Direct replacement battery

The KingSener BTY-M48 is a 15.2V 50WH lithium-ion pack built to replace part numbers BTY-M48 and 4ICP5/41/119. It fits MECHREVO S1 series laptops with i5 8250U or i7 8550U processors and MSI PS42 Prestige models including 8RA, 8RB and 8RC variants. The black cell assembly arrives new and ready to install.

Steady discharge profile

Rated at 3390mAh, the pack delivers its 50 watt-hour capacity across a full work session rather than only in short bursts. Internal cell matching keeps voltage stable as the charge drops from 100 percent toward empty. The chemistry sustains typical office and media loads without the sharp voltage sag seen in aged originals.

Low heat and silent operation

With no moving parts the battery adds no audible noise to the chassis. Normal charge and discharge cycles keep cell temperature close to ambient, so the laptop’s own cooling system is not stressed. Power draw during recharge follows the host controller’s standard profile, avoiding extra load on the AC adapter.

Questions about this item

Does the 15.2 V 50 Wh BTY-M48 run hotter than the original pack during all-day use?

The 15.2 V 50 Wh lithium-ion cell matches the original voltage and capacity, so thermal behaviour under continuous load remains equivalent to the factory battery.

Will the BTY-M48 fit my MECHREVO S1-C1 without any extra brackets or cables?

The BTY-M48 is a direct replacement for part numbers BTY-M48 and 4ICP5/41/119, so it seats in the existing bay using the original connectors.

Can I keep using my MSI PS42 8RB Prestige charger with the new BTY-M48 installed?

Yes, the 15.2 V 50 Wh pack works with the standard PS42 charger because it restores the same voltage and capacity the laptop expects.
