Hello folks,
It has been a long time. Got tired of harvesting (more like looking for cheap source of laptop batteries) ans stopped.
I found a source that has 20-30 Valence 12V 130Ah LiFePo4 packs. The issue is that their condition is unknown, they are used but no capacity measurement was done. They were purchased in 2017 and have been left on their own.
How would one go about testing the health and capacity of such high Ah packs?
Idea is to buy as many as I can and create 5s - 60V storage system. Maybe but a loud of Batterium monitors.
SOS
Read they there's damage under 2.5V much like NMC based Li-ion. Can they be recovered? though might be better to use then with care
