WL Toy’s v911 is a fun micro RC helicopter. But because of it’s unique battery connection, you are limited to the factory 120mAh LiPo or recently released 130mAh LiPo. Here’s a mod that takes the battery connector part and turn it into a battery tray so that you can use the popular 1s LiPo with the Parkzone/E-Flite ultra micro connectors.
First, use a wire cutter or nail clippers to cut along the yellow line. Use a file to get everything smoothed out. It should look like the piece on the right when you are done.
Use a pair of wire cutters to cut where indicated. It should look like the piece on the right when done.
Then you can slip into the existing battery slot on the v911 skids. You will also need to solder on some ultra micro plugs.
The new adapter fits right in to form a battery tray. Solder on some ultra micro leads.
For those concern with the stock center of gravity. The fit is tight enough that you can position the battery where you like.
Here, you can see the battery position at about the stock location. Personally, I prefer the Solo Pro location. Fully forward, and into the canopy. :)

You can make the battery tray more secure if you glue it to the skid. I have tested and found that ThunderPower 160, Hyperion 160, E-Flite 120 fits perfectly. I can also fit Turnigy 160 battery as well. Though I have had one where it was too thick to fit. The NanoTech 160 are definitely too thick for this mod. I recommend getting a Solo Pro skids if the battery you run are the NanoTech 160.
excellent mod. i’m going to buy bunch of batteries but stock V911’s are bit overpriced. And with this mod you can get multi-battery charging harness for your decent charger too :)
