I geek this afternoon and think I will take
- Skilhunt M1 http://www.gearbest.com/chargers/pp_293608.html
seems to be more solid, more versatile and more affordable than the xtar mc1 plus
- samsung 30 Q batteries http://www.gearbest.com/batteries/pp_232874.html
they seems to be NCR chemistry so as safe as IMR.
I hope I am not doing an error.
If somebody can confirm that this items are apropriate it will be very nice!
The 30Q’s are great, can’t comment on the charger other than I’m 3 for 3 with Xtar’s chargers and my next will probably be an Xtar too. Very good for the money they are :+1:

This Skilhunt charger look a lot like cheaper liitokala Li-100:
http://www.gearbest.com/chargers/pp_272183.html
It’s a good charger and supports LiFePo4 chemistry (Xtar MC1/MC1 Plus do not).
If you didn’t already, see HKJ reviews:
Test/Review of LiitoKala Lii-100
Test/Review of Charger Xtar MC1
Xtar MC1Plus Review
For ~4USD a piece you can always buy both li-100 and MC1 Plus and have “independent dual slot” charger 
Regarding cells you can not go wrong with 30Qs but take also a look on LG HG2 cells - but beware of fake ones.
Samsung 30Q and LG HG2 comparison 5A
10A comparison
20A comparison
So lower voltage sag over 30Q at any current.
EDIT: well it’s pretty similar at 20A but that current would melt some stuff 
Thank you,
I read this after I buy but have no regrets, the Xtar was a good solution, but I think the Skilhunt is better for me because is all in one, and seems more solid for outdoor carrying. I don’t buy the liitokala because doesn’t know well the mark, but it’s true there are very similar. I will make a review of my kit when I will receive. But one of the item I buy was not in stock, so I think I will receive my order in one month 
If operating and charging batteries outdoors is important, a 5V Folding Solar Panel Charger (too spendy for my needs, but YMMV) would keep you outdoors in style as long as you want — as long as it’s sunny.
If you wanted to DIY a case, this Budget 5W model would still get you almost as many C’s on a sunny day.
Dimbo The Blinky those are not worth the price - especially for just 5W. Better check these:
Blitzwolf 15W solar charger
Blitzwolf 20W solar charger
Price is not the best at the moment (20W was for ~43$ not so long ago, 15W for ~37:money_mouth_face: - if you’re patient it probably will become cheaper or some code will be available.
Thank you for your answers, for know it’s not a need for me.
I choose a solid battery charger because I may be carry it in outdoor, and in France I could find electricity to charge if necessary.
But I keep in mind your solution :+1:
I just post to thank all the members who helped me. And also to gie the link for the presentation of my kit. It might help.
Beginner your are lost? This presentation of my kit might help you.
All the best,
