RELiON RB300 Lifepo4 Lithium Ion Battery (12V / 300Ah / 4SC)

RELiON RB300 12V 300Ah Lithium Deep Cycle BatteryThis Group 8D lithium iron phosphate (LiFePO4) battery is ready to replace your heavy lead-acid battery bank in your sailboat, RV or solar energy system. It weighs only 82 lbs for a true 300 Amp Hour lithium battery that provides 100% of its rated capacity. The RB300 gives you the flexibility to replace several small, heavier lead-acid batteries in a single high capacity unit.LiFePO4 batteries are lighter, take less space and last longer. While the up-front cost is higher than Gel, AGM or Lead-Acid the overall cost of ownership is lower over time because they require no maintenance and they have up to 10x longer life.The RB300 offers high, reliable performance in any climate or condition for RVs, campers, sailboats and battery-based solar systems.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.Applications: Recreational Vehicles, Solar, Marine & Electric VehiclesElectrical SpecificationsCapacity @ 25A: 720 minResistance: ²30 m½ @ 50% SOCEfficiency: 99%Self Discharge: <3% per MonthMaximum Modules in Series: 6Mechanical SpecificationsCell Type: CylindricalChemistry: LiFePO4Discharge SpecificationsMaximum Continuous Discharge Current: 100 APeak Discharge Current: 200 A (7.5 s ±2.5 s)BMS Discharge Current Cut-Off: 280 A ±50 A (9 ±4 ms)Recommended Low Voltage Disconnect: 11 VBMS Discharge Voltage Cut-Off: 8 V (2.0 ±0.08 vpc) (140 ±60 ms)Reconnect Voltage: 9.2 V (2.3 ±0.1 vpc)Short Circuit Protection: 200-600 µsCharge SpecificationsRecommended Charge Current: 15 A - 50 AMaximum Charge Current: 100 ACharge Current 32¡F to 14¡F (0 to -10 ¡C): ²0.1 CCharge Current -4¡F to 14¡F (-20 to -10 ¡C): ²0.05 CRecommended Charge Voltage: 14.2 V - 14.6 VBMS Charge Voltage Cut-Off: 15.6 V (3.9 ±0.025 vpc) (1.1 ±0.4 s)Reconnect Voltage: 15.2 V (3.8 ±0.05 vpc)Balancing Voltage: 14.4 V (3.6 ±0.025 vpc)Temperature SpecificationsDischarge Temperature: -4 to 140 ¡F (-20 to 60 ¡C)Charge Temperature: -4 to 113 ¡F (-20 to 45 ¡C) *Refer to charge currents below 0¡C (32¡F)Storage Temperature: 23 to 95 ¡F (-5 to 35 ¡C)BMS High Temperature Cut-Off: 176 ¡F (80 ¡C)Reconnect Temperature: 122 ¡F (50 ¡C)
