I would like to charger two Lipo 12.6v 3s batteries at the same time off one charger. Can any of you suggest a brand of charger to look at for this?
I have been looking at the Air Thunder 902 charger which is rated at 9 amps. Is anyone familar with this one or could you suggest something else.
Thanks for your help.

I would recomend using the tp1010 it is a great charger and you can wire batteries in serries and charge two at a time with it. I also charge at 2c with it at times.

I would be very careful to charge two batteries in series. There will be voltage difference in group of cells between two batteries. And, the cells can be damaged as one group of cells can be overcharge. Worst if charge at 2C!

Unless you use balancer but I found out it took a long time to balance all the cells for two batteries in series. Faster to charge them individually in this case. I have tried that before.

Now, I use Polycharger 4 to charge all my batteries the same time. However, it is not the best charger and I use four blinky balancer that cost money. I use this charger for quick charge in the field. I will use TP1010 and charge one battery at a time while at home.
