Test/Review of Charger Skilhunt M4D

It has sand color, kinda cool when the other only got black and white.
Thanks again for your review HKJ

This looks pretty good, displays information on all slots at the same time and does 4x1A charging. The price is a bit eeeeh though. I’m receiving a Liitokala Lii-400 in the mail tomorrow that looks like a very similar, if not identical to this and I’m wondering whether that will perform similarly (I’ll have to hook-up my UT71D on it).

Speaking of which, what software do you use to make the graphs? They look beautiful and it seems perfect for such usage (electronics etc).

Use the code on my website to get a better price.

JFreeChart controlled from my software.

Does it have any temp sensors?
The box does mention over-heat protection.

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 .
