This 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.\r\n\r\nThe 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.\r\n\r\nThe 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. Chilly nights off-the-grid are now easier with the RB300-LT - perfect for RVs, Sprinters, Class A vehicles, Class C vehicles and more!\r\n\r\nApplications: Recreational Vehicles \u0026amp; Backup Power\r\n\r\nElectrical Specifications\r\nCapacity @ 25A: 720 min\r\nResistance: ≤30 mΩ @ 50% SOC\r\nEfficiency: 99%\r\nSelf Discharge: \u0026lt;3% per Month\r\nMaximum Modules in Series: 1 (Single-use)\r\n\r\nMechanical Specifications\r\nCell Type: Cylindrical\r\nChemistry: LiFePO4\r\n\r\nDischarge Specifications\r\nMaximum Continuous Discharge Current: 100 A\r\nPeak Discharge Current: 200 A (7.5 s ±2.5 s)\r\nBMS Discharge Current Cut-Off: 280 A ±50 A (9 ±4 ms)\r\nRecommended Low Voltage Disconnect: 11 V\r\nBMS Discharge Voltage Cut-Off: 8 V (2.0 ±0.08 vpc) (140 ±60 ms)\r\nReconnect Voltage: 9.2 V (2.3 ±0.1 vpc) 8.8V (2.2±0.3V\/cell)\r\nShort Circuit Protection: 200-600 μs\r\n\r\nCharge Specifications\r\nRecommended Charge Current: 15 A - 50 A\r\nMaximum Charge Current: 100 A\r\nCharge Current 14 to 32 °F (-10 to 0 °C): ≤0.1 C\r\nCharge Current -4 to 14 °F (-20 to -10 °C): ≤0.05 C\r\nRecommended Charge Voltage: 14.2 V - 14.6 V\r\nBMS Charge Voltage Cut-Off: 15.6 V (3.9 ±0.05 vpc) (1.0 ±0.5 s)\r\nReconnect Voltage: 15.2 V (3.8 ±0.05 vpc)\r\nBalancing Voltage: 14.4 V (3.6 ±0.025 vpc)\r\n\r\nTemperature Specifications\r\nDischarge Temperature: -4 to 140 °F (-20 to 60 °C)\r\nCharge Temperature: -4 to 113 °F (-20 to 45 °C)\r\nStorage Temperature: 23 to 95 °F (-5 to 35 °C)\r\nBMS High Temperature Cut-Off: 176 °F (80 °C)\r\nReconnect Temperature: 122 °F (50 °C)\r\n\r\nHeating Element Specifications\r\nHeating Temperature Range: -4 to 50 °F (-20 to 5 °C)\r\nHeating Time: 1.5 hr @ 15 A","brand":"RELiON","offers":[{"title":"Default Title","offer_id":51860797554952,"sku":"REL-RB300-LT","price":3112.94,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/5825\/9208\/files\/59f8a896-5ac2-4c3b-87b9-f29b78273fc6.jpg?v=1751320233","url":"https:\/\/mecleisure.co.uk\/products\/relion-128v-300ah-low-temperature-lifepo4-lithium-ion-battery-rel-rb300-lt","provider":"MEC","version":"1.0","type":"link"}
