We have a 12V 50ah LiFePo4 pack used for the solar road light in our company . As far as we know that more and more people are considering using LiFePo4 battery to replace traditional lead acid battery in the solar system storage . Also some other people are still hesitated about this because of LiFePo4's seemingly high cost .
If you make a calculation about cost/cycle for lead acid battery and LiFePo4 , you can see LiFePo4 is not expensive at all . I once made a comparison between LiFePo4 and lead acid in solar system use . If you are interested , please drop me a line .
Some pictures below for your reference : 12V 50AH LiFePo4 pack with BMS used for solar light.
We made a test for our 3.2V 10ah LiFePo4 single cell at 4C and the following is some general curves , please write to us if you are interested in a clear copy .
See the following small light weight vehicle .
It was converted from a bicycle and now powered by a 48V 20ah LiFePo4 battery pack .
We can also put some solar panels on the top/cap of the vehile , so the battery pack can be charged by solar power ! :)
