Can anyone comment on how this deal varies from the version listed as a BC3100 in this previous deal for $45? Presumably they either will both have / not have the oscillation problems (although since it results only in minor li-ion undercharging, it’s probably not a big deal anyway)?: Deal alerts for Banggood.com - BTU Shocker, SolarStorm, Olight, XinTD...
Well, I guess I’m in for one as well, since I really prefer proper slots over the mess of wires & magnets with a hobby charger. If I’m understanding this right, it looks like they addressed the power spike issue within the charger itself rather than using a higher current power supply. I wonder if we can add an even bigger capacitor to “improve” it more? What will it do to the life expectancy of the power supply by drawing over twice the rated current, even over such short time periods?

welcome to BLF
I cross-posted this deal over at SlickDeals. If any of you are also SD members, go thumbs up it & help answer people’s questions and maybe we can get a few more towards the 50 unit goal.
Hi BLF,
Is this group buy for US version only, or EU will be down to $41 either?

Opus BT-C3100 LI-ion NiCd NiMh LCD Smart Intelligent Battery Charger with EU Adapter - Black
I think it comes with an EU like in most photos, with a US adapter.

Link in the title goes to “Opus BT-C3100 LI-ion NiCd NiMh LCD Smart Intelligent Battery Charger with US Adapter - Black”
Gearbest has EU version either but it is more expensive now ($56.99 vs. $59.14), and it’s unclear whether special price is coming for both versions of just US.
:~ Sorry for misunderstanding. You mean it is EU or US?
jealous57, thanks. Now it’s clear 
I am in. 1 pc.

Same Group Buy for both configurations
If HKJ gives this the nod (after his second review) over the i4 I will one
done and done
Thanks
I’ll take one if HKJ can confirm the fixes. Emailed Dora.
That would be somewhat disappointing, as those adapters usually make the plugs huge and are sometimes loose fitting.

I’m in for 1
If the problem is solved, I am also in for 1. Will wait on HKJ to test.
The improved version will show 2.0 after power up for 2 second and then make full segment display turned on. This is the way to tell the difference between HKJ’s first reviewed version which has no version number displayed after power up. In future, if we make any improvement, we will have this version number updated reflecting the change.
