A high current cells with good capacity.











Very good discharge curves with perfect tracking and nearly constant capacity up to 20A







At 30A the cell temperature must not be above 80°C, it goes over the limit here, but I do first see it after I have stopped the discharge, because the temperature measure is not instantaneous.















Conclusion

This is a very good high current battery, it has fairly high capacity and can deliver a lot of current.
