- I have been using the new charger for about 3 weeks now and have charged and discharge 6s and 3s packs. It is truly two chargers in one and the color read outs are great. Not to bad on the learning curve and you can pick it up fairly quickly. Progressive will help you answer questions if you have any. Can charge two 3400mah 6s packs from storage @ 1.5c in 20 minutes. I now always leave my packs at storage after done flying unless I know I will use them the next day. But 20 minutes too get flying is not bad for me. Good value nice machine.
Holy sh!t this is overkill for my needs but its less of an overkill than its big brother the 4010 which meant I saved a good chunk of money.
Love the interface and swivel color screen which put this a cut above the other chargers just based on user friendly factor, yet at the same time overloading you with all the data whether you use it or not.
Alas, It still resembles your Super nintendo of bygone years, albeit a less retro version(looking at u 4010) with a more appealing color scheme.
Con: I wish the balance board were smaller, matter of fact I will make my own hybrid 2s balance connector that plugs directly into the balance port
Just bought the 308 Duo on a whim and am really happy with it. I thimk I'm going to sell my other brand 720 Duo which has been a great charger but I like this one so much more. Maybe I'll keep both for charging many pack but this one is my favortie.
The one complaint I have is the balance port boards that came with it only go to 6S not sure how I can charge 7S. 8S can go directly into the charger balance port. I dont have 7S packs so it doesn't limit me just not sure why the balance boards don't support the 7&8 S packs.
This unit is physically smaller than the 4010 which is nice.
Packing the same feature set as it's big brother the 4010 in a much smaller package + USB charger - good for charging the GoPro in my camera ship.
Even smaller than I expected - awesome!
