Will this power station sufficiently power an icharger 4010 duo to provide 10-15 amps per channel in the field? Im using a meanwell 24v supply to the charger.

How many cells per channel do you want to charge? That thing has only 300W if I got this right, so even with 100% efficiency in both power supply and charger (which does not exist), on 15A you'd be limited to 10V per channel to completely max that power station out. That's not even enough for 3S, for which a 4010 Duo is pretty much overkill...

He said he'd use a Meanwell 24V supply between that station and the charger...

4s on 1, 6s on the other.

So 10S on both channels combined. Simple math: no, you will not be able to charge these at 10, let alone 15A from that 300W station. Even at 100% efficiency (again, such a thing does not even exist) you'd need a peak power of 630W for 15A or 420W for 10A and that is going ot of your charger. You need more to get into the power supply to even get to that output. So got to round that up to at least 700W or 500W in real life, maybe even more. You could maybe charge these batteries with 5-6A with that power station.

Oops, give me an F for reading comprehension! Thanks for pointing that out, but why would he want two pieces of expensive equipment when a DC power supply will work?

the meanwell supply I mentioned is the dc supply. In the field I need to power that supply.

in the field I would only want to wait around for 20 minutes or so to charge or its not worth it. How would I figure out how much a 5s or 6s lipo powering the charger directly would provide for charging power for charging 10s combined? the continuous discharge rate of the lipo?

I do have a thunder power 5s 5000mah 70c ec5 to power the charger directly.

how bout this baby? should get me 10 amps per side which isnt bad.

Converter connected to a converter is a ot of losses. Also I would not trust capacity numbers like 78Ah in the 1st link. Why not using a simple car battery?

its a hassle and if you meant a stationary one, no way even more of a hassle luggin it around. ya the ah you speak of is way generous- marketing bull im sure

It's advertising 288Wh


So using Watts Law --> W = V x A


So


Ah = 288W / ?V


You didn't say capacity of your packs so for example let's say you have 4S packs at 16.8V each


288W / 16.8V = 17Ah or 17000Mah which will let you get close to 3 charge cycles if your packs aren't fully drained where 17000mAh/3 = 5667mAh


I recommend investing in a 12V AGM battery from AutoZone instead for around $50 which offers a 12V x 50Ah = 600Wh for more than double the capacity for half the price of the power bank linked in the OP

i did mention it. 4s and 6s packs same time. 10s combined. you can see above.
for mah --> 4s 6550 and 6s 5200

Still. 288Wh at the max voltage of 10S (which is 42V) leaves you with... (288/42) 6.85 Ah, or 6850 mAh - barely enough to fully charge your batteries just once before the power station is empty, maybe twice if you only got between storage and full, instead of from empty. (And by the way: Bill, 34Ah in your example comes down to 34000mAh, not 3400mAh. Still not really useful, but with that factor of 10 increase one could at least charge a couple of 2S batteries with it, instead of none).
