Shame because I assumed this charger does all , clearly it does not and the manufacture clearly isn't interested in any updates, so buyers beware ! I fell for it as have a ISDT C4 Evo Smart Charger anyway , so didnt really need this
The MC3000 charges cells. It adjusts voltage and current, and controls the charging of a single cell. These 1.5V Lithium AA's are not cells, they have a cell inside but there is circuitry that surrounds it to take the Lithium 3V cell and regulate it to 1.5V. This circuitry also acts as the charger. So yes you are getting regulated voltage of these batteries, but you are also loosing efficiency because of the voltage converter, and its also a smaller cell inside because the circuit uses some space. So they have pluses but also big negatives. For example, a Lithium-ion battery doesn't like to be charged to 100% and stored, it should be charged to no more than 80% for long storage, where an Eneloop has no problem with a 100% charge and storage.Ha ha no that's why bought the skyrc , pretty annoyed as paid £100 for a charger that does no more than previous except c and d batteries , but support arn't interested in updating the firmware either. Yes as stated earlier need a 5v charge , but as I have a stand alone charger for these batteries that seems to be a dumb charger ( I maybe wrong ) I would expect the skyrc to charge them.
Did you ask ISDT if they can update the C4 Evo firmware to allow 5V charging? Maybe they are more willing?I ... have a ISDT C4 Evo Smart Charger
However, I don't claim that it isn't possible at all, just because I didn't quickly find an easy solution - who am I after all. And maybe it would even be possible for SkyRC to implement it in a manual way, perhaps as you suggested in the expert mode. But like most companies, they will probably do it only if they can expect significant sales from it - not because 1 customer (who already purchased his unit ) asked for it.I'm not surprized that the MC3000 can't recharge them.
I prob know more than you buddy ! also the circuit in an aa lithium is a step down converter as well as low/high voltage cut-off and I know it requires 5v to charge as its really a 14500 @ 3.7v . My bad for not checking the charger more thoroughly. To be honest I thought in expert mode you could change it to charge @ 5v, but you can't as it thinks its a 1.3v aa and you can't change that allWhat the hell did wus say wrong?? Get of your high horse mate. YOU clearly don't understand batterys and maybe shouldn't use the mc3000 in expert mode!
Well that says it all!My bad for not checking the charger more thoroughly.
Yes good point , I was merely stating that the manufacturer is not interested anyway. I could charge them manually but thought the charger that comes with them is a bit tackyYou're blaming the manufacturer for an assumption you made. That's not fair.
Also, as explained by wus, the kind of battery you have can have any of several ways of how it needs to be charged. It is impossible for the charger to know what method is needed for any specific kind of that battery.
There's a reason a charger is often included with this kind of batteries, because the charger is matched to the specific type of batteries.
Since a few days, the Sky MC3000 App (Android) that I use notifies me every time I start it that a new Firmware is available for download and should be installed in the charger. I now looked this up and saw that the new version - it is V1.15 - is dated 27.03.2020, i.e. it is over 2 years old.
I could not find a changelog or anything that describes the changes from V1.14. Did I overlook something? Do any of you know what changed?
It seems odd that a "new" firmware is offered only more than 2 years after its creation, does anyone here know why it is announced (by the app) only now? I'm using the MC3000 and the app since well over 2 years.
Google Play says tha app is V3.84 and was introduced on 17.12.2021. I'm always updating apps when new version become available....
The Krataxes are actually rebadged, or possibly cloned, Hixons, which in turn are rebadged or cloned by or from a number of other brands, you can find these scattered across Aliexpress with accompanying hit-and-miss quality control. I wouldn't want to use these with anything other than the vendor's charger which knows exactly what magic needs to be performed to safely charge them.Ah, Kratax... now it becomes clear.
I'm not surprized that the MC3000 can't recharge them. This sort of batteries, which use 3,7V LiIon cells internally and built-in step down converters to output 1.5V, use all sorts of different "tricks" to recharge the internal LiIon cell. Obviously, this needs 4.2 Volt, so this has to be provided to the cell, somehow bypassing the step down converter.
You can see this on some of the chargers for the batteries, you only plug the battery in on the + side to charge it, the - side is disconnected, so there's no way you're going to be able to charge it with any standard charger, firmware update or not.Some have micro USB connectors on the side, others an additional contact ring around the + button top, some require 4.2, others 4.5, again others even 5.0V on the + button.
Just so that no incomplete information remains here:Unless you really, really need 1.5V rather than 1.2V you're far better off with Eneloops. Even then, because they're running through a DC/DC converter they often have quite a bit of voltage drop at higher current draws, so you're not even beating an Eneloop there.
