Awesome, Yea, I originally only bought the 3S's but I found a black friday deal on a 6S i couldn't pass up.I have the dynamite version. I've only used it to charge 2S and 3S lipo packs. I have an old NiMH/NiCAD charger I use for those and another charger (2x20/2x200W) I use for parallel charging.
The only pack it's going to have issues with is the 6S 5000mah pack as that needs 111W to charge at 1C. It won't be an "issue" really, but you will be charging it a hair under 1C.
I charge 4x5000mah and 4x6200mah 3S packs on mine and set the output to 10A on all 4. It doesn't reach 10A though as it hits the wattage limit, but it still does the job pretty quick.
Back when I used to use 2S packs in my 1/8th and 3S in my 1/10th:
Now I only use 3S packs in everything.
The guy at the store said it should take about 80 minutes to charge the 6S, which sucks, but I'll just have them all charged before going out and recharge the 3S's while the 6S is running in the Kraton.
