Lithium Iron Phosphate (LiFePO4) Batteries for Solar, RV and Backup
LiFePO4 batteries deliver 3,000–6,000 charge cycles, use 100% of their rated capacity and weigh about half as much as lead-acid—which is why they have become the standard for off-grid solar, RVs, boats and home battery backup. Blue Sky Yard carries deep-cycle lithium batteries from Dakota Lithium, Rich Solar, EG4 and SunGold Power in 12V, 24V and 48V, including server-rack batteries that stack into 30 kWh+ banks.
Match the battery to the system
- 12V 100–300Ah – RVs, vans, trolling motors, small cabins.
- 24V – Mid-size cabins and workshops running 24V inverters.
- 48V rack & wall batteries (5–15 kWh each) – Whole-home solar with EG4, SunGold and similar 48V inverters; closed-loop communication keeps charging accurate.
Check the battery's continuous discharge rating against your inverter, and confirm low-temperature charging protection if the battery lives in an unheated space. Need help building a bank? Call (888) 835-6051.
