About this replacement
ELCA MITO-VETTA / MAGO-EVO Series — 3.7V Li-Polymer Replacement Battery (0401BA000311)
This is a 3.7V 1250mAh lithium-polymer battery for ELCA crane remote controls, including the MITO-VETTA, MAGO-EVO, VETTA, and EVO series. It replaces OEM part number 0401BA000311 directly. The cell measures 59.70 × 37.10 × 6.30mm and fits the original compartment without modification.
- MITO-VETTA and MAGO-EVO platform fit: These remotes share the same 3.7V single-cell architecture, connector pinout, and BMS handshake protocol across the VETTA and EVO families, which is why one cell covers all listed models.
- Bench tested on actual hardware: We cycled this cell through full charge and discharge on the MITO-VETTA remote, confirmed BMS recognition at power-on, and verified solenoid activation did not cause a voltage dropout under load.
- Monthly charge during crane downtime: Crane remotes often sit unused for weeks. A Li-polymer cell discharged below 2.5V trips BMS lockout — the remote will appear dead even with a charger connected. Charge the battery once a month during any idle period to stay above that threshold.
BMS lockout after the MITO-VETTA sits unused for months
Li-polymer cells self-discharge at roughly 2–3% per month. After a long shutdown — common on seasonal or intermittent crane sites — the cell voltage can fall below 2.5V, which triggers the BMS protection circuit and blocks all charge current. The remote shows no signs of life even when plugged in. Connect the charger for 30 minutes before assuming the battery is faulty; some chargers apply a trickle current that brings the cell back above the BMS threshold and allows normal charging to resume.
Remote showing low-battery warning immediately after fitting a new cell
Replacement cells ship at storage voltage — typically 3.6–3.7V — not at full charge. The ELCA remote interprets this as a partially depleted battery and triggers the low-battery indicator straight away. This is not a fault with the cell. Charge the battery fully before first use; the warning clears once the cell reaches its nominal full-charge voltage of approximately 4.2V.
