About this replacement
Datalogic Mobile Scorpio — 3.7V Li-ion Replacement Battery (BS-215)
This is a 3.7V, 1800mAh Li-ion battery for the Datalogic Mobile Scorpio handheld barcode scanner. It fits scanners used in retail, warehouse, and logistics pick operations. Cross-references include BS-229, 127021590, 127021591, and 94ACC0054.
- Mobile Scorpio platform fit: The Mobile Scorpio draws from a single-cell 3.7V rail. All OEM part numbers listed above share the same cell format, connector pinout, and BMS handshake — the scanner's firmware reads pack state through the same communication line on each.
- Bench tested on actual hardware: We cycled this pack through simulated scan-burst loads, including rapid trigger pulls and simultaneous wireless polling. The BMS held cutoff thresholds correctly at both high-draw peaks and sustained mid-shift draw levels.
- First-shift preparation: After installing, seat the scanner in its cradle and run a full charge cycle before use. Scan trigger inrush current is highest when the cell is near minimum voltage — starting a shift on a partially charged new pack can cause false BMS trips on the first heavy burst sequence.
Cradle showing a charging error on a new pack
New packs sometimes ship at a storage charge — around 3.6–3.7V — which is below the cradle's expected start voltage for a full cycle. If the dock contact resistance is also elevated from dust or oxidation, the charger circuit can flag a fault before current transfer begins. Wipe the gold contacts on both the battery and the cradle dock with a dry cloth and reseat firmly. If the error clears, the pack will charge normally from that point.
Scanner loses wireless connection during rapid scan bursts
The Mobile Scorpio draws from the same cell for both the scan engine and the wireless radio simultaneously. During a rapid burst sequence, the combined inrush from the imager trigger and the radio transmit pulse can cause a brief voltage sag at the cell terminals. If the pack is below roughly 3.5V when this happens, the BMS may momentarily disconnect output to protect the cell — the radio drops first because it is the secondary load. Start each shift with a fully charged pack to keep the cell voltage above the sag threshold throughout the day.
