ELCA MIRAGE-M Crane Remote Compatible Battery 7.4V 2600mAh

ELCA MIRAGE-M / BRAVO-M — 7.4V Li-ion Replacement Battery (LI-TE)

This 7.4V 2600mAh Li-ion battery replaces the OEM LI-TE cell in ELCA MIRAGE-M and BRAVO-M wireless crane remote controls. It fits the transmitter units used to operate overhead cranes and hoist systems in industrial environments. Voltage and capacity match the original exactly — no modifications needed to fit the housing.

• MIRAGE-M and BRAVO-M platform: Both remotes share the same LI-TE battery bay, connector orientation, and 7.4V power rail. The BMS handshake requirements are identical across the two units, so one cell fits both without any firmware or connector differences to work around.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a MIRAGE-M transmitter. The BMS accepted the cell cleanly, voltage held steady through solenoid activation events, and the protection circuit tripped correctly at the low-voltage cutoff threshold — no false dropouts under normal relay switching loads.
• Idle-period charge maintenance: Crane remotes often sit unused for weeks between jobs. Charge this battery once a month during any idle period — Li-ion cells left below 2.5V per cell can enter BMS lockout and refuse to respond to a charger even when reconnected.

Solenoid activation causing power dropout on the MIRAGE-M

When a crane remote triggers a solenoid or relay, the inrush current spike can briefly drag cell voltage below the BMS protection threshold. A partially discharged or degraded battery is far more vulnerable to this — internal resistance climbs as capacity fades, which amplifies the voltage sag during that inrush event. A fresh, fully charged 2600mAh cell keeps internal resistance low enough to absorb the spike without tripping the protection circuit. If dropouts persist with a new cell at full charge, check the solenoid wiring and connector contacts before assuming a battery fault.

Replacement Li-ion cells ship at storage voltage — typically around 3.6V to 3.8V per cell, not at full charge. The MIRAGE-M reads this as a low-battery state and flags it on the transmitter display straight away. This is not a faulty cell. Connect the battery to the OEM charger and bring it to a full 8.4V before use — the low-battery indicator will clear once the cell reaches operating charge. Do not put the remote into service on a storage-voltage cell, particularly where E-stop response speed matters.
