Want to build a field charging box..

[sevro]

I do like to parallel charge at home and have them permanently connected to both of my Hotas but I only do that when the batteries are really close together in charge. One thing about specs, these Hotas have high "balance current" which makes them charge most batteries in no more than 40-45 mins at 1c. Other chargers I've used are more like 1hr. The HGLRC parallel board is nice because it gives you xt60 and xt30 on the same board.

But for on the fly charging in the field not sure that parallel can help as much since you can't just throw one on in the middle of another charging. So multi channel chargers make sense to have on hand, but keep the balance current spec in mind on chargers that have more than 2 channels.

I guess it all depends on how long you plan on dwelling at a site, you could also fly 4 packs back to back but land early and use a smart discharger to bring them down to the same storage level. I've got the smaller idst discharger that I use on batteries that I didn't use or fully use on a given day.
