If this is true, i dont get why icharger even bothered with the 456duo. According to the specs, the 456 and 458 are basically identical charger, even down to max charge power/current. The only difference is 6s or 8s charging. At least with the 406 and 308, theres a huge difference in charging current (40A vs 30A) between the 2, but now they just have the same 45amp for both, I really dont see why anyone would buy the 456 over the 458.

Hadn't seen, or heard of, them until you posted those links. Looks "interesting"...but, I'd be willing to bet not as many will be sold when compared to the 308/406Duos. XT60 is probably the most commonly-used connector these days...but, for all the other connector types, XT60-to-??? charging cables cost more than banana plug charging cables. Using my battery collection as an example, I'd need 2 of each of XT90, EC2, EC3, EC5, Deans, QS8, and 7mm bullet (of which I'd need 2 reach of two different variants). As charging cables with 4mm banana connectors tend to cost $2-3 less (or more...and, that's per cable) than those with XT60 connectors, getting banana connector charging cables is a savings (for me) of at least $32-48. In other words, the 308Duo & 406Duo are, both, still the better value, and, thus, the 'smarter' choice.

The iCharger 456DUO & 458DUO are now available from multiple retailers...and, by available, I mean "in-stock", and not "pre-order"...however, I can find no information on Junsi's website. I have nothing negative to say about the iChargers, as I believe they are among the best chargers currently available...but, I don't believe the original company exists. In fact, in going to the Jun-Si Electronics website, the most recent product they have listed is the 308DUO.
Best I can tell, it appears that the original Jun-Si Electronics might have gone out of business around 2007-08...so, I suspect that some other company bought up the remains of Jun-Si, and have been building products under the Junsi name since then...or, to be more accurate, until 2021 at which point I believe that company (Hill RC) might have also gone out of business, with the assets being sold to another company. In looking at the bottom of my 406DUO (purchased 4-5 years ago), the very non-informative sticker has, in the lower-left corner, "www.hillrc.com" printed on the sticker...but, searching for that URL, it comes up with a Chinese-only website, showing the exact same products (again, 308DUO being the newest product), with the only difference being a 2011-2021 date at the bottom of the page. That's why I suspect Hill RC may have folded, with assets going to another company. If so, then that's who we have to (cough, cough) 'thank' for the products that have been released since 2021. That would, obviously, include the very "strange" release of two almost-identical products, as well as the (incomprehensible) reasoning for going with an unusual battery connector (XT90) for said chargers. Not that it really matters (as I won't be buying either of them...I'm perfectly happy with my 406DUO), but, I am curious as to who the 'actual' current manufacturer of Junsi chargers is. If anyone purchases either of these two chargers...and, if the bottom sticker has any info related to the actual manufacturer...please, post it here, as I'm guessing there might be some others interested in knowing this.

Hi, I have a question. I replaced the fets that were broken in my i-charger 406 DUO. Now I can charge with 20A but when I want to charge it at 40A they always break again. I have already measured the resistors and they are fine. does anyone know what's going wrong and how I fix it

I've used the 3306 FETs. Those are the ones recommended by Nick Adams on his Youtube repair videos.
Also possible that you're not getting a good thermal connection with the heat sink.
