Hi again!
As promised, I have updated the review with more info.
After about a week "playing" with it, more or less I know all the functions.
I have had my B6 clone for quite a while now and have been very happy with it. I have never had any failures or reboots.
About the only thing I don't like about it is the 1A max discharge rate. But for the price you cant complain too much. For most flashlight users this would be fine. Another point is the heat sink on the side of the charger is not actually connected to anything. Its for looks. The discharge resistor is connected to the bottom of the case, when I say connected its actually only pressed against the metal with some thermal compound.
I ended up gluing a computer fan to the bottom of mine and wiring it into the input side of the charger. So when its plugged in the fan turns on.
I have opened mine.
The only part which connects the power transistors and those big resistor is the bottom part. Then the bottom part "connects" termally with the sides and the top, but the contact is not the best possible.
I agree with you
Thanks for the review Fran! Frontpage'd and sticky'd.
One reboot - but possibly my fault , moving the charger and battery - so may have interrupted the contact ...
Yes = This is a cheap charger - The cheapest one ?
But if you dont get a faulty one [ always possible no matter how much you spend ] , it is very useful ..
DX and many others sell fakes. original is at hobbyking.com and at tomtop also.
original is in other box, buttons are lower in height, sounds are in other tone, and many other differences.
Can Anyone confirm this?

BTW: I did not know this can do discharge for alkalines also.
Testing now a D-cell for capacity.
keep an eye on the temps of the nimh,s when charging 
Yes, or put the temp sensor and "temperature cutoff" to 45ºC
the delta peak some times does not work and can cook the batteries
I have noticed also, when charging "C"-cell NiMh´s, that they tend to get pretty hot...
I have pulled them early and still they reach some 1,48V or so. Can´t see why it is cooking them so long, topping up the last mah´s?
When I use the imax for charging NiMh, I use the "capacity cutoff" and "timer cutoff". In that way, no problems at all
they should get warm but not hot, if the delta peak is not senseing when the battery is full or near full they will get hot as the charger is over charging them, or if your fast charging them cause your in a rush and using high amp rate they might get hot
does not always work
@benckie - "Capacity and timer cuttoff not always work?"
The main way to stop charging NiMh batteries in the Imax is the "delta peak". The delta peak not always work, that´s way it offers 3 more "security features" to prevent overchanging in case the delta peak doesnt work:
1- Capacity cutoff
2- Timer cutoff
3- Temperature cutoff
And all of the 3 works. Is the only way I stop charging NiMh batteries with the Imax, because the delta peak has never worked...
well
1- Capacity cutoff
say if you buy some cheap cells like 10 000 mAh D cell,s but in real life they only take 4500 mAh and the second one takes 5200 mAh and the third one takes 4700 mAh and the fourth takes 5300 mAh so you have to set the capacity cutoff to the lowest mAh rating so the other 3 batteries dont get to take there full capacity.
or worse the guy who is new to hobby chargers sets the capacity cut off to 10 000 mAh and there for over charges the batteries, or he buy,s some cheap 2400 mAh 18650,s that only take 900 mAh not as much of a big deal with li-xx as its about voltage not peak, but there still is the potential of over charging.
to truly set the Capacity cutoff for nimh you have to cycle each battery a good few times till the battery has leveled out and set it to the lowest of all batteries you have or record the time and mAh of every battery you have and mark them and change it to suit each battery, but to do this you have to cycle the batteries and if the delta peak does not work well its to late then realy isnt it as the batteries could already be cooked by some one who does not under stand.
2- Timer cutoff
we that works much the same way as the capacity cutoff, if will depend how many mAh the battery will take, if the batteries are dead flat, half flat or doing a quick top up, or you have to fully discharge them to the minium voltage and full charge each battery and with the maxium discharge of 1 amp that the imax b6 has that can take all day with big cells.
to truly set the Timer cutoff for nimh you have to cycle each battery a good few times till the battery has leveled out and set it to the lowest of all batteries you have or record the time and mAh of every battery you have and mark them and change it to suit each battery, but to do this you have to cycle the batteries and if the delta peak does not work well its to late then realy isnt it as the batteries could already be cooked by some one who does not under stand.
this feature is best to make sure you dont forget and leave your charger charging all night
3- Temperature cutoff
is the best one, but it will depend if its a hot day or a cold nite or summer or winter inside side or out side charging as for me there can be upto 20 degrees diffrence but it has to be the best out of the 3 saftey features, realy you need a good charger with delta peak or where you can adjust the sensitivity so you dont damage you nimh.
its all trial and error with out a good working charger and people new to the hobby chargers can get it wrong easily i have owned a couple of imax b6,s and a imax b6 ac and my old man still runs his imax b6 it pays to check with a DDM and set all cut offs on the safer side (low).
there is alot of factors, users, batteries and conditions its hard to say one settings suits all.
I totally agree with you benckie. I missed the fact that we dont know the real capacity of some batteries unless you first tested them..
However, in the case of Imax, when chargin Li-ion it stops perfectly 4,20 volts. And when charging li-ion, you dont need "capacity cutoff" neither "timer cutoff". You only need "temperature cutoff"
The problem appears only with NiMh. If delta peak doesnt work, you need to "guess" the capacity. But thanks to god, I only use good known batteries...
for that reason i would only suggest the imax b6 geniune and clones for li-po and li-on charging as its about voltage not peak and it should under 50 mv out per cell give or take. with the imax b6,s ive had one was okish and one was an under charger and my old mans is an over charger.
So according the pics, this is fake/clone Imax charger. Right?
