BATTERY TOOLBOX · TEST & VALIDATE WORKFLOW

Test, benchmark, and qualify batteries — right on your bench.

Charge, discharge, cycle, and stress-test one or many batteries with fully customizable scenarios. Evaluate aging, validate batch consistency, and qualify new chemistries — without renting a battery test lab.

SOFTWARE

Otii + Otii Battery Toolbox

Otii Ace Pro turns into a programmable battery cycler. Build a discharge / idle / charge / idle sequence that matches your test plan, run it on as many batteries in parallel as your USB hub supports, and let it cycle indefinitely. Up to 25V / 5A per unit. No limit on the number of cycles, no limit on the number of batteries.

Work flow, end to end

STEP
01

Design your test sequence: discharge / idle / charge / idle

Build the cycle your test plan calls for. Each sequence can combine three state types: discharge (with optional sub-steps for stepped or pulsed loads), idle (rest periods between phases), and charge.

For the discharge state, choose constant current, constant power, or constant resistance — and set per-step durations, cut-off voltages, and pulse-width control.

The same sequence builder handles a simple one-step capacity test and a multi-state aging protocol.

STEP
02

Connect your batteries — one Otii Ace Pro per battery

Connect each battery to its own Otii Ace Pro and chain the units via a powered USB hub. There’s no software limit on how many you connect — your computer and hub set the practical ceiling.

Per unit you get up to 25V / 5A, with high accuracy load capability — enough for everything from coin cells to multi-cell Li-ion packs.

Whether you’re cycling 2 batteries or 20, the same sequence runs across all of them.

STEP
03

Run the cycles — for hours, weeks, or months

Start the run. Otii captures voltage, current, and capacity simultaneously across every connected unit, at high resolution, for as long as the test runs. The Otii application supports running multiple Otii Aces at the same time, so you see all batteries’ progress in one place.

For aging tests, set the cycle to repeat — there’s no software-imposed limit on the number of cycles. Walk away. Come back when done.
