New version 2.1 Opus BT-C3100 "Dreamcharger" GROUP BUY @ $ 45, shipped via China Post
Since I posted about version 2.0 I figure I'll do the same about version 2.1! I have the 2.0 and absolutely love it I am probably going to purchase the new version as well. If you need a good charger then seriously consider this.

gearbest said:Hi BLF folks,
Here is some good news for all Opus charger fans
First, the breaking news is the new 2.1 version Opus BT-C3100 is available now :

Opus supports us to run this campaign at $45 for the first publish, only 70pcs for EU and 30pcs for US, *It can be available for ordering right now*, the coupon code is: *BTC3100*. *Barring any unforeseen circumstances, the 2.1 version will be shipped starting Aug. 27*.

coupon code is: BTC3100
Price: $45
The improvements of the 2.1 version provided by Henry Xu, the engineer of this dream charger:
1. voltage update rate is 30s instead of 60s.
2. charging voltage is regulated to 4.7v instead of 5.0v, thus loading on power adapter when batteries are flat is less. 5.0v charging voltage has problem in regulating the correct current level due to this over loading current on power adapter, which lead to Panasonic brand Li-ion batteries showed wrong charging capacity value(+25%). With 4.7v charging voltage, the load on power adapter is greatly reduced and thus can make all types of batteries are charged properly.
3. 4.35v charging time can be very long because charging current is regulated in entering the CV stage at 4.12v, which is same as 4.2v type. Now 4.35v charging algorithm is changed to 4.27v.
4. Better safety feature: PCB temperature was used to in controling fan on/off only with 2.0v, now this function is enhenced so that temperature is monitored for entering thermal shutdown mode when excessive high temperautre is reached. It is especially helpful when fan is not running and which can lead to plastic melt down happening.
5. new fan cover make better protection for cooling fan.
Besides, we do a simple video to show the different package for the 2.1 version, more details :
And a complete review will be public by *HJK* in the following days

2.0 or 2.1, which one will you pick?
This was from when I posted version 2.0
I just wanted to pass the news to those who don't venture on to BLF. This seems like a very nice charger if a couple things were fixed in the update. HKJ is being sent the new version to do testing on and then will announce the results. Most people are waiting for this new to opt in 100%.
