Ev-peak cq3 4x 100w and spectrum 30amp ps. Charges my 6s 5200mah 50c packs 4 at once takes just under an hour. This is my travel set up, but it really works great for me.

Understood, but just talking here to myself....

Last in my list of priorities is fast charging, the same goes to mobile phones. Such marketing sales pitch is one of the things that creates premature wear on the batteries. On my mobile phone I don't even use the fast charging box, I use a old type to the point the phone tells me to check connection as it may not charge quick enough.

I never charge at 1C, most times is half of the battery rating or less.

Maybe I am misunderstanding, X1 Pro is 180W while X2 on DC is 200W. Ok 16A on the X1 while the X2 is 10, I will never charge a battery not more than 10A.
Mine cost me $100 through Tower Hobbies a while back, so the 30 dollar difference not sure where is from.

And if am correct, the X1 Pro is DC only so you need the powerbox which is an extra 50 dollars or so. Way too much hassle to carry two extra boxes, two chargers, cables.

If that's all the faster you charge, probably worth looking into a parallel board to charge multiple packs at once. At least then you don't wait so long for many packs.

If what you want is 2 hour or 3 hour charging, that is fine. Still, do the math on how much wattage you need, add 20% for safety, and make sure you get enough. But .3c charging will be pretty low amps, even for big 6s packs.

I read a bit in this thread about the number of watts as being important however when I read the literature with chargers and the batteries, the focus is on amps for charging and the C rating for charging. So as someone without a lot of deep electrical understanding, talking about the number of what’s you need without mentioning amps doesn’t mean a lot to me as I don’t program the watts but I do the number of amps. And it is quite feasible that your amps will effectively limit the number of watts if that makes sense ie my 5000 mah battery can charge at 2c only (which is 10amps) even though the 400w charger is much more capable.....

I hope this makes sense

The math is easy, amps × volts = watts. Also, I recommend adding an extra 20% or so as a safety factor. It works out that for 5a charging, you need 25w per cell. So to charge a 2s, you need 50w. 4s needs 100w, 6s, 150w. If you want to charger at more amps, you need more wattage.

Also,
d it is quite feasible that your amps will effectively limit the number of watts if that makes sense ie my 5000 mah battery can charge at 2c only (which is 10amps)

That is backwards( sort of) If you max out our amps, but have watts left over, this is good. If you max out your watts, you will not be able to add amps.

Your statement is like saying the speed limit will limit the amount of HP your car uses. True, but the car still has the HP, it is just not using it .. if the charger runs out of watts before it makes the target amps, that would be like driving your car full throttle, and only going 45mph in a 65mph zone...

This is seriously the best explanation I have seen for why you shouldn't use a charger that doesn't have enough watts to charge your battery.
