Best-in-Class Lithium-ion Battery Protection
Early warning of lithium-ion battery failures and prevention of thermal runaway
Compatible with all lithium-ion battery form factors and chemistries
Li-ion Tamer GEN3 is a plug-and-play rack system that improves safety by sensing the off-gassing that precedes thermal runaway battery failures much earlier than smoke or traditional LFL gas detection would.
Product categories
Sensors detect lithium-ion battery electrolyte solvent vapours (off-gas detection), provide temperature and humidity monitoring of the space. Sensors transmit off-gas, temperature, and humidity readings via CANbus to the Hub.
Assembly comprises Li-ion Tamer G2+ sensor and Interface Module. Provides relays, Modbus 485 and CANbus outputs

Technology Integration
Li-ion Tamer® is designed to provide enhanced safety for your battery systems and can be installed at a wide range of integration points throughout your design. Off-gas begins as gases that are generated inside individual cells due to exothermic reactions which begin to occur as a result of internal problems in the battery or external abuses. The release of these gases is the first stage of a battery failure which can self-propagate until the battery begins to smoke and go into fully developed thermal runaway. The ability to detect the gases provides a signal capable is providing early warning of the eventual cell failure and can enable actions which can help mitigate the effects of the battery failure. Li-ion Tamer® products are designed to detect and protect from individual modules, to EV batteries, to room level integrated solutions.
frequently asked questions
- Li-ion Tamer is designed to respond to volatile organic compounds (VOCs) which are emitted during a lithium-ion battery off-gas event that occurs prior to thermal runaway. The initial off-gas event consists of primarily battery electrolyte solvent vapours.
- The off-gas event may also be referred to as the initial cell venting and is defined as the event in which the cell case vents due to a rise in the internal pressure of the cell.
- Li-ion Tamer will also detect the composition of gases (CO, H2 , hydrocarbons, etc.), released at thermal runaway.
- Lithium-ion battery chemistry refers to anode and cathode chemistry, such as LFP (Lithium Ferro-Phosphate or lithium iron phosphate) or NMC (Nickel Manganese Cobalt).
- Yes, Li-ion Tamer can detect the initial cell venting (off-gassing) of different lithium-ion battery chemistries. It does this by detecting the presence of battery electrolyte solvent vapours which are common to all battery chemistries. It is agnostic towards the types of anode and cathode chemistries used.
- Li-ion Tamer can detect off-gassing of different lithium-ion battery chemistries; it does this by detecting the presence of battery electrolyte solvent vapours which are common to all batteries.
- The off-gas event, or cell venting, is a distinct stage in the stages of a battery failure which occurs prior to the onset of thermal runaway for most forms of battery abuse.
- Off-gas events are the earliest indicator of thermal runaway and once detected provides sufficient time to initiate containment measures, such as automatically isolating the components of the ESS or otherwise placing it in a safe condition. This action provides a barrier to the onset of thermal runaway.
- Other mitigating actions can be explored based on system constraints, including increased cooling, local alarms, remote alarms and ventilation activation to remove flammable gas accumulation.
- The Li-ion Tamer product typically provides between 2 and 30 minutes warning of a thermal runaway event. The severity of the abuse factor greatly affects the amount of time between the cell venting and thermal runaway.
- When using the UL 9540A recommended failure method (overheating), Li-ion Tamer consistently delivers early warning with many different types of cell manufacturers, chemistries, and form factors.
Markets We Serve and Beyond
Lithium ion batteries provide power and energy densities demanded by many of today’s energy storage needs. For this reason, lithium ion batteries are being utilized in battery systems across a wide range of markets. Li-ion Tamer® battery monitoring systems are designed with the flexibility of these markets in mind. The operating principles of the monitoring systems are applicable to all lithium ion battery chemistries, form factors, and battery system layouts; they also operate independent of the operational state of the batteries and can even provide valuable monitoring of batteries during shipping and storage.
