Profile & emulate

Characterize battery and replay its discharge curve. 

  • Sleep and active mode modeling
  • 25 nA–5 A range, 0.05% accuracy
  • Compare batteries side-by-side
  • Import/export discharge profiles
  • Emulate cells in series or parallel
  • Runs on Ace Pro or Arc Pro
Estimate battery life

Predict your device’s battery life before you commit and ship.

  • Combine real device profiles + battery profiles
  • Compare battery life scenarios 
  • Test “what if” scenarios in seconds
  • Use your created discharge profiles or manufacturers
Test & validate

Test, validate and cycle batteries under your actual load profile.

  • Discharge / idle / charge / idle, repeat – build your custom test sequence
  • Constant current, power, or resistance
  • Unlimited number of cycles
  • Scale units to your batch size
  • Runs on Ace Pro only

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?

No. Licenses are tied to your Qoitech account. Activate on up to N machines, move between lab PCs as your setup changes. You can also share with or move your license to your colleague.

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.
