Are the 18650 LG Li-ion battery cells good to use on a ebike. I currently have 60 of them that were recycled from used laptops and they are in very good condition and working perfectly. I am going to build a 24v 26ah pack from them. Will it perform similar to a lifepo4 battery. Will I be able to pull a constant current draw of about 20amp from it without causing any issues. In other words how will it perform in comparison to a lifepo4?
This is the specs:
