RELiON RB40 40Ah 12V Lithium Battery

Manufacturer Part#: RB40

This efficient and fast-charging 12V 40Ah lithium battery is powerful yet compact enough to fit in many deep cycle applications. The RB40 is a lithium iron phosphate (LiFePO4) battery with more power, less weight and up to 10x longer life than its lead-acid counterparts. Lithium is the logical choice for applications that will exhaust the batteries or run in extreme weather.

Not all lithium batteries are created equal. All RELiON batteries use the safest and most stable components, including a LiFePO4 cathode and a built-in Battery Management System (BMS). The BMS ensures a long lifetime, safe handling – and high-accuracy State of Charge (SOC) calculations.

What makes this battery different

  • RELiON lithium batteries provide more energy for high consumption than traditional lead-acid batteries.
  • They also offer ultra-fast charging and discharging, high efficiency and a longer cycle life – plus no maintenance!

Where you can use this battery

  • Fishing electronics, robotics, solar lighting, remote power, outdoor adventures, and other deep cycle applications.
