My suggestion:
skyrc mc3000 (Google is your friend) 
Pm sent, Miller is no longer around.
Either get a 4 slot charger or a 8 slot charger.
Make sure you make 2 sets, each sets contains the 4 cells you put in series.
Mark/number them so you cant mix them up.
Charge each set as a set in a 4 slot charger. Or charge both sets if you have a 8 slot charger.
Answering questions, I didn’t get any mail information, nor tracking number. And waiting is actually over 5 months long (Paid second part on early December).
I have mailed Lumintop now, lets see 
Awesome. Thanks!
The Miller is but a memory… do not expect an answer to that PM.
That was a problem with at least one group of Payment PM’s sent out. PM Texas_Ace & he will square you away.

EDIT: Oops… looks like this had already been answered…. my bad.
It’s Fixed! Thanks Texas Ace
@ GHOSTSS……. Yep, I did not read to the end before I answered. :person_facepalming: My bad…….
What happened to The Miller???
Over-discharged, currently refresh cycling.
He is a bit overworked with real life and doesn’t have any time for the forums. Maybe he will return when things slow down for him.
The “best” varies from person to person. Do you need it to be cheap, or really fast, or show lots of charging info? There are many chargers out there that get the job done.
Like thijsco19 said, when you run batteries in series, like the 4 cells in a GT carrier, they need to be a matched set and stay that way. So mark them and only use them as a group. “Matched and married” as we say. Lol
Added a set of 35E 18650s and a small donation to the team under a separate order. Thanks guys!
Hello JasonWW Is there a timetable? When will the third group be shipped ?
Paid on 04 April.
Many thanks to all involved developers and the users, who gave their time to this project.
Are you referencing the Miller? I’m a bit confused by that.
Anyway, I would assume Lumintop will be shipping right away. They have the lights. They just need to sort the orders and box them up.
Anyway, it is about Monday morning over in China so they could be shipping some later today. Texas_Ace will be around in maybe 8 or 10 hours and he might have some hard fact details from Neal or Lumintop.
Did you say April 4th? Do you mean April 18th? Please clarify.
Oh Sorry I meant the 18.04, somehow I have problems with the website,
I can not answer normally only quote works and then I quoted the wrong one.
Ordered the GT and a set of 18650. Thank you very much to make this possible. Can’t wait to get it here.
Hi:
I am trying to pay for the GT, but I do not see any external link or password in the PM I received… have I missed something?
does anyone who has bought only a short battery tube got a tracking number?
