There are duos that will do 25a per side so it isn't a stretch to assume 25a per 6s
That's a pretty safe assumption.
IMO duo chargers are the safer way for charging 2 packs VS parallel charging

Use what you have, I say. If you need to parallel, do it. But If you have a duo or two chargers use them instead of parallel to be able to monitor each cell. Other than that balance charging is fine. Safe too. Serial is where the sparks fly!

I want two chargers charging two packs each in parallel.
25 amps per charger. 12.5 amps per pack.

It's 1200+ watts. I understand that.

I literally never use the word literally right.

You will get just beneath that based on the math. Like you said the ps won't deliver. Might get 20a.

Still pretty good.

Even 20 might be an improvement.
Just thinking that a second PL6 is the cheapest way to get 40 amps+

A PL8 would do it with my supply but is very expensive as a second charger.
My power supply is also pretty expensive and don't want to "upgrade" it with some jury rigged server supplies that have no safety features or monitors of any kind.

What?!?!? Jury rigged is just fine. Now if you Jerry-rig it, then you gots da problems.

And my in-series server supplies are self monitoring. They will send out smoke signals (real ones), when something is wrong with them.

If you already have a charger and you buy a second you basically have better than a duo cuz you can send one in when it breaks and still be able to have limited use.

Looks like about 27-28 amps is all I get with 24V.

So if I run two chargers at 20-25 amps,I'll be way ahead.
And the PL6 chargers network so the PC software will control them like one big charger. Or just use the controls on one to control them both identically.

And I can always turn the expansion channel off and do 6S and 2S at the same time.

Or if I could get $125 out of this brand new PL6 I could get a PL8

a 1200 PS that no kidding does 1200 W
Like Acopian PS's or Tdk-lambda PS's?

http://www.acopian.com/

http://www.us.tdk-lambda.com

High end.....but you can call them, asking for tech support before buying.....and after you explain your specific application...and they'll help....

They'll know the details of "in-series" and "in-parallel" hook-ups.

FWIW

Thanks E but definitely out of my price range.lol...

My supply is good enough.
I just need a second charger or a more powerful one that can put out more amps with less volts.

This is what I'm using now.

Thanks E
NP....

Perhaps I didn't make myself clear.....

You can call them....1-800....and get their techs on the phone...and explain your specific issues.....you don't have to commit to buying....you're "choosing" which PS/PS's(hint) best suits your "business app"....

They'll gladly explain the details....and you will have spent nothing...to gain some detailed PS knowledge from "top of the line" PS manufacturers.

In addition, they have a bunch of free "on-line" documentation available....with PS manuals which include detailed wiring diagrams....and info with using 2 PS's....

So, check out the sites, and use the info....right?

To say it another way, these two companies(among others), effectively provide "free" PS tech support with regards to proper PS "hook-up" for our charging applications.

Plus, their on-line documentation lists "specs" that other PS manufacturers don't list.

I always try to make what I have work unless it is woefully under task. Like right now I could buy a 308 Duo based on my want list, but I have a perfectly operational 3010B which does what I need, which is fast charging in parallel. Sure a 308Duo would be nice, but what I have works.

I upgrade when what I've got is no longer usable. When the 3010B kicks the bucket, I'll buy whatever is the awesome charger du jour. By then the 308 might not even be "good" compared to newer releases.

I'm certain any phone call would have some sales push. Nothing is free.

Ssmith, If he means 25a split between any number of batteries I would think stating the number of batteries would be pointless from a PS consumption perspective. I just assumed he stated two because the information was pertinent.
Yep, I agree. I failed to pick up on that in the OP.

My bad. We still tight?

Probably, but one can get some good general info....and wiring diagrams and such from the tech documents.
