RELiON RB52-LT Lifepo4 Lithium Ion Battery (12V / 52Ah / Low Temp 4SC)

RELiON RB52-LT: Cold Weather Lithium Battery 12V 52Ah Deep CycleRELiON RB52-LT is a 12V 52Ah lithium battery and is part of Low-Temperature Series. This compact and powerful lithium iron phosphate battery is specially designed for cold weather performance. The LT Series batteries can safely charge at temperatures down to -20¡C (-4¡F) using a standard charger. The system features proprietary technology which draws power from the charger itself, uniformly heating the cells within the battery to 41¡F (5¡C), so that it can be charged at its full recommended current. LT batteries require no additional components such as heating blankets.The entire process of heating and charging with the LT Series is completely seamless. Simply plug the battery into the regular lithium charger and the internal heating and monitoring system takes care of the rest. Because it takes time to heat the cells, the charging process in below-freezing temperatures could take a little longer.The Low-Temperature Series battery has the same size and performance as other RELiON batteries but can safely charge when temperatures drop as low as -20¡C using a standard charger. The RB52-LT is a perfect choice for use in off-grid solar, remote monitoring, and in any application where charging in colder temperatures is necessary.Applications: Recreational Vehicles, Marine, Solar, Camping & Backup PowerElectrical SpecificationsCapacity @ 25A: 120 minResistance: ²50 m½ @ 50% SOCEfficiency: 99%Self Discharge: <3% per MonthMaximum Modules in Series: 1 (Single-use)Mechanical SpecificationsCell Type: CylindricalChemistry: LiFePO4Discharge SpecificationsMaximum Continuous Discharge Current: 50 APeak Discharge Current: 100 A (7.5 s ±2.5 s)BMS Discharge Current Cut-Off: 150 A ±20 A (10 ±5 ms)Recommended Low Voltage Disconnect: 11 VBMS Discharge Voltage Cut-Off: 9.2 V (2.3 ±0.1 vpc) (140 ±60 ms)Reconnect Voltage: 10 V (2.5 ±0.1 vpc)Short Circuit Protection: 200-600 _sCharge SpecificationsRecommended Charge Current: 2.5 A - 25 AMaximum Charge Current: 50 ACharge Current 14 to 32 ¡F (-10 to 0 ¡C): ²0.1 CCharge Current -4 to 14 ¡F (-20 to -10 ¡C): ²0.05 CRecommended Charge Voltage: 14.2 V - 14.6 VBMS Charge Voltage Cut-Off: 15.4 V (3.85 ±0.025 vpc) (1.1 ±0.4 s)Reconnect Voltage: 14.6V (3.65 ±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)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)Heating Element SpecificationsHeating Temperature Range: -4 to 41 ¡F (-20 to 10 ¡C)Heating Time: 1 hr @ 4 A
