Direct replacement for Mechrevo S1

This lithium-ion battery carries the BTY-M48 part number and matches the 4ICP5/41/119 reference used in several Mechrevo chassis. It is intended for owners of the S1, S1-C1 and PS42 8RB Prestige laptops who need a new power source. The pack delivers 15.2 volts and 50 watt-hours of capacity in a black housing. It ships as a single unit ready for installation.

Black lithium-ion pack

The battery uses a conventional internal connector that aligns with the motherboard socket on the compatible Mechrevo models. Its rigid black casing fits the existing battery bay without modification. No additional cables or brackets are required for day-to-day use. The 12-month warranty period reflects the supplier's confidence in the cell quality.

Verify your exact model

Confirm that your laptop appears in the supported list — S1, S1-C1 or PS42 8RB Prestige — and that the original battery carries the 4ICP5/41/119 or BTY-M48 code. Different configurations of the same chassis may use a different voltage or capacity. Buyers who need a higher watt-hour rating or a different form factor should look for an alternative pack.
