Mine came today and I’m charging my first battery. So far it seems to work well. Right now the built in display reads 10mv lower than my Fluke 189. I’ll check the voltage when it terminates.
Not sure how helpful that would be since you’ll be monitoring incoming current at 5V instead of outgoing current to the cell at whatever voltage the cell is at a given point in the charging process. I guess one could calculate this out, based on some efficiency factor.
So true, but it’s the best I can do without putting the battery in series with a with my Fluke or current clamp while charging. I’ll rig it up when I have time.
Final battery voltage right after termination was 4.2246 Volts
Yup. Simple enough to do. I made a little tab from a piece of PCB and I soldered two short pieces of wire to it so that I can connect a DMM with aligator clips to it. Not pretty, but it works.
I have to order some circuit board material. It’s funny because in my early days I worked for a circuit board manufacturer. My company used to buy all sorts of grades from G10, FR4, teflon, etc in 4 x 8 feet sheets. I took home scraps back in the 70’s. I gave away some to my electronic buddies, the rest got lost in the shuffle after I moved. It kills me that I have to buy some now… lol
Charger DOES NOT DISPLAYS REAL TIME STATUS OF CURRENT FLOW via sense resistor voltage drop measurement and conversion (as you claimed previously in your answer).
It also has some issues, like a very dim top-off charge for li-ion cells (detrimental) and maybe too early current tapering. On top of this, seems like it's not very robust.
I checked the trickle charge after terminating at about 160-170 ma. When it terminated, there was no trickle charge for about 10 seconds. After that, I was getting a 6 milliamp reading for a few seconds, then zero maybe every 15 seconds, then it would repeat. I let this happen a few time before I removed the battery. Any thoughts?
BTW, I used my Fluke 189 in series with the battery.
Three ordered in the sale for $8.78 but only two received.
Package looked like it had been sat on but contents intact apart from crushed boxes and no sign of the third ever being shipped.
Tried to get my $2.92 back but requirement for documentation and video
evidence defeated me- life is too short.
I assume that this is part of their cunning plan.
Yeah, I mentioned elsewhere, maybe one of the GB threads, about taking a quick video of the Grand Unboxing, especially if anything looks suspicious. Ie, video yourself actually cutting any sealing tape, etc., for the first time, not just videoing the contents afterward (lest ye be accused of having the 3rd one in your pocket or something).
So then $8.78 for two pieces, isn't it cloggy? Still not a bad deal, though of course this is no excuse for deceptive practices.
When a deal looks like a steal, better watch out. Yesterday I ordered a Lii-100 in AliExpress via this advertisement, paid just 2.87€ (AliExpress Saver Shipping included, reachs home in two weeks or less) when all other sales were above 4€. Logged in a few hours ago last evening and, after checking out the removed listing, sent the seller a message to get confirmation that the sale was right and he didn't removed the listing because of price error. Just in case.
