I don't think I like the new format for Docs/Video/News/Sell.
Found this there. No traffic for the posts.

Anyway this is a 1000WATT 14S charger from Thunder Power.
Couldn't find a price yet.

Thanks, TheWoodCrafter

I looked at it on their web site.
I see its input voltage is 12-36volts DC-- do they even make a 36volt power supply?
Is 36volt power supply required to get the max 30 amp charge rate?

I looked at that, it was not real clear.
The specs state the output AMPS but not at a voltage.
I would hope not.

You can get 36V from 3 server PS.

what i think would be nice is for thunder power to sell their own brand of power supply- other manufactures have their own COMPLETE set up.
I have done some reading using the pc power supplys; and jerry rigging them to work is not for me.

Well they work very well. You are missing out.

i hope it will take over 36v because if you put 2 power supplys together you get around 25.3v output.

I think most server PS have an adjustable output.

Just tune 3 of them back to 36V.
But that is the maximum input voltage before if frys
We still need to see what the input requirement is to get the rated output.

I hope it is 24V and not something stupid like 30V.

I have been using the 13.8v version of this PS for past 2-3 years and you can't beat the convenience or the price.

I called Thunder Power today and asked some questions.

The charger retails for $224.99
Available in January.

Output - You need 36V 40A input to get 1000W out at 14S

you get 756WATTS out for a 6S pack with 24V input.

So there you go, you can get it but you need special power to do it.
I think the best solution for that is 3 - 12V server PS wired in series.

I think I'll stay with my iCharger, I don't have any 14S packs anyway.

I know you can wire 3 12volt power supplies in a series to get 36volts.
But lets say you have one 24volt power supply and one 12volt power supply- Could these be wired in series to get 36volts?

I would think you could, yes.

I think you would need to un-ground the 12V PS on the DC side but I don't see why it wouldn't work.

I am just trying to learn and make sure what I end up buying will be future proof.
In the few months I have been thinking about electric they went from 24volt chargers now its up to 36volt chargers.

Next- 48volts? Then pretty soon will need a small nuclear power plant to run these chargers.

Is there anyone out there that has actually hooked up a 12v and 24v power supply in series.

The more I think about it the more I think it is no different than connecting a 3rd PS to 2 existing PS. Same thing.

It will work just fine.
But you need to disconnect the DC ground on the 12V PS.
Next- 48volts? Then pretty soon will need a small nuclear power plant to run these chargers.
Next, a little hydrogen power cell.

pretty soon we will need a flux capacitor with 10,000,000 gigawatts like in the movie back to the future!!!

Am I correct that this charger should be able to charge 2 6s 5000mah batteries at 20 amps? And the power source would need to be around 1260 watts?

I think I did the math correct?

Actually it will do 756WATTS with 24V input.

That is 30AMPS for 25.2V output.

So what do you think the max charge rate for a 12s 5000mAh battery would be if this charger has the full 32 volt input?

looking to add another charger.

Not sure..

32V is 2/3 of the way between 756(at 24V) and 1000 (at 36V).
That is about 917WATTS.
At 50.4V (12S) that is 18AMPS.
Maybe 3C rate (15AMPS)

When I called Thunder Power and talked to Mark, it seemed like he pulled out a publication or maybe a graph.
I asked about 6S and 14S rates. He spit out numbers.
Call them and ask him.

This charger is rated for up to 36volt input but how do you deal with haveing 3 HP DPS-600PB that put out 12.7 volts each? This would be 38.1 volts.

I looked inside the unit but did not see a voltage pot.

I think most of these server PS have a pot to adjust output.

I would look for the build thread on RC Groups to see if it is discussed.
