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.
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.
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.
This was her last message before going for the weekend: (from Dora Wu of Gearbest)
