When checking for battery capacity, Do I discharge to 3.7 or go lower? In discharge mode, it says to go to 2.8 for discharge capacity, but I thought a battery should not be taken below 3.7.
got mine yesterday. i can confirm that the v2 pcb has a larger (1000uf) capacitor, the v1 has 470uf. wondering if the larger capacitor is the solution henry xu mentioned for “improving” power supply issue hjk pointed out?
If you look at all my battery test, you will see that I go down to 2.8 volt.
Depending on battery the recommended minimum voltage is between 2.5 and 3.0 volt.
The 3.7 volt is not correct for a loaded battery.
That’s what I had suspected, but Henry’s response to the question of using a V2 power supply on a V1 board had me puzzled. While I didn’t think it would hurt, I wouldn’t expect any change in the behavior on a V1 charger unless they had also substantially increased the peak output current of the supply. Alas I cannot verify that, since the US adapter I got doesn’t have an LED, so there’s no way to observe the flickering HJK saw. However, it gives hope to V1 owners who may want to do a little improvement on their own. Depending on available space, it may even be possible to install larger 1500uF or 2000uF caps to mitigate the peak current issue more.

What does the display say when a process is finished?
Its been long wait I ordered mine about 2 weeks ago (05/02/2014 03:23:41 AM)
its still in the >pending< loop! What is it pending on?
Tracking Details >> RS114771xxxNL Not found .
Emailed Dora and haven’t received a reply!
Is there a special code to get an answer?
I’m assuming the orders are overwhelming and mine is lost!
What is the average ship time to the US? are there others with the same situation?
Thanks for listening

I don’t know about average, but my order was placed on 4/27, received shipment confirmation email on 4/29, but tracking didn’t really work until it hit NY on 5/6. Then it sat in NY for 3 days and didn’t move until just before the weekend, so I got it yesterday in tornado alley USA.

What tracking service did you use?
I’ve ordered two chargers, April 28th and May 3rd.
Tracking has just appeared for the first one but not yet for the second one.
In my case it usually takes 30 to 40 days to get things from China.
Now I can answer it myself, it says “full”. Since I was doing the ‘refresh’ cycle, I wasn’t sure it was still operating, or had finished, but it does seem to have improved my old 2500, blue Trustfires.
The real bad one is still being refreshed and is at 4.16v, and up to 108f at it’s hottest spot, the one that was just old and tired, came off at 4.20 and 2016mAh.
did we hit 200 orders yet? :bigsmile:
Yesterday morning it’s 176.
Ok, I’m noticing a peculiarity after running 3 test cycles with 2 different sets of 4 cells. In all of the results, there is always one pair of exactly matching capacities, down to the last digit. It’s still a bit premature to say there’s a problem, but this seems too much to be just a coindicence. I haven’t paid attention to which slots were matching until now, so I don’t know if it’s consistent, but on this last test it was slots 1 and 4. The weird random low voltage and low internal resistance readings also occurred with slots 1 and 4. I wonder if this is a sign of a problem with my charger or if others are seeing something similar?

Well! got a response from Gearbest “now there is a light at the end of the tunnel! to bad its a train!”
RS114771xxxNL its found now! Being sorted in the Netherlands Post
Ordered and paid for 05/02/2014 03:23:41 AM. Today is the 13th of May 2014
Thats 11 days and it hasn’t left the origin, I hope this is just slow updating.
07/05/2014 Thats July not June

Dora just informed me we already hit 193 orders as of this posting.
Once we reach the 200-unit mark:
1. All those first 200 buyers will be sent a coupon code of $2/unit bought.
2. A new coupon code will be posted to make the 201th buyer onwards have it for $39.
So will we be able to order another unit for $39 - our $2 credit (for being the first 200 buyers) = $37 total ???
I cannot answer this now. I’ll have to check with Dora first. I don’t know if two coupon codes can be used in one order.
Love the way all the people not waiting for HKJ’s review are making us patient people pay less!! Woohoo, good work boys!!!
fortunately gearbest holds the coupon alive that long time…
They’d be crazy not to. Once HKJ does his review and gives it the two thumbs up, ALOT more of these will be ordered.
