RELiON RB100 12V 100Ah Lithium Deep Cycle Battery Longer runtime equals more recreation time with the RB100. This 12V 100Ah deep cycle lithium battery is the perfect replacement from a group 31 AGM, GEL or lead-acid Battery. Weighing only 30 lbs it's a lightweight alternative to lead-acid and one of RELiON's most popular lithium batteries. The RB100 surpasses expectations with its versatility, compact design and increased power than its lead-acid counterparts. It's the perfect combination of size and capacity to fit many applications including, marine, RV, solar energy systems and more. 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 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. Why Choose RELiON Lithium Batteries? - Longer Life: A much longer life span compared to lead-acid batteries – up to 10x longer! - More Hours of Power: A 25-50% high capacity than lead-acid batteries, with full power available throughout discharge. - Low Self-Discharge Rate: Which means a long shelf life, up to a year, between charges. - Highly Efficient: Fast recharge times and a 99% efficient recharge process, which means less wasted electricity. - Lighter Weight: Typically half the weight of lead-acid batteries. - Partial State of Charge Tolerant: If operated in PSOC there is no damage to the battery. This is the leading cause of early failure of lead acid batteries. - Lower Overall Total Cost of Ownership: Changing batteries less often means fewer replacement and labor costs.
