Since you got your answer I still like to add that if you need fast charges you need to buy a double channel V-Lock battery charger, and don't use RED's, if speed is not an issue buy RED's charger with confidence.
As far as RED's Batteries "Bricks" I can say that having been using them for years and having had dozen of them at work, I only had one single problem with one charger, and one single problem with two batteries,
one was fixed and working solid, while one unfortunately failed again and she is a goner.
So RED Chargers and RED Bricks, 3 years of use, all conditions, only those that travel as much as I do, know what it means to any Battery, to go form Freezing cold to boiling hot, both Dry and humid,
indoor and outdoor, Dozens of batteries and Chargers, ONE ISSUE, ONE TIME, that is pretty good adds, I would say.
So counting the thousands of them sold, the ones that had issues, are a super low percentage, it goes back to the same issue with iPhones, when you say that 100k
of them were sent back, you say WOW they are bad,then when you see how many Millions of them were sold, the percentage is very very low ,of unhappy costumers... Just saying... ;)
However for traveling, if you need many Bricks, need to consider restrictions, and better consider other brands that make 100's and 90's as RED's are 140's.
