Very high current batteries from Keeppower with good capacity.












The discharge curves tracks perfectly and capacity is nearly independent of current.







At 30A the batteries get rather warm, my logfile says peak temperature was 84°C after I stopped.













Conclusion

These cells are designed for very high current draw, but when going near 30A a temperature cutout may be needed.

It is very good batteries.
