Yes, you only need the positive and negative wire on the balance plug for the fan to work

It can be if you apply too much heat to the battery. Be careful.
If it isn't broke, fix it anyways!
And don't make a short circuit with your solder iron.

Ah, yes....voice of experience?  (I did that once - scared the crap out of me!) Big Grin
No lucky not, but I was still a bit nervous when I have to solder 3 pieces of 3S 5000 mAh batteries. I saw the movies what could happend so extra careful.

@christopher, heating up any battery is not smart, putting soldering iron there not safe, yet if you apply flux and do the soldering quickly you are good to go, i've salvaged few cells from dead batteries( good practice) and turned dead 4s to 3s and dead 3s to 2s only watchout for shorts "bzzzzzzz"
All the best

Don't buy the batteries in the video. They are cheap Chinese JUNK! Buy either Samsung 25r, LG he4/he2 or Sony VTC4/VTC5. I am using the LG HE4 with my base station and they will run for over a hour of run time.
