The RELiON 12V 300Ah deep-cycle lithium battery is the perfect replacement for a group 8D sized battery. Weighing in at only 83 lbs it’s a relatively lightweight alternative to lead-acid and one of the most popular lithium batteries.
The RB300 surpasses expectation by being versatile, compact and more powerful than its lead-acid counterparts. It’s the perfect combination of size and capacity to fit many applications including, RV, marine, solar energy systems and more.
RELiON lithium iron phosphate (LiFePO4) batteries provide more energy for high consumption than traditional lead-acid batteries. They also offer fast charging and discharging, high efficiency and a longer cycle life – plus no maintenance!
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.
Wee Expert Tip - Use a Victron SmartShunt battery monitor to conveniently read out battery parameters, like state of charge, time to go, historical information and much more via a Bluetooth connection to the VictronConnect App on your phone (or tablet).
