Trying to learn something new every day!
I am waiting for the arrival of my 4- 200Ah LiFePo4 Cells they are new grade A cell direct from a manufacture.
I have been working on setting up a back board with all of the connection and testing points on it and am waiting
for the cells to complete the installation.
In preparation I have a few questions regarding the testing and setting up for these cells:
#1 Using a 150Watt Digital Battery Capacity Tester that I purchased of of Ali Express do I need to test the capacity of each cell
or will a test of the battery pack be sufficient?
I am a bit confused by this based on Wills video on the use of this Capacity Tester.
#2 After receiving the cells I believe I should check there voltage and verify that they are at the same state of charge. Then is it best
to configure them in parallel then let them sit for a couple of days to balance out?
#3 After this should I reassemble the cells into a series connection of 12Volts add my BMS and deplete the battery down to 12 volts
and then check the status of each cell. Once this is complete using my DC desktop power supply should I then raise the voltage of
the pack to 13.3 volts?
#4 Based on Wills suggestions he recommends using a upper voltage limit of 13.3 Volts and a Flood Voltage of 13.2 Volts with a disconnect
of 12 volts for solar applications. I have a EPEVER Tracer controller and will set the high and low voltages there. The issue now is do I have to
set a flood voltage level as these batteries do not need I believe a flood level voltage?
Thank you for your time and I will await your replies.
