We use Lithium Iron Phosphate Battery instead of Lead Acid Battery applied in Solar Powered Aviation Obstruction Light.There are two main reasons as follows.

1.Lithium Iron Phosphate Battery has Lighter weight.Weight of 12V 12Ah Lead Acid battery is 3.45kg while Weight of 12V 12Ah Lithium Iron Phosphate Battery is 1.35kg.

2.Cycles of Lithium Iron Phosphate Battery is about 5 times than Lead Acid Battery.Cycles of Lithium Iron Phosphate Battery is about 2000 timesCycles of Lead Acid Battery is about 400 times.That is to say,service life of Lithium Iron Phosphate Battery is longer a lot than Lead Acid battery.
