The 2025 Xiaomi 14.4V lithium battery (2P4S configuration) offers capacities ranging from 5200mAh to 12800mAh, designed for devices like the Viomi S9, Lydsto R1, and Roadmi Eve Plus. It features advanced thermal management, EVE-cell technology, and compliance with UL/CE certifications. This battery prioritizes longevity, safety, and high energy density, making it ideal for power-intensive applications.

How Does the 2P4S Configuration Enhance Performance?
The 2P4S setup merges parallel cells for increased capacity and series cells for voltage stability. This reduces internal resistance, minimizes heat generation, and extends runtime by 15-20% compared to traditional Li-ion packs. It also enables balanced energy distribution, critical for high-drain devices like electric scooters.
In the 2P4S architecture，two cells connected in parallel double the current capacity while maintaining voltage levels. Four of these paired cells are then linked in series to achieve the required 14.4V output. This hybrid approach allows simultaneous optimization of both ampere-hours and voltage regulation – a critical advantage for devices with fluctuating power demands. For example, the Lydsto R1 scooter benefits from sustained torque during hill climbs while maintaining efficient energy use on flat terrain.
