I just want to confirm.
The information is only gone when the battery is removed right?
That was the way it worked when I tested.
Before : both 4.0V , Just finished then take a pic,
May be I use wrong slot to charge?
What do you mean POK?
whats wrong with the picture?
My guess would be that the charger is charging to more than 4.20 volt and triggers the protection in the battery.
Just finished. changed slot.
No display information , just finished charging.
I see, so the battery on the left isstill charging and the one on the right is finished?
This is an interesting charger but it has a few flaws that makes it imo a pass.
The nimh charging doesnt seem up to par, the defaut charging at 300mah is too low (it should be 500mah imo) and the fact that it stops displaying the info once a battery is full (weird).
It is fairly normal to start at the lowest current setting in chargers with multiple charge current. This charger can terminate a NiMH charge at low current, i.e. there is no problems with it.
And as I have already written: I did not have that problem.
POK based on wha HKJ said you might either have a defective charger or a bad battery.
Did the charger do the same thing with the other battery when it completed charging?
I din’t test more yet, maybe protect PCB batteries problem.
I've discovered this charger on your website HKJ, it seems to be very good for all batteries, perhaps the best critics you have written.
I was surprised with the unique button but finally, it seems that's not boring. Does it choice automatically the current for the chemistry? Or does it push the lower one? What is the interest to choice LiFePO4 for all slots?
Thank you HKJ, good job 
.
The single button is easy to use, but a bit slow when you want to select 1A charge current.
The charger do always start at the 300mA setting when powered on, changing batteries will not change current.
I am not sure what your question is.
For my 2nd question, I don't know very well LiFePO4 but I've thought they have not the maximum charge from the other Li-ion batteries, 4.1 V perhaps instead of 4.2 V?
I've seen the Skilhunt can't do any discharge or refresh 
. Nothing is perfect 
. Then I'm wondering if I buy it or no.
I don't understand why I don't receive notifications for response while it seems to be good in my dashboard 
.
LiFePO4 is 3.6 volt maximum when charging and will usual drop 0.1 to 0.2 volt when the charging stops.
Correct, it is not a analyzing charger.
Because BLF has just been moved to a new server and configuration is not finished yet [07-MAR-2016] Current status of BLF upgrade process
Ok for LiFePO4, that's why it's necessary to configure specifically the charger.
Have you in memory a 4 channel charger with dashboard display which is good and complete? I read your website regularly but I don't remember I've see one .
Ok for the forum. As I'm not easy in English, I don't come often on the forum and I only try to read the subjects which interest me.
Some questions HKJ, I can send you private messages but it can interest other guys : On your website, is it possible you write the date of the chargers tests on the main page? Thus we can find quickly the latest additions .
I've red a Li-ion battery doesn't be discharged under 3 ~3.1 V and charged above 4.2 V but on this test, you said that you wish the charger goes over 4.2 V. On Fasttech website, in batteries specifications, we can see batteries whose lower charge is 2.5 V and upper charge is 4.35 V. Are they more efficient or is it dangerous for the batteries?
Thank you .
Check the SkyRC MC3000, but it is rather expensive.
On my website everything is listen in chronological sequence, you can also look at the “Last additions” on the front page, it list all my reviews for about the last month (Again chronological).
The voltage some people says are only guidelines and often misleading. The low voltage from a LiIon battery is very depend on load, taking a battery out of the equipment and measuring with a DMM is unloaded voltage and can be more than 0.5 above loaded voltage, when battery is close to empty!
Most regular LiIon batteries has a upper limit of 4.20 volt, but some special types are made to handle higher voltage (4.30 volt and 4.35 volt). Before charging to these voltage you must now that the cell is designed for it!
I've begun to read the test of the SkyRC but I've stopped because it seems to be complex with a lot of possibilities and the test is very very long (as I said, I'm not easy in English). I try to maintain as well as possible my batteries but I have many other hobbies 
.
Ok for the chronology, I've noticed that the last ones are on top (but we don't know when you did them).
Sorry, can you explain? I don't understand.
Do you think that Fasttech specifications come from the manufacturer and thus are true? For example :
https://www.fasttech.com/products/1420/10001980/2204400-authentic-panasonic-ncr18650b-3-7v-3400mah
And I've seen that these batteries have the same reference but are not same :
https://www.fasttech.com/products/1420/10001980/2204400-authentic-panasonic-ncr18650b-3-7v-3400mah
https://www.fasttech.com/products/1420/10001980/2741006
It's a little disturbing.
You do not need a super smart analyzing charger to use batteries.
Battery charger reviews are done once a week (I wonder how long I can continue with that, before I run out of chargers).
When somebody says minimum safe voltage is 3.6 volt, they do not say how they measured that. When the battery is in a turned on flashlight 3.0 volt is safe (And often also lower values). When you take the cell out and measure it, the voltage may be 3.6 volt for the same battery that was 3.0 volt in the light.
In this article I measure some voltages with and without load: Battery charge percent
Fasttech just copy the specifications they get from their supplier and not all supplier are careful with the specifications. (Panasonic do not supply batteries directly to Fasttech or any other outlet for loose cells).
