LIONTRON Lithium LiFePO4 LX Smart BMS 12,8V 300Ah RV underseat battery

LIONTRON® LifePO4 300Ah batteries are a complete 12V lead acid battery replacement with all the advantages of lithium iron phosphate with fully integrated BMS and Bluetooth monitoring. It offers significant weight reduction, enormous power reserves and stable tension even under extreme loads.

The battery was specially developed to replace lead-acid batteries “one by one” and to fully meet the high demands placed on storage batteries today.

Thanks to the latest lithium technology, the highest level of safety and a long service life are guaranteed even if the battery is regularly deeply discharged. They allow for an extremely long service life (more than 3000 cycles at 90% DoD) and make LIONTRON® batteries the ideal traction battery. The battery is only suitable for a 12V installation. A parallel connection is possible to increase capacity (serial connection to 24V / 48V is not possible). Bluetooth monitoring Battery status always at a glance With integrated Bluetooth 4.0 monitoring, you always have all important battery data in view on your smartphone or tablet. Among other things, the application displays the following data in real time:

  • Battery State of Charge in % (SoC)
  • Battery voltage
  • Charge / discharge current
  • Remaining capacity
  • Battery temperature
  • Number of charge / discharge cycles
  • Rated / capacity

To connect the battery and a smartphone/tablet, the device must support Bluetooth version 4.0.

The safest lithium technology

The batteries are based on lithium iron phosphate (LiFePO4) technology. This is currently the safest lithium technology. Each battery consists of a high-performance lithium iron phosphate (LiFePo4) accumulator and an integrated battery management system, or BMS for short. This constantly monitors the status of the individual cells and protects them against overloading, overvoltage, and overheating, among other things. The BMS prevents in advance a premature failure of the storage unit due to environmental influences or incorrect use.
