Ikusi 2303692 Crane Remote Control Replacement Battery 4.8V 750mAh

Ikusi 2303692 / BT06K — 4.8V Ni-MH Replacement Battery

This is a 4.8V 750mAh Ni-MH battery for Ikusi crane and hoist remote controls. It fits the 2303692, ATEX transmitters, RAD-TF and RAD-TS transmitter series, plus over 16 additional Ikusi remote models. The 2303692 and BT06K part numbers both reference this same cell pack.

• RAD-TF, RAD-TS, and ATEX transmitter fit: These transmitter lines share the same 4.8V four-cell Ni-MH pack configuration, connector pinout, and physical housing slot. The BMS handshake is passive — no proprietary authentication chip — so a matched voltage and chemistry swap seats and charges correctly across all listed models.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge on a 4.8V Ni-MH charger, confirmed stable cutoff voltage at the top of charge, and verified no voltage sag under the solenoid activation pulse typical of Ikusi crane remote relay circuits.
• Infrequent-use charging schedule: Ikusi crane remotes often sit idle for weeks between jobs. Ni-MH cells self-discharge at roughly 1–2% per day unprotected. If the remote has been shelved for more than three weeks, connect it to the charger for a full cycle before putting it back into service — cells left fully discharged for extended periods can develop voltage depression that reduces recoverable capacity.

Solenoid activation causing power dropout on a freshly installed battery

When the crane remote triggers a relay or solenoid, the inrush current spike can briefly pull the pack voltage below the remote's low-voltage cutoff threshold. This looks like the remote cutting out or rebooting the moment you press a control button. It happens most often when the new battery has been sitting at storage voltage — around 4.2–4.3V — rather than at a full 4.8V charge. Run a full charge cycle before first use and the pack will hold voltage through the activation pulse.

Remote shows low-battery indicator immediately after new cell install

Ni-MH cells ship in a partial storage state, typically 50–60% capacity. The remote's voltage monitor reads this as a low or critical battery condition. This is not a fault with the cell — it is expected behaviour for an uncharged pack. Place the remote on its charger and allow a full charge cycle to complete. The low-battery warning will clear once the pack reaches its nominal 4.8V resting voltage.
