I have these. They are in series, but I easily modified the holder to be parallel. I soldered the red and black wires together, and soldered a new wire to the other end. Perfect.</p>

Another clue is the orientation of the left and right battery. The positive and negative ends are aligned with each other. Had they been in parallel the positive end of one would have been aligned with the positive end of the other battery. Not to say there couldn't be some crazy wiring to contradict what I'm describing, but that would add unnecessary expense to the part.</p></p>

I'm not sure of the exact gauge, but the safe current limit is certainly no more than 2A. Many 18650 are intended for bright led flashlights and have current limiting at 2-2.5 A. I use these holders on small robots which draw < 2A.<p>If you need higher current, I recommend Li batteries designed for RC hobbies. These will yield much higher current and have suitable connectors. Be aware that RC cells usually have NO internal protection.</p></p>

Typical battery holders like this have pretty tiny leads; I hope these are at least a little bit beefier.<p>I'm going to order a few of these. If it hasn't been posted by then, I'll post what gauge the leads are.</p></p>

I have some 18650s with 10C discharge capability, are these holders sufficient? I've had 18650 holders melt from the current before, and am looking for holders that can take the current.</p>
