Hello there from Ecuador, SouthAmerica. I'm considering two chargers for purchase: the Liitokala Lii-600 and this one (DLYFULL A4) but only two guys did a review on the second.... I suggest you to be more conscise on showing the operation of the one you show. Besides, looks like the 4 small batteries you showed have a pretty high internal resistance, but I'm not familiar with that type of batteries (maybe that's normal), as I read that the lower the resistance the better are the batteries. If you post another video of this charger, try pushing the SLOT button to see if the display flashes once and keeps the screen on (I have seen this feature in the Lii-600). Good luck.
Hi there from Sweden and thank you for watching my video and your comment with suggestions! :) The four small batteries, I suppose you mean the 16340's - I have been using them in Arlo wireless cameras for 6 years or so I think, and their performance has decreased by now - the higher resistance is probably contributing to this as the cells have aged. As I said in the video, I will need to replace them soon I believe. The Liitokala Lii-600 looks very interesting with many features and good display! However, I couldn't find whether it will show the resistance on the display or not, and also if there is support for LiFePO4. As far as I can see it does not have support for 9V batteries either. These things are not a dealbreaker perhaps if you have another charger for that, but if you are looking for a single main charger for all of your needs, then having support for 9V and LiFePO4 might be of interest perhaps. I tried pushing the SLOT button like you said, but it seems that the DLYFULL A4 does not want to keep the display backlight on indefinitely. Thank you and have a nice day! /DrMBalmer P.S. I have a Nitecore D4 charger that I might have a look at in a future video
Hi again! It is strange, I got email notifications of your answer to my first answer to you, but when I check here in the video, I cannot see those new replies from you. Very odd, oh well, but I got them :) I am now very interested in the Lii-600, as you say that it should be able to handle LiFePO4 and show resistance as well! I checked some specifications on AliExpress previously and there they did not mention support for it, but the item description from all sellers is not always correct or complete I suppose. Temperature sensing and being able to control charge current up to 3A on all bays is also nice. Thanks for the info! I would like to find a charge that can charge 6 cells at once. Oftentimes nowadays I find that devices want 4.5V or so, so they take 3 cells. Charging two such sets is therefore a bit of a pain. There is a charger that is a bit interesting, but very expensive though: ISDT N8 It takes 8 cells and has a very nice color LCD display with lots of info on the charging. It can handle more exotic chemistries as well, but does not charge 9V it seems. "Only" up to 1.5A per channel. The search continues :)
@@DrMBalmer I must apologize for confusing you, I posted the reply but erased it because I mixed the info on the many chargers I checked. The Lii-600 does not handle LiFePO4 batteries (I though they did). I am glad, however, to share info I collected. I will get another look at the ISDT N8. The charging of the 9V batteries is just for household use, but if I go into assembling battery packs I need something to repair many 18650's at once and maybe 21700 as they support more mAh.
Aaah I see, no worries, thank you for letting me know :) Yes, please share if you find more interesting chargers. The ISDT N8 also comes in N16 and N24 models, having 16 and 24 charge slots - might be interesting if you plan on charging many cells at once for battery packs. You mentioned battery packs for solar energy in the comment that you deleted. In case you haven't already found him, I can suggest Julian Ilett's channel - he plays around a lot with solar if I recall correctly. Thanks for all the feedback! :)
Hi, Thank you stopping by and for your comment! The DLYFull A4 only has a Test(and discharge and refresh)-function on slot 4. However, in Test mode, you still seem to be able to choose the charge current at least. Hope this provides you some answers. Thank you and have a nice day! /DrMBalmer
@@margar2321 Hi there, It seems like the Dlyfull A4 charger has more or less been discontinued. I don't remember the price I paid several years ago, but I did find rebrands of what seems to be the same charger. Such as "EverActive uc-4200" which Google Shopping displayed when I searched for the DLYFull A4. Didn't find that one either on amazon, but perhaps there are other rebrands available in North America. Otherwise, check out the other similar chargers I have had a look at on my channel as well. The Nitecore UMS4 is a decent one (or the older D4 from the same brand). Let me know if you find some other rebrand of the A4 as well. Thank you and have a nice day! /DrMBalmer
Hi there, Which aspect are you specifically looking for when you say accurate; the accuracy of battery capacity measurement? It is hard to know since I cannot really know the true capacity of the batteries. I uploaded a new video today of another charger - the Nitecore UMS4. Have a look at it if you haven't - it is a more advanced charger.
@@lee99bay Aah I see, no I didn't, but maybe can check the battery voltage after charging cutoff and compare the chargers, it's a good point. Thank you, will look into it!
Hi there, Just wanted to mention that I have now had a first look at the cut-off accuracy of all the chargers I've reviewed. The video can be found here: th-cam.com/video/nPkzdLMtiaI/w-d-xo.html Have a nice watch (if you are still interested :) ) and day! /DrMBalmer

@@DrMBalmer if you like to have the best of the best buy skyrc mc3000.
*Is this DLYFull able to do a capacity test on all 4 bays/slots automatically with a charge/discharge/full-charge cycle?*
Hi,
Thank you stopping by and for your comment!
The DLYFull A4 only has a Test(and discharge and refresh)-function on slot 4. However, in Test mode, you still seem to be able to choose the charge current at least.
Hope this provides you some answers.
Thank you and have a nice day!

how much is this in America dollars i cant find it on Amazon is it available through Amazon maybe i need to look harder

How accurate is this charger?

It is hard to know since I cannot really know the true capacity of the batteries.
I uploaded a new video today of another charger - the Nitecore UMS4. Have a look at it if you haven't - it is a more advanced charger.
@@DrMBalmer I wonder did you check voltage after charging? Is this charger overvolting li-ion cells?
