Hello,

I would like to go with Lipo setup now. And here is my setup:

1- MRC Super Brain 989 8-Cell Lithium Polymer Charger
2- Great Planes Series Deans U 2 to 1 Adapter
3- Astro Flight Blinky LiPo Battery Balancer (2)
4- NeuEnergy 3s 25c Car Lipo pack (2)

Now I need info about my setup If I may ask :)

1- Can I charge 2 3s in Series with Series Deans U 2 to 1 Adapter and SB 989?
2- Can I use 2 of this balancer while charging them in Series? and here is the example in youtube to how you use this balancer
3- What the time I need to full charge them?
4- What amp I have to set to charge this 2 3s in Series?

Thanks
