Vanguard batteries are made using the top-quality, standardized cylindrical cell format, INR18650MH1 cells made by LG Chem. The cells are based on NMC (Lithium Nickel Manganese Cobalt Oxide or LiNiMnCoO2) cathode technology that has great overall performance and is our technology of choice for electric powertrains.

Our batteries are remarkably safe thanks to our in-house designed battery management system. The system processes all logic and communication; monitors the voltage and temperature at each cell module assembly, along with the current flowing through the battery; and ensures the battery always stays in safe operation. Our system also recognizes reversed polarity and prevents overcharging, deep discharge, or overheating.

Our batteries are designed for a life of up to 2,000 cycles to 80% initial capacity – with no scheduled maintenance needs. All major components are serviceable and cell module assemblies can be replaced rather than having to change the entire battery. On top of that, our batteries are covered by the Vanguard 8-year limited commercial warranty.

OEMs can easily exchange information with the battery pack using its two CANbus ports. One CANbus uses the J1939 automotive standard, while the other is designed for uncomplicated data transfer with the OEM's current communication network: No reprogramming of that network is required. In addition, the battery modular design and use of standardised cylindrical cell formats (18650 / 21700) allow Vanguard to keep the same battery pack dimensions even if there will be new technology available in the future.

With a discharge temperature range from -20 °C to +60 °C, and a charging temperature range from -10 °C to +50 °C, our batteries are specifically designed for extreme conditions. The batteries provide their full capacity and performance until they reach the battery management system protection levels.
