Walkera QR X350 Battery Monitoring bypass for longer flight time

First of all, thanks to Randall Lee who discovered of doing this modification. This modification is only for QR X350 and not really sure for Walkera QR X350 Pro. I had tried this very easy and safe for the MCB. No added weight and no UBEC to be used. With this modification, your Walkera QR X350 will no longer drop from the sky due to low voltage cut-off!! But purchasing Low Battery Alarm is HIGHLY RECOMMENDED to safe your lipo or you can use a timer. Once the alarm was ON at 3.6V per cell and land your QR X350 as soon as possible to prevent further battery power dropped. Never drained the battery  below 3.3V per cell and you will damage the lipo.

 Low battery alarm or any low battery monitoring device (some with digital display available) is HIGHLY RECOMMENDED.

First remove the plug from the Check Power of the MCB as shown.

Make sure disconnect the power/lipo and cut the white and red wire.

Remove the insulator on both white and red wire then connect together. By doing this, it will bypass the LVC. I recommended to solder the wires for security.

A closer look...

Use shrink tube or insulation tape to prevent any short circuit.

Lastly REMEMBER to plug in back to Check Power port or else the board has no power. Secure the wires with cable ties and put back the cover and props. You are done!!!
