Each battery uses a built-in 200A BMS with low-temperature protection that limits charging below 32°F and discharging below -4°F, adding a safeguard in cold-weather conditions without manual oversight. Each unit weighs just 55.1 lb in a compact 15.12\" x 7.64\" x 9.96\" case that's 57% lighter than a comparable 12V 200Ah lead-acid battery and fits common 4D and 8D battery boxes. Grade-A prismatic LiFePO4 cells support 5000+ cycles at 80% depth of discharge, and the pair can be wired in series, parallel, or both — expandable up to a 4S4P, 61.44kWh system as your power needs grow.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eUp to 7680Wh of Lithium Power in a Two-Battery Pack\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis package includes two Core Mini batteries, each delivering 3840Wh, for 7680Wh of combined lithium storage. That capacity suits essential RV, marine, and off-grid loads — such as a refrigerator and small appliances — when paired with a properly sized inverter. Actual runtime depends on your specific loads and inverter, so heavier draws like air conditioning will draw down capacity faster.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eLow-Temperature Protection for Cold-Weather Use\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe integrated 200A battery management system guards against overcharge, over-discharge, over-current, and short circuits, and self-balances cell voltage. Its low-temperature cut-off limits charging below 32°F (0°C) and use below -4°F (-20°C), helping protect the cells during winter travel and cold storage.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eLightweight, Compact Build That Fits 4D and 8D Battery Boxes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eAt 55.1 lb each, these batteries are manageable for one person to lift and install. The compact case is roughly 31% more space-efficient than many other 12V 300Ah LiFePO4 batteries and fits a range of enclosures, including 4D and 8D battery boxes, leaving more room for clean wiring and easier maintenance. An IP65 rating adds protection against dust and low-pressure water.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eGrade-A LiFePO4 Cells Built for 5000+ Cycles\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eEach battery uses Grade-A prismatic lithium iron phosphate cells rated for 5000+ cycles at 80% depth of discharge — long-term durability that far outlasts traditional lead-acid. Both batteries are backed by a 5-year prorated material and workmanship warranty and carry MSDS, UN38.3, FCC, CE, PSE, RCM, RoHS, and UKCA certifications.\u003c\/p\u003e\n\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; gap: 24px; margin: 32px 0;\"\u003e\n\u003cdiv style=\"flex: 1 1 320px;\"\u003e\u003cimg alt=\"Renogy Core Mini 12V 300Ah LiFePO4 battery for RV van marine and off-grid power systems\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0761\/5781\/2888\/files\/RBT12300LFP-M-_04__86535.1741082619.1280.1280_db91afb5-9d6e-4e01-89f0-cd58a864e7aa.webp?v=1780707613\" width=\"1000\" height=\"1000\" style=\"width: 100%; height: auto; border-radius: 8px;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 320px;\"\u003e\n\u003cp\u003eTwo 12.8V 300Ah lithium batteries deliver 7680Wh of combined deep-cycle capacity for RVs, vans, marine builds, and home backup.
