Common questions

Can I try Otii Battery Toolbox before I buy?

Yes — if you have Otii hardware (Arc Pro or Ace Pro), you can start a free trial and use the full Battery Toolbox on your own bench. If you don’t have Otii hardware yet, book a demo and we’ll walk you through the toolbox on real equipment.

Which Otii instrument do I need?

Profiling and emulation as well as battery life estimation work on both Otii Arc Pro and Otii Ace Pro. Battery Validation (multi-battery cycling with high precision) requires Otii Ace Pro. See the compatibility table above.

Are the licenses node-locked?

An Otii Toolbox license is associated with a user, not a specific piece of hardware. The license can be shared; a user can share it with another user, but it can only be used by one user at a time.

What happens to my data if I cancel?

Your recorded data and exported profiles stay on your machines — Otii stores files locally. You lose access to licensed features but not to anything you’ve already captured.

Two ways to start.

Already have an Otii Arc Pro or Ace Pro? Start the Battery Toolbox free trial. New to Otii? Book a demo and we’ll walk you through your use case.
