• Cycle life: 250 cycles to 70% (4A charge and 22A discharge, pause at 70°C, resume at 50°C)

These cells are a test of a high performance protection, it has lover resistance and can handle higher current than usual protections.











The discharge chart shows a very good cell and the new protetion means less voltage drop due to protection





This current trips the protection after some time and the cell will not get hot.











I did not adjust my test to handle higher protection currents, the trip point is somewhere above 20A





Conclusion

This battery has lower voltage drops than other protected batteries with the same cell. For anything in the 3A up to 7A - 10A this cell is a very good option for a protected battery.
