New version (6.0) NOW 7.0 of the miller ml-102 charger...

Hi friends.

Just spotted this at cpf

Aparently there is anew version of the ml102…

any info of what is new on the new v6 version of this little gem?

EDITED: now version 7.0 probably 2.1A output pending confirmation

It is a shame Miller did not address the spring for protected cells.

Compared to v5, the board is revised with D3 and J5 pads removed, micro-USB instead of mini-USB (some v5 have micro-USB):

Other side appears the same:

where did you found the info and pics???

the one available at fastech is v5 and ships with micro usb…

and it seems it allows to use protected cells…

I bet this one will terminate at 4.0V

v5 I got from FT has mini-USB and doesn’t fit protected cells

if you check ft page they clearly state is shipping v5 with micro usb…

why this one will terminate at 4.0 v???

the V3 terminated at 4.2V, the version 5 at 4.1V so i assume this one will terminate at 4V (personal experience with the V5)

Actually Chloe

You can ADD a USB micro right next to the USB mini port, see that small empty spot to the right of the Mini port (just above the U1 silk screen letters), that is a location for a USB Micro connector (J5) [well that and a diode (D3) to prevent power feedback]

The only problem…that USB micro only has one set of holder feet, which is the primary reason the XTAR MC1 is so fragile, one good tug and it just pulls it right off the PCB…I just LOVE the TP4056 charge controller too, very good chips

The TP4056 is capable of pushing 1A charge, only thing that needs to be changed is the resistor level (R2) right below the USB mini connector, I just wish it had a slider type holder like the XTAR MC1

Pretty cool, everything left of the double white vertical stripe is for “charging” everything to the right of it is for the boost from 4.2V up to 5vdc for output…really neat design

I’ve purchased 3 of the V5’s from FT - 2 terminate at 4.20V, and 1 at 4.14V or so…
Within tolerance I believe.

TP4056 datasheet

FYI, it’s the EXACT same chip for Li Ion that are on these type little charger modules
http://www.fasttech.com/products/1005/10005926/1585501

HKJ did a review on those modules, a 1A due to the thermal control in the chip at 1A it “fluctuates” maybe a little heatsink or something on that chip might help, he said at 500mA charge rate it was very solid

So the review from above is the review for the “charge” pattern on the Miller

Yep! 4.2 - 1.5% = 4.137
Thanks WarHawk!

Yes, this is true, but I actually prefer the mini USB socket for the same reasons you stated.

I’ve just received ML-102 from fasttech…

and it is version 7…

Anyone know what they’ve changed?

Omg! version 7!!

no idea on what is changed. Thanks for the info…

Hope someone will tell us…

Can’t read all the chip markings. Like U1 or U2.

M3tek MT5032A boost converter for the 5v usb output. Datasheet. Claims to be capable of 2.1A. Can’t know without testing tho. The usb output does not have any charger coding resistors populated (but pads are there to add them) so apple devices will likely charge slower just due to that.

2.1amp output… interesting… no official website?

The chip claims to be to be capable of 2.1A. M3tek is a chinese company, really can’t assume 2.1A is the truth.
The chinese tp4056 li-ion charger chip (used in one ML-102 version) claims 1A. In reality its 850mA.

The chip next to MT5032A is ETA6002, on the other side there is 2x 8205A, 1x VGX6, 1xA1SHB.

I’m totally green in this area, so only thing i can do is read the markings :slight_smile:

I will check charging time today with some Panasonics 3400 and 2900 later today.

Battery charge current depends on what its been set to. Claims to do up to 2.5A. Its a switching charger, should be more efficient.

The output could be checked easily with a usb current tester

please keep us informed…

also… where did you bought it? ft keeps saying 5.0
