This compact, smart device, designed by Telwin specialists, changes the rules of energy management in your vehicles, machines and fleet.
With Bluetooth technology and the intuitive BATTERY MANAGER mobile app, TELWIN BATTERY LINK 2.0 lets you monitor the key parameters of up to 10 batteries at the same time, directly from your smartphone or tablet. Imagine knowing the state of charge, the voltage and the expected service life of each battery without needing physical access to it. That is not only convenient but above all saves real time and money, eliminating the risk of a failure at the least expected moment.
BATTERY LINK 2.0 is your personal energy guardian, constantly watching over the heart of the power system. The device records a data history, which allows trend analysis and early detection of potential problems. Smart notifications inform you of critical changes so that you can act in advance. Whether you manage a vehicle fleet, service customers' machines or simply want to be sure that your camper, boat or classic car is always ready for the road, TELWIN BATTERY LINK 2.0 is an investment that pays for itself quickly, giving you peace of mind and optimum performance.
Advanced Capabilities of TELWIN BATTERY LINK 2.0
Smart Management of Fleets and Multiple Vehicles with the Telwin Cloud
TELWIN BATTERY LINK 2.0 combined with the BATTERY MANAGER app transforms the way energy is managed across several vehicles or machines. The app can monitor up to 10 BATTERY LINK 2.0 devices at the same time, which makes it an ideal solution for owners of small and medium-sized fleets and workshops, as well as for enthusiasts with several seasonal vehicles (motorcycles, boats, campers).
Each monitored device can be given its own name (for example "CAT excavator", "Mercedes Sprinter", "Motor yacht"), which keeps things clear and makes identification easy. A key function is data synchronisation with the Telwin cloud. This means that the history of each battery's condition is stored securely and can be accessed from any device with the BATTERY MANAGER app installed after logging in to your account. This is invaluable for analysing long-term battery condition, planning inspections and diagnosing problems.
Failure Prevention and Real Savings: No More Surprises.
A sudden flat battery is not just frustrating; it often means measurable financial losses, downtime, delays, roadside assistance costs or even damage to the battery itself through deep discharge. TELWIN BATTERY LINK 2.0 is your proactive early warning system. By continuously monitoring the voltage and state of charge (SoC), the device can flag problems as they develop.
The BATTERY MANAGER app sends alerts to your smartphone when battery parameters fall below a safe level or show worrying trends. This lets you take preventive action, such as recharging the battery, checking the alternator or scheduling a replacement, before a failure happens. For companies this means minimising unplanned downtime and the costs that come with it; for private users, the confidence that the vehicle will always be ready for the road and that the battery will last longer.
Universal and Extremely Easy to Use with Any Battery
Telwin engineers made sure that BATTERY LINK 2.0 is as universal and user-friendly as possible. It is compatible with the vast majority of 12V and 24V battery types on the market: from classic lead-acid (WET, MF, PbCa) and technically advanced GEL, AGM and EFB batteries to modern lithium (Li) batteries. This means that a single device can handle practically any vehicle, machine or backup power system.
Installation is very simple and requires no special tools or knowledge. Just connect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal of the battery. The compact dimensions allow mounting even in tight spaces. The BATTERY MANAGER app guides you step by step through pairing and setup, and its intuitive interface makes reading data and managing settings very easy and convenient.

Key Features and Benefits
- Smart Remote Monitoring via the BATTERY MANAGER App: The device communicates wirelessly (Bluetooth Low Energy) with your smartphone or tablet and sends data to the dedicated app. This lets you check the voltage, state of charge (SoC) and other key indicators of several batteries at once, without opening the bonnet or reaching into awkward places. For a professional this means time saved on diagnostics, proactive energy management across the fleet and immediate detection of problems before they lead to costly downtime.
- Broad Compatibility with 12V and 24V Batteries: TELWIN BATTERY LINK 2.0 supports many battery types, including conventional lead-acid (WET), gel (GEL), AGM, MF, PbCa, EFB and modern lithium (Li) batteries with a voltage of 12V or 24V. This versatility makes it an ideal tool for workshops servicing different vehicles and machines, and for users with a mixed machine fleet. It ensures that one device covers most monitoring needs.
- Multiple Battery Management and Data History: The BATTERY MANAGER app lets you pair and monitor up to 10 BATTERY LINK 2.0 devices. Each device can be given its own name for easy identification. In addition, the system records historical data on battery parameters, which lets you analyse battery condition over time, predict service life and spot unusual behaviour. It is a powerful tool for optimising battery maintenance and replacement.
- Real-Time Notification and Alert System: You do not have to keep checking the app: via the BATTERY MANAGER app, BATTERY LINK 2.0 sends a notification to your smartphone when it detects a potential problem, for example a critically low state of charge or a voltage that is too high or too low. This lets you react immediately and prevent full discharge of the battery, damage or problems starting the vehicle or machine.
- Simple Installation and Intuitive Operation: Fitting BATTERY LINK 2.0 is very easy: just connect the red clamp to the positive terminal and the black one to the negative terminal of the battery. The device is compact and needs no special tools. The BATTERY MANAGER app was designed to be easy to use, with a clear interface and quick access to all functions, even for less technically minded users.
- High Resistance and Durability (IP65): The housing of the device meets the IP65 rating, which means complete protection against dust ingress and resistance to water jets from any direction. As a result, BATTERY LINK 2.0 can be used safely in tough workshop conditions, in off-road vehicles, agricultural machines and on boats, providing reliable operation for a long time.
Applications
- Car workshops and service centres: for quick diagnostics of customers' batteries and for monitoring vehicles left for longer periods.
- Vehicle fleets: for transport, courier and construction companies managing batteries in vans, trucks and work machines, minimising the risk of downtime.
- Owners of campers, caravans and boats: for monitoring leisure and starter batteries while parked and on the move, for comfort and energy independence.
