Not anything visible, but there may be something inside.
Mine,
When I charge left and right side slot of 26650s , no space for 18650s in middle slot like VC4
When charging is finished, information has gone , I can’t see information after charging is finished.
I did not have any problems with that, all the mAh was first written down after the charger had finished.
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 .
