Advanced IP67 rated 12V 100Ah Lithium Iron Phosphate battery with On/Off button, advanced communications protocols and easy scalability.

The Pylontech RT12100G31 battery has been developed to provide adaptability and scalability to applications from Marine, RV/Caravan, 4×4 and other solar storage systems.

The Intelligent BMS provides the ultimate in safety with temperature protection, over-voltage, over-current and short circuit protection to ensure safe operation, high reliability & zero maintenance to extend service life.

However, it’s the advanced communication protocols built in that is the biggest advantage! Incorporating the RT12100G31 into your power system is also simple when combined with a Victron Energy GX device , allowing monitoring & control from existing battery system monitors or marine glass bridges.

Being an “array aware” or managed battery, The RT12100G31 allows for expansion by allowing the BMS to communicate with each other in a master/slave format. This allows for the battery system to increase maximum continuous discharge @ 1.0C up to 8 batteries (e.g 1S4P will provide a Max. cont. discharge of 400A, with an 800A pulse discharge for 30 seconds.


  • A 12V System (1S) can be scaled up to 16 in parallel
  • A 24V system (2S) up to 8 in parallel
  • A 48V system (4S) up to 4 in parallel

*For systems of 1-8 batteries, the maximum continuous discharge is 1.0C, for system of 9 batteries or more, the maximum continuous discharge is 0.8C

As Lithium batteries provide clear advantages over traditional lead-acid batteries with longer service life, deeper discharge capability, more usable capacities and much lighter weight, the RT12100G31 is a great solution for many applications.
