LiFePO4 Battery 135Ah 12V, under-seat size, self-heating with bluetooth-comunication - RENOGY PRO

Renogy Pro Series 12.8V 135Ah Smart LiFePO₄ Battery

The Renogy Pro Series 12.8V 135Ah Smart LiFePO₄ Battery is a compact, high-performance energy storage solution for demanding mobile power systems in camper vans, motorhomes, boats, or off-grid applications. Thanks to its compact form factor, it is particularly well suited for under-seat installation in vehicles such as those based on the FIAT Ducato.

The battery is based on high-quality LiFePO₄ cell chemistry and offers a high energy density combined with a long service life of over 4,000 cycles (80% DoD). This makes it ideal for systems with a consistently high energy demand.

An advanced Battery Management System (BMS) with more than 60 protective functions ensures safety and longevity through overvoltage and undervoltage protection, short-circuit protection, temperature monitoring, and active cell balancing. Via integrated Bluetooth, status information and system data can be conveniently monitored in real time using the Renogy App (DC Home).

The integrated self-heating function enables reliable charging even at very low temperatures and ensures operational readiness in cold climates. It activates automatically when temperatures drop.

Thanks to its robust IP65 protection rating, compact dimensions, and specially designed housing, the battery can be flexibly integrated into professionally engineered energy systems, even under seats or in confined installation spaces.
