Engineer Lii-260(LiitoKala) the smartest li-ion charger in a world?

HLK are any of the new chargers capable of charging D batteries?

I just bought 12 Tenergy Ds and don’t have a charger that will charge them.

I do not have any D capable charges in queue for review (One of the Soshine does C cell, it is not perfect, but useable).

The only working D cell charger I remember to have tested is the BT-C2000.

If I wanted to buy a D cell charger that could charge many cells, I would look for a Maha C808M, but it is a bit on the expensive side (I have never tested it, but my general experience from using Maha is good).

It would be very nice if it could charge all possible batteries + 4,35 to 4,2 V selection and of course for less than 20$ if possible :)

Me also... I am waiting for pro review of this little charger. But even now I trust him and for first time I am leaving charger unattended :) and it is doing everything what I need...

I just say "liito kala charge!" And he charges, and then I say "liito kala measure capacity!" And he does all that while I am gone on beer ;)

I have that problem too!

That is much more dangerous than playing with LiIon batteries

Well it is good for nerves but bad for body especially for belly :)

And sometimes doctors recommends warm beer for kidney stones(seriously I am not kidding here)

When you move around and depending on how you move around it can also be very bad for other parts of the body, especially after a large dose.

And the next morning can be bad for the head and stomach .

But if you can handle it responsible, the risk is minimal (Like LiIon)

Exactly good beer is like good li-ion battery :)

I might need to clarify something lost in translation. “Gone on beer” could be interpreted in English, Australian English anyway, as well and truly drunk. While I assume the meaning you intended was simply free of concern over the battery charging and having a beer?

But I agree with all of it. Except the charger, I have no idea until I see a review with charts and stuff. No hints yet HJK?

And you said you had an accident while testing it, what kind of accident?

I understood it without any amount specification, i.e. it could be 1 beer or 20 beers.

It looks good until now.

I simulated a battery with too high voltage, when checking the voltage readout (At least I believe that was the reason). The discharge function is gone and I believe that this problem might have spoiled the resistance measurement.

Ooops!

I am not into English language since it is not my mother tongue :). But I have thought about that as drinking a beer in a bar while Charger does all the rest...

LiitoKala R.I.P... How much high voltage? So he does not have over current protection?

Exactly. Accidents happens, even if I try to be careful. Luckily the charger was not that expensive, I get much more depressed when I blow something to a couple of 100 dollars (This happens very seldom) .

Probably around 4.5 volt, when turning the knot on the power supply it is very easy to turn a bit to high. This does not have anything with over current protection to do, but the charger is simply not designed to handle more voltage than a LiIon battery gives.

Poor little fella... I really like him...

If I had disliked the little fella, I would not have ordered a new one, but only published my current results.

But I believe it is worth doing a good job on him.

That is very promising coming from you. :slight_smile:

I’m just worried about heat. It claims it can discharge two cells at one amp each, that’s going to generate some heat, yet there’s no fan. For a $25 charger I’m not above buying a small CPU fan and cutting it into the body and circuitry, but it would be nice to see it there.

I do believe the discharge current is "only" 0.5A, but it gets fairly warm doing that.

HKJ,

Charger has selectable discharge current modes. 500/1000mah (it really charges/discharges faster than on 500mah mode, but however I can not check does it really charges at that current, you will have to do that :) ).

I will quote myself:

"How does discharging/capacity testing works? Very simple… Once you fully charged your battery(4,2V) put it in desired channel and wait few seconds… When 500mah charge blinking display appears press and hold mode button for 3-4 seconds, and then it will go to “discharge 500mah blinking mode” in which with one more click you can turn to "1000mah discharge mode".

It will start discharging in selected current mode, and it will give you real time readings. The most interesting part here is when it discharges battery it will instantly start charging process again. What that means? That means that you can put freshly charged battery in and charger will discharge/test cell capacity and it will automatically charge it. So put your 18650 battery in discharge mode and go to sleep and in the morning you will have freshly charged battery with tested capacity."

I am charging in one channel at 1 A of current while discharging/testing at same current in other one, and heat dissipation is good... It is warm but it is not hot... In fact for comparison it runs much cooler than sanyo nimh charger(frying hot when charging nimh), and lot of generic li-ion budget chargers that have fully enclosed housing without any air circulation so heat is trapped in them while on liitokala heat is escaping through that little holes on its body. So on 500mah charging/discharging it should be even less warmer than on 1A.

Heat happens but it circulates through that little holes from the bottom and upper side of charger.

So you fried something in your charger. It can not be hot... It can only be warm...

I will report in this thread if anything bad happens(30 pcs of panasonic ncr18650pf is coming these days so that will be real test for it) but with my liitokala so far so good...

From the manual I got the impression that it is the charge current you select, also when in discharge mode.

When I get the new copy I will verify that.
