what is this thread weally about?
4.35v charger?
how about xtar
This is the slowest order I have ever had from a US supplier / US warehouse!
Ordered 1/3/2014
Picked up by DHL 1/5/2014
Switched from DHL to Postal Service in Kentucky 1/7/2014
Sort facility in Philadelphia 1/16/2014
No updates since!
Ugh!

I do have some of the new 4.35v XTAR chargers on order, but this is still the best budget option, in my opinion. I think that the 4.35v volt cells are going to be the best thing for amp single-cell XM-L2 / XP-G2 lights with our current drivers. I need to do some testing with a 5.8/6.0 amp XM-L2 vs. the current leaders: the 20R & Pana PF. If I can get output like the 20R but runtime like the PF then I'll be happy. I think these will do it. I have two of the 4.35v YiboYuan chargers up on the website.
Yeah, I thought the Xtar 4.35v chargers were a bit expensive for my taste. I'd love to see results of your testing if you get to it.
-Garry
Since what we're dealing with is a high forward voltage requirement and not a huge amp draw, I think these will be awesome. I am going to try them on my BTU Shocker mod as well vs. the 20R (if I ever get around to finishing it!!!)
I also like the lg most, but have in mind that they are only rated for 4.35A maximum discharge.
Well it arrived today! However, I did NOT receive what was pictured on Tmart's website! (Does this surprise you?) Here is what I received:
It's not a "YiboYuan" branded charger, and it's only rated 350mA! Doesn't look so great inside, but I'm no electronics guru so I need some of you to chime in and tell me if these internals look acceptable or not. In that last photo, the AC prongs are in the top center with black wires attached, and the output wires are going off the photo on the right side. I have not powered it up or anything. So does this look usable? Or does it look unsafe or untrustworthy?
-Garry
Hmm, this could maybe be a YiboYuan charger. The box is identical but without the YiboYuan name on it (comparing to pics on DX).
-Garry
Garry,
This is the same one I have and it works well, just charges slow. Terminates at 4.35 like a champ.
I bring up the cells to 4.20 on another charger, then top off with this one.
Runs cool, no problems.
HTH

I have yiboyuan universal version, and it is very good.
I can charge any cell phone battery, it is adjustable.
I got it from DX, which is the same one on this link
It do not look great, but it might be usable.
Has CY1 a couple of approval marks on it? If not, I would be very careful with using it.
Interesting idea. I wonder why it's all old-school, through-hole components. I took a gamble and ordered one from Tmart. Thanks for the report Garry.
I've found some YiboYuan AC-10 chargers on EBay which are 600mA rated. Think I'll order two of those.
-Garry
Probably a stupid question, but which battery contact is positive and which is negative?
Check them with a meter. I haven't used mine.
-Garry
Got it, thanks! Positive is on the left and negative is on the right. (On mine at least.) I can’t believe I didn’t think of that! :8)
Well today I received my two new YiboYuan chargers I ordered on Ebay (see post#26 above). Came from a US Warehouse, not extremely fast, but not terribly slow either (faster than Tmart!). I did in fact receive YiboYuan chargers, HOWEVER I received two model AC-11's and not AC-10 (it was only the photos in the Ebay listing that showed AC-10, it wasn't stated anywhere in the listing). I don't think this is a big deal though since I can't spot any difference between an AC-10 and an AC-11. Both are 4.35v @ 600mA charge rate with a USB output as well.
In any case, here are some pics:
The internals don't look as sophisticated as the first charger. My first question is, where is the AC -> DC circuitry (i.e. the 4 way bridge rectifier circuit)? So how does this one look? Does it look safe?
-Garry
No response?
-Garry
Cheap equipment sometimes only uses one diode not a bridge rectifier.
It does not look safe for 230VAC.
