LED Status Codes
The Smart Battery Sense has two LEDs: a Bluetooth status LED (blue) and an
Error LED (red). Here are the different LED status codes
- Blue LED
- Slow blinking : The device is ready to accept a Bluetooth connection.
- Fast blinking : Firmware update mode. Wait for the update to complete before using the device.
- Red LED
- On : Hardware error. The device will not be visible in VictronConnect and will not contribute information to the VE.Smart Network.
- Off : No error.
- Fast blinking : Firmware update in progress.
- Slow blinking : Connected and programming.
Troubleshooting
If you encounter any issues with the Smart Battery Sense, please consult
both the VictronConnect manual and the VE.Smart Network manual for
troubleshooting steps.
FAQ (Frequently Asked Questions)
-
Q: Can I use the Smart Battery Sense without a VE.Direct Bluetooth Smart dongle?
A: Yes, the Smart Battery Sense can be used as a standalone unit without the dongle. However, using it with the dongle provides additional functionality. -
Q: How do I know if the Smart Battery Sense is functioning correctly?
A: The Bluetooth LED should be slow blinking when the device is powered up and ready to accept a connection. If both LEDs remain illuminated or if there is a hardware error, the device may not be functioning correctly. -
Q: Can I update the firmware of the Smart Battery Sense?
A: Yes, firmware updates can be performed by connecting to VictronConnect. When the LEDs are alternating quickly for more than 30 seconds, it indicates that the device is in firmware update mode.
Introduction
Smart Battery Sense is a wireless battery voltage-and-temperature sensor for
Victron MPPT Solar Chargers.
The Solar Charger uses these measurements to optimize its charge parameters.
The connection between Smart Battery Sense and one or more Solar Charger(s) is
wireless: It uses VE.Smart Network – a wireless technology based on Bluetooth
Smart.
Simple to install & configure, Smart Battery Sense comes with an inline fuse
and pre-crimped eyelets. Revealing the self-adhesive tape on the back allows
you to mount it directly on the battery.

When can I use Smart Battery Sense …and when should I avoid using it?
- Check the VE.Smart Networking compatible products list for compatible Solar Chargers.
- Smart Battery Sense is not needed, or allowed, in systems which are already controlled by a Color Control GX or Venus GX, see FAQ Q6 for more info.
- Smart Battery Sense is not needed for installations which already have a BMV-712 (battery monitor) with a temperature sensor accessory.
- For installations using a BMV-702 together with its optional temperature sensor accessory – for wireless connectivity consider adding a VE.Direct Bluetooth Smart dongle instead of a Smart Battery Sense.
Installation
- Connect the two eyelets to your battery terminals and attach the unit directly onto the battery-body using its self-adhesive strip.
- For banks of batteries Smart Battery Sense may be connected to any one of the individual batteries.
- If the bat+ and bat- cables are not long enough they may be extended – only make sure you use the same, or a thicker, gauge of cable.
- For Bluetooth pairing of the Smart Battery Sense with your mobile device and the VictronConnect app , see the VictronConnect manual, chapter Bluetooth Smart – Pairing and connecting , which can be downloaded from the Smart Battery Sense product page.

LED Status codes
- Smart Battery Sense has two LEDs: a Bluetooth status LED (blue), and an Error LED (red).
- On power-up, the Bluetooth LED will be slow-blinking – indicating that the device is ready to accept a Bluetooth connection.
- If both LEDs remain illuminated, something is wrong with the Smart Battery Sense unit (Hardware error).
- When the LEDs are alternating quickly for more than 30 seconds, the Smart Battery Sense is in firmware update mode and will need to complete the update before it can be used. Firmware updates are performed (where necessary) after connecting to VictronConnect.
