## Long description

Replacement rechargeable battery pack Cameron Sino NR18650 MH1-4S1P-SC is designed for use in compatible Xiaomi VIOMI V3, V2 Pro and JX37 cordless vacuum cleaners. The module uses four 18650 cells arranged in a 4S1P configuration to deliver the voltage and capacity required by the original power module. It is intended as a spare or replacement to restore operating time and maintain cordless cleaning performance when the factory pack is worn or no longer holds an adequate charge.
Advantages
This battery pack provides a direct-fit replacement option that matches the physical configuration and electrical characteristics expected by the compatible vacuum models. Using established 18650 cell technology in a 4S1P layout ensures a predictable voltage output and consistent discharge behavior under normal vacuum loads. The pack is supplied pre-assembled and ready for installation, reducing the time and technical work required for replacement. It is suitable for users seeking to recover runtime and restore the cleaner’s cordless operation without replacing the entire appliance.

How to use
Before installation, ensure the vacuum is powered off and disconnected from any charger. Remove the old battery pack following the device manufacturer’s service instructions or a compatible disassembly guide; observe electrostatic discharge precautions and avoid shorting pack terminals. Install the replacement pack into the vacuum housing, reconnect any plugs or terminals as originally fitted, and secure the housing fasteners. Charge the new battery fully prior to first use using the original charger or a charger specified for the vacuum to balance the pack and establish proper state of charge.
Usage recommendations
To optimize battery life and performance, charge the pack after each deep discharge and avoid storing the vacuum for extended periods in a fully discharged state. Operate the vacuum within the manufacturer’s recommended temperature range and use the original charger when possible. If you are not experienced with electronic repairs or battery handling, seek professional assistance to replace the pack to avoid damage or risk.
