This is a high capacity and high current battery.
The discharge curves has good tracking and capacity only drops slowly with load. The battery has trouble at 30A due to heat.
The battery will get warm at high current.
At 20A it was very close to a termination due to temperature.
At 30A I had to stop due to temperature. The battery reached 86°C after I terminated.
This battery has very good performance for both capacity and current.
