By measuring voltage at the battery bank terminals, errors arising from voltage-loss due to cable resistance are avoided - guaranteeing the correct charge-voltage. For lead batteries, battery temperature data is used to adjust the charge-voltages: cold batteries require an increased charge-voltage, whereas hot batteries require a decreased charge-voltage. For lithium batteries temperature data is used to disable charging when they are too cold: charging lithium batteries near or below freezing causes permanent damage to the cells. No additional wires needed between the two units Very easy to set-up and connect to both the app and the Victron MPPT via their VE.Smart Networking: 1) Start by connecting to the newly installed battery sense in the App (it will automatically suggest to update firmware if required (If you have an active 4G or WiFi on your device). 2) clicking on the cog and the VE.Smart Networking allows you to either create or join an existing network 3) If MPPT is not already on a network, you then just go back into the MPPT controller, to the cog icon then to VE Smart Network and then join this product to the network. Hey presto! all done! No issues with the Bluetooth range and you are left with a tidy setup Review: Great - Works great stops the lithium batteries charging below 5 degrees. ## Features - Use the MK3-USB to connect the products to a computer for configuration and firmware updates - Suitable for the following products:Multi, MultiGrid, MultiPlus, MultiPlus-II, Quattro, Inverter/Charger settings in ECOmulti, EasySolar, EasyPlus, and Inverters with a VE.Bus communication port ## Technical Specifications | Specification | Value | |---------------|-------| | Display type | LED | | Manufacturer | Victron Energy | | Part number | ASS030140000 | | Item Weight | 5.66 g | | Product Dimensions | 10 x 3 x 20 cm; 5.67 g | | Item model number | ENG-VT-00033 | | Size | VE.Bus zu USB | | Style | VE.Bus to USB | | Power source type | Solar powered | | Item Package Quantity | 1 | | Included components | Components included in the description | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Colour:** black - **Brand:** Victron Energy - **Product dimensions:** 12.7L x 5.1W x 12.7H centimetres - **Material:** Plastic - **Item weight:** 0.2 Ounces ## Images ![Interface MK3-USB (VE.Bus to USB) - Image 1](https://m.media-amazon.com/images/I/61uVPYmSW8L.jpg) ## Questions & Answers **Q: Is this the usb equivalent to the blue tooth smart dongle? or does it have additional features the bluetooth smart dongle doesnt have?** A: This will do much more than the bluetooth attachment. This will let you modify settings such as custom charge profiles, adjust power assist on comparable units, enable soft surge buffer and many other settings, along with doing everything the Bluetooth can do. The bluetooth is for monitoring and selecting max Amps connection for power assist, you can not change settings. In using the MK3-USB with a double din android stereo as a all in one multimedia/ info center and controller for my mulitplus-ii 2x120 the newest of the victron units so ignore the recommendation thats its for the "older" gear only **Q: Does it work on a MacBook Air?** A: Yes, as of late 2020 this will connect to an Apple product and operate via the Victron Connect App. You no longer need Windows for this to work, however there are still a very few settings that cannot be changed within Victron Connect. Most folks will not need to adjust these settings though. **Q: Is this best to use Mac or windows based tablet with this, I haven't purchased tablet yet. Iam more comfortable with windows.** A: Both MAC and Windows work with this device. Windows has more functionality because some of the Victron programs don't run on Mac. **Q: Does this product come with a ve.direct 4-pin cable with which to connect to the target device? the photos shows a usb cable that goes to the computer** A: This is a VE.Bus adapter, for connecting to a Multiplus or Quattro inverter/charger. Those devices do not have VE.Direct connections. If you have a VE.Direct device, like a solar controller or battery monitor, you can use a VE.Direct to USB adapter. ## Customer Reviews ### ⭐⭐⭐⭐⭐ East to fit and setup *by K***H on 25 May 2021* Useful addition for the Victron MPPT controller to enable efficient battery charging based on voltage and temperature.

The Sensor was simple to install as the eyelets bolt directly to the battery terminals. Once I connected the Victron Connect app on my phone to the Sensor, the app immediately downloaded new firmware for the Sensor. It rebooted and connected to my phone app at once, displaying the voltage and temperature of the battery (or pair of batteries in my case). I've included a screenshot showing the background voltage of my batteries (12.7v ie 100% charge), the voltage dip as the starter motor turned the engine over, and then the initial charge voltage when the engine started, a perfect 14.2v from the new alternator. Exactly what I needed to know, everything is working perfectly in the LC. The story doesn't end there. I also have an old campervan and I'd like the same confidence in its charging system and starter battery, the battery being at least 6 years old. My solution was to buy some industrial velcro on Amazon and put the bluetooth sensor in a tight pouch of female velcro. With a strip of male velcro stuck to the top of the battery, the sensor can be moved from vehicle to vehicle as required, once unbolted of course. ## Frequently Bought Together - Victron Energy Interface MK3-USB (VE.Bus to USB) - Victron Energy RJ45 UTP Cable, 2.95 Feet (0.9 Meters) - Victron Energy VE.Bus Smart Dongle (Bluetooth) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/53733235-interface-mk3-usb-ve-bus-to-usb](https://www.desertcart.kr/products/53733235-interface-mk3-usb-ve-bus-to-usb) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-25*
