Thinking about building a bigger system (just thinking right now). Looking for a reasonable battery charger. In another thread, the B6AC was mentioned. Will it charge 6S batteries? Looking at the pictures, it seems I would need to somehow connect the main leads and I'm not sure (since I don't have it in front of me) if I'm seeing that right. Edit: Found the answer to 6s in another advertisement (yes). Still would like to know any feedback. Thanks! In addition, the ROBBE was mentioned. Any others and, if you have one of the above, what is your experience?
