A few of these are getting used in the USA now. Mine has been in use a couple years. Mostly Chinese menus. It didn’t like a 10,000 amp short circuit so I removed it for repair. Only 2 shorted mosfets. This was a good chance to clean up the wiring to lcd. Trying RJ-45 All 8 wires are used. 4 from the com port 2 for lcd backlight power 2 for switch Not much else to say. Most RJ45 are wired pin to pin. A little solder and shrink tube makes a plug in display. ![MVC-012F](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/1/17a75ca501b0448f76254b5f52a3ddf08f65826b.JPG) ![MVC-011F](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/c/ca832f37cd2a1d533c89a4d882e275d9a187d524.JPG) ![MVC-013F](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/d/d3a1f85366f7e589a9f8708e4e5a45f8c04de520.JPG). ---

To test Bluetooth, need only B- and B+ connected. Red wire, last pin, is B+. Hold button 3 sec to boot. ![HTB1vnLIquuSBuNjSsplq6ze8pXa2](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/e/e44fe8b2d3af948b86a6d856e1b778735bda1138.jpg) ---

Optional LCD display. 4 wires connect color to color from bms to display. Rj-45 makes for neat connection. Use two of the 8 wires for 72v battery power to display. > **[4.7x4.7x3.5" ABS PLASTIC ELECTRONICS PROJECT BOX ENCLOSURE HOBBY CASE SCREW...](https://www.ebay.com/itm/ABS-PLASTIC-ELECTRONICS-PROJECT-BOX-ENCLOSURE-HOBBY-CASE-SCREW-IP65-115x90x55mm-/302211965984?hash=item465d3ca420)** > > Waterproof rate:Ip65.
