This TITAN 280Ah lithium leisure battery combines power and convenience in a compact design, offering a capacity of 3.5kWh.

With high-quality cells and a built-in Battery Management System (BMS), it ensures reliability and efficiency. Bluetooth connectivity adds ease of use, and with TITAN batteries, you can count on top performance and value, along with free support from battery specialists.

Built In Bluetooth

All TITAN Lithium batteries have Bluetooth built-in for live and accurate monitoring. Our app is free of charge, available on both iOS and Android and localised in 10 languages.

When connected, users will be able to monitor the battery in real-time and will see live voltage, current (Amps & Watts), live time calculations - how long till discharged and charged, temperature, Ah capacity, % Capacity (SOC), cell voltages, protection triggers and more.

The TITAN Lithium app is also one of the only BMS apps that can handle multiple connections to multiple batteries in series and or parallel, and will adjust calculations to give accurate monitoring based on your setup.

Heater As Standard

This battery comes installed with an heater mat that surrounds the internal cells, which enables the internals to warm up in freezing conditions. 

Battery warm up time will vary on the type of charger and the temperature, but on average, expect an added 20 minutes to your charge time.

The added heater does not affect performance in any way - the battery can and will be able to discharge in -20°C temperatures.

Dual Active & Passive Balancing

All TITAN Lithium batteries come with an active balance system installed. Active balancing is where the internal cells are automatically balanced with each other to ensure all are working equally when discharged and charged by actively monitoring each cell and directing energy to a cell that is lower in voltage than the others, or pulling from a cell that is higher. This system helps avoid overworking a single cell; potentially leading to an early failure.

Passive balance is when the cells are simply connected to each other without actively allocating energy. This method can allow higher voltage differences between the cells and can put more stress on a single cell.

Communication

All TITAN Lithium batteries have communication (comms) ports built into either the top or side of the battery case. These ports are for users who are connecting single or multiple (parallel) batteries to a compatible data-enabled inverter or device.

Connecting to an inverter allows the parameters and live BMS data to be pushed to the inverter or compatible device for a more efficient setup; it will sync and pre-set alarms, low voltage cutoffs, discharge and charge settings, and if using compatible software, can be monitored remotely e.g. using Victron VRM.

Depending on the brand/data protocol, special cables are required for data communication - all cable types are available from TITAN Lithium.

By default, TITAN BMS is pre-set for use with Victron CANBUS via VE.CAN and BMS.CAN ports. TITAN is compatible with Victron's DVCC mode.

Lifetime Warranty

TITAN's warranty covers all components against premature failures caused by manufacturing faults.

Important to note: like anything in life, the more you use something, the more it wears out - batteries have always been the same, and their capacity will degrade over time. This reduction is normal and to be expected; the harder you use the battery (i.e. you discharge it fully and charge it fully often), the faster its fully charged capacity will decrease. Lithium has an incredible resiliency to capacity reduction though, and we expect a capacity loss of about 5-10% every decade with normal use and charging within specifications e.g. a brand new 150Ah would have a fully charged capacity of 165Ah, a 10 year old 150Ah would have ~150Ah and a 20 year old 150Ah would have ~135Ah when fully charged.

Battery wear or capacity loss are not valid warranty claims. Once a battery reaches a fully charged point and it does not last very long or last as long as you need it to, you will need to replace the unit.
