin brands) are so out of balance when received that it takes a very long time at a low charge rate to get them balanced. Most after being so charged and balanced a few times get better unless they have truely defective cells.

By chance
I've been testing a serial-parallel set of 12 V car bulbs (each bulb 55+60 W) with a half empty 3S lipo. However, it hasn't been possible with a fully charged 3S lipo.
Its really great ! Can you post some video ?

All my power supplies from various manufactuerers, even the one from my IBM laptop, have it in varying degrees.

From the above experience I now that this is somewhat depending on the unit, the sound will differ even between units of the same model. I'm thinking of asking for a replacement but I realize it is a draw of luck, will the new one be better or maybe even worse...?

In my case the sound is best described as "sparling" or "crackling". Maybe it will get better over time when the unit has been pushed and the electronics have been heated up and "burnt in" a few times?

Anyway I would appreciate if anyone with a P350 would share their experience. Does all P350 sound like this? A comment from Junsi would also appreciated. If the sound is not normal I really would like to now that. It's a very powerful device, don't want to burn down the house...

Generally speaking, all the power supply can make noise, but sounds low or loud. According to your description, if the noise wasn't caused by the fan, maybe caused by the transformers, for there exists gaps between wires and magnet steels during the process of making transformers. And the noise come into being as the oscillation caused by the vary of frequency. But it's normal as you mentioned the sound is not loud.

We can reduce the noise by spreading grease on the transformers to fill the gaps.



Not all P350 come with this noise, because we can not exclude we can make the grease completely and evenly. If the noise is too high to bear, you can replace another one from your supplier.


Sincerely
Junsi
This sound is NOT a buzzing (mosquito like) one normally found in transformers. It does not sound as it is caused by any component vibration caused by oscillations.

As I wrote before, it's sounds more like a computer hard drive moving its head or the crackling sound coming from a bonfire. I will use the power supply some more and see if it gets better, otherwise I guess I have to contact the reseller.

Then most likely the fan which you cam check by noting if it is quite when not running,if sounds change with its' speed and if sound stops when you stop the fan.

If you are DIY at all you can disasemble the PS and lubicate the fan and most likely it willbe much better. I lubucate the fans on all of my computers,power supplies,chargers etc. I use CLP Breakfree however many use 3 In One Oil and such.

The whining sounds with an identical frequency all the time come from some switching frequencies of components: these Power supplies are called "switching power supplies" for a reason.
The crackling comes from regulated circuits that change their power throughput all the time. some sensing circuits monitir the output voltage and load all the time, and adjust the power flow to the output all the time within a split second.

Block the fan with a small screw driver for a short time, and if the sound goes away, it was indeed the fan. If lubricating as Charles suggested does not work, get a "Sunon Maglev" fan with similar specs from eBay. These are the best.

It is not the fan, the sound is there even when the fan is not running. It must be from the regulating circuits that Julez are describing.

Well, then, if it annoys you too much, ask your seller for a new one. Perhaps, you can even ask him to test the new one for noise before shipping.

Today maybe not 20 but certainly higher than 10 A. And that smell... One of IRFs 3205 goes on the brink of explosion, I guess.
Don't you believe me?
And please, no remarks about my bulb stand

Not sure if I dare to ask this after all my questions about the power supply...

Anyway... I just saved settings for all my batteries and noticed one thing with my new 208B: the screen is not mounted totally flat against the casing, it is a little bit tilted towards me. Is this how it should be mounted, maybe it's done on purpose for easier readings (though I doubt it)? If not, does anybody know if it is mounted with double sided sticky tape? Just want to make sure it's tight and fully against the case so no dirt will get into the charger.

That doesn't sound right. The screen on my 208B is flat/parallel with the top of the case.
