Security

These are the best high-discharge LiFePO4 cells I've found. I recommend them to everyone.
I use these in a device that needs short bursts of 15C. They have been extremely reliable.
These BAK cells are the best choice for any high-amperage application.
The discharge curve of these LiFePO4 cells is incredibly flat, providing steady power.
The 40pcs pack is an incredible deal for anyone needing a lot of high-discharge cells.
