Estry Battery Replacement for AKAI EWI 5000 Solo 1ABTUR18650ZY01

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.
