Lithium-iron-phosphate LiFePO4 19"RACK battery, capacity 50Ah, 48V, 3U

Advantages of lithium-iron-phosphate batteries:

• LiFePO4 batteries can be charged at a much higher current than gel or AGM batteries. models, which significantly shortens the charging time
• Half the weight and delivers more power than traditional lead-acid, gel or AGM batteries
• They have very high efficiency (about 95%) and low internal resistance, which allows fast charging with low energy losses
• They provide 100% rated power utilization regardless of discharge current.
• Life of lithium-iron-phosphate batteries is approximately 3000 cycles (full charge and discharge) or more depending on battery discharge
• They can operate in a very wide temperature range. They maintain their effectiveness both at -10 and 45 degrees Celsius
. • LiFePO4 batteries are non-toxic, non-polluting and contain no rare earth metals, making them environmentally friendly
