Direct Replacement for Sunmi Handhelds

This Estry battery replaces the original SMBP001 and SM-INR18650M26-1S2P packs used in the Sunmi P1, WS920, V2, W6900 and V1S terminals. It is built for technicians and operators who need a drop-in lithium cell without modification.

Single-Cell 3.7 V Chemistry Limits Runtime

The pack delivers 3.7 V from a 1S2P lithium configuration rated at 5200 mAh and 19.24 Wh. Capacity and voltage are fixed by the cell chemistry, so operating time scales directly with the terminal's current draw and cannot be extended by the battery itself.

5200 mAh Capacity Decides Fit

The 5200 mAh rating is the sole figure that determines whether this pack matches the original runtime spec. Verify the part numbers SMBP001 or SM-INR18650M26-1S2P on the existing battery before ordering.

Questions about this item

Which capacity should I pick — the 5000mAh spec or the 5200mAh spec?

The 5200mAh figure is the manufacturer-rated capacity for this replacement pack; the 5000mAh value appears in the generic specification table.

What does the 19.24Wh rating tell me about actual run-time in a Sunmi P1?

At 3.7V the pack stores 19.24Wh; real run-time depends on the device’s power draw, so divide that watt-hour figure by the terminal’s average watts to estimate hours.

Does the 3.7V lithium pack use a standard connector that fits the WS920 V2 and W6900 V1S?

Yes — it is built to the exact SMBP001 and SM-INR18650M26-1S2P part numbers, so the connector and pin-out match the original battery in those models.
