【1 LiFePO4 battery = 2 lead-acid batteriesThe Power Queen 12.8V OTCB Smart LiFePO4 100Ah battery offers the same usable capacity as two 12V 100Ah lead-acid batteries and supports series and parallel connections to build a safe battery system with less wiring and lower costs. The LiFePO4 battery weighs only 11.27 kg, 1/6 the weight and 1/3 the size of two 12V 100Ah lead-acid batteries.
-
【4000-15000+ cycle times && 10 years lifespanThe Power Queen LiFePO4 battery supports 4,000-15,000+ cycle times under various depths of discharge (DOD). This is 20-50 times the 200-300+ cycle times of a lead-acid battery. LiFePO4 solar batteries are durable and long-lasting. With a lifespan of 10 years, they need to be replaced less frequently than a typical lead-acid battery with a lifespan of 2-3 years. This reduces the overall cost over the long term and also requires less maintenance.
-
【100% depth of discharge &&; Shutdown at low temperaturesThe OTCB Smart Battery offers 100% depth of discharge, while a typical lead-acid battery only has 50%. This means the OTCB Smart Battery can deliver twice the usable energy of a lead-acid battery with the same nominal capacity. The OTCB Battery features built-in low-temperature charge protection, which automatically stops the charging process when the cell temperature drops below 0°C.
