New Lithium NG Batteries Discharge Rates

I saw the news on the new Victron Smart Lithium NG batteries and was comparing the data in the available data sheet with the existing Smart Lithium batteries. One thing that stood out is the change in maximum charging and discharge rates. Is it correct that those rates are indeed reduced in the NG batteries? Below is an example.

Current Smart Lithium 25.6V 200Ah battery

  • Max Continuous Discharge Current: 400A
  • Recommended Continuous Discharge Current: <=200A
  • Max Charge Current: 400A
  • Recommended Charge Current: <=100A

New Smart Lithium NG 25.6V 200Ah battery

  • Max Continuous Discharge Current: 200A
  • Recommended Continuous Discharge Current: Unavailable
  • Max Continuous Charge Current: 100A
  • Recommended Charge Current: Unavailable

If those figures are correct, what is limiting the new batteries to lower performance levels than the existing batteries? Is it the shunt that is included in the NG batteries?

Look a bit closer at the resistance difference.

VIR is a strong relationship.

Thanks for that insight. I hadn't tried to understand the impact of resistance.
