Direct replacement for AKAI EWI 5000

This lithium battery pack replaces the original 1ABTUR18650ZY01 cell in the AKAI EWI 5000 and 5000 Solo wind controllers. It delivers a 3.7 V nominal voltage with a rated capacity of 3000 mAh and is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards. The single-cell unit measures 66.3 x 21.0 x 18.5 mm and weighs 74.2 g.

Cool and quiet operation

The pack integrates overcharge, over-discharge, over-voltage and short-circuit protection circuits that keep temperatures low during typical rehearsal or performance sessions. No active cooling is required and the cell runs silently, so it adds no audible noise to the instrument’s signal path. Power draw follows the controller’s normal operating profile without spikes.

Steady output through long sets

Under continuous play the protection circuitry maintains stable voltage delivery while preventing deep discharge, so the battery sustains its rated 12.58 Wh capacity across extended gigs. The chemistry resists capacity fade when cycled daily, and the safety certifications confirm reliable behaviour under sustained load rather than only in short bursts.

Questions about this item

How do I install this 66.3 x 21.0 x 18.5 mm battery into my EWI 5000, and what step do people often get wrong?

Open the battery compartment, insert the pack matching the polarity markings, and secure the cover; the step users miss is verifying the connector clicks fully into place before closing the door.

What maintenance or replacement will this 3400 mAh lithium pack need later?

No scheduled maintenance is required; when run-time drops noticeably after many charge cycles, replace the pack with another 3.7 V 18650 cell matching the original 1ABTUR18650ZY01 part number.

What limit appears first during a long continuous performance with this 12.58 Wh battery?

The 3400 mAh capacity sets the play-time ceiling; expect the voltage to sag near the end of a full discharge, signalling the need to recharge before the next session.
