Our RB48V100 is a 48V 100ah lithium deep cycle battery. This lithium iron phosphate (LiFePO4) battery is ready to replace your lead-acid battery bank in your solar energy system or electric vehicle. It’s powerful, rugged, and has an extremely long cycle life. The 48V100 battery can store more energy and charge faster than lead-acid battery alternatives.

48V100 in Renewable Energy Applications
If you’re looking for energy storage for your residential solar system for grid-tie or off-grid, this 48V lithium battery is a great option. Deep cycle batteries are a key component in off-grid solar electric systems, and for grid-tie or emergency backup power systems with or without solar. For renewable energy systems, the 48V100 battery is compatible with Outback, Schneider Electric, Magnum, Morningstar and many other leading brands of inverters and solar charge controllers.

48V100 in EV Applications
At half the weight and 2-3 times the energy of traditional lead-acid batteries, RELiON lithium batteries provide more hours of driving for your EV application. Your EV will maintain a constant level of power, morning, noon and night (and the next day, as well). Explore further afield, play another round, or power through yet another shift with no worries.

All RELiON Batteries use the safest and most stable components. It is equipped with a LINYI Connector terminal type and a built-in battery management system (BMS). The BMS ensures a long lifetime, safe handling – and high-accuracy State of Charge (SOC) calculations.
