I’m in for 1 unit, thanks!
UK/EU plug if possible
Im in for one unit with EU plug, Thank you
Today, Dora of Gearbest has confirmed that they have the updated firmware V2.0 version of the BT-C3100 and a sample will be sent to HKJ for a quick review. HKJ is already aware of this and will be waiting for it.
I am in for 1 unit. US plug if possible

I’m in for one if it can come with a UK plug.
I think the choices are only US and EU plugs. Perhaps you have to use an US/EU to UK plug, or a universal plug adaptor?

Quick look on Ebay shows adapters are cheap if it doesn’t come with one it’s not an issue
thanks tatasal
Nice info link there about the universal adapter for UK. In our place we also have that but ours is the universal (female) to US-type. Thanks
Hi everyone………
we arrived at fifty.
we can proceed to payment……yes…no…
Dora, my contact person in this gb, was on sick leave since Friday. Before going on sick leave Friday, she Skyped me that she will be reporting for work Monday, April 28th, HK-time. I will ask her on that date the coupon code to be used, and will be posted in this thread.
Funniest thing I read all day.
In for 2 pending HKJ review.
I would buy it if someone could confirm that there really is working internal switch to charge up to 4.35v. 
I found this pic! . It’s shame that this switch is really hard accessible.
I’m in for 1x, USA Plug. Hopefully HKJ’s testing shows a measurable improvement on some of his concerns.
I’m in for 2 units
No problem. With the firmware upgrade to V2.0, a complete set was instead sent.
Perhaps this link can answer your question: (excerpts below about the 4.35V)
http://www.mountainprophet.de/2014/03/15/preview-akkulader-opus-bt-c3100/
Since I always have some battery tests are missing for dampfakkus.de with 4.35V, I have tested quite extensively also to 4.35V mode of Opus. The batteries were reliably and accurately charged to the specified voltage 4.35V without any further problems, no matter in which slot and also at 4 * 1A full occupancy. As expected then showed the battery (of course only those that have been certified to this high charge voltage!) In the discharge curves corresponding results. The 4.35V mode is therefore not a marketing gimmick, but brings with suitable batteries a real added value in the form of better voltage curve and increased capacity over the entire duration of the discharge. In the handling of the Opus is anyway to worlds more comfortable than the Cotton Picker loader previously used by me.
LiFePo I have not tested because I do not have LiFePo batteries.
Already hit 50…how to proceed from here?
Please read post # 109.
Thanks
