Although the battery in the Proto X is not designed to be swapped out after every flight like many small quadcopters, with care, it *can* indeed be easily replaced when necessary. (no soldering required)

Carefully pry the fragile tabs on the bottom of the Proto body and remove. You will find that the battery is stuck to the circuit board with double sticky tape. Carefully pry the battery from the board (use slow steady force to avoid breaking the board). Unplug the battery. The double sticky can be removed from the old battery for re-use, if necessary. Pre-bend the battery wire to match the old shape. Plug in the new battery and stick it to the board. Replace body and check the "trim" of the quadcopter. The battery *might* need to be re-positioned if the trim is way off, but in most cases, it is unlikely to need adjustment.

I bought these for my 2 Proto X. They were easy to install, but the wires were a little stiff and thicker than the original wires. It took a little time to loosen them up so the battery would not pull away from the board. that is why 4 starts and not 5. There is mounting tape right on the batteries, which I liked. If you have a Proto X, these are a great replacement and worth buying.

I'm only getting about 1.5 minutes of flight time before the lights on the Proto X start blinking compared to 3.5 to 4 minutes with the original battery. Not sure what is up, but they show a full charge and look fine otherwise. I'm using a HiTek X1 and charging them in parallel.

They work in my quadcopter but the run time I get out of these is not quite as good as the stock ones. Easy to install and they do work.

Product came just as described and brought a fresh life to my Estes Control Syncro. I can again fly around the office for about 5 minutes instead of the ~1 minute the old battery had been reduced to. Swapping out the battery was an easy process so it was really a plug and play solution.

I would not recommend If your using these for the Proto-X Slt. The negative wire placement is not ideal. All four batteries that I purchased had the neg/black wire came loose after only a couple of flights. Run times were fine, wire quality and placement are lacking.

I bought it to extend flight times for Inum foam plane. The first battery worked great - long flight times. Second battery the negative lead brok off from battery before first flight. The wires from the battery to the plug are VERY stiff for this size battery .

haven't had to use them yet I was thanking I would just replace each time they would run down but that's kind of hard when the charger plugs into Quad. I guess you could charge them all one at a time and do it that way if you wanted to.
