Compact MOSFET battery management module — low-resistance MOSFET switches (3.7V compatible) that deliver a stable 15A output while minimizing heat. Designed for space-constrained 18650 and polymer battery packs, it keeps thermals efficient during sustained use. Key benefits Reliable 15A power delivery: low Rds(on) MOSFETs provide stable current with lower conduction losses, reducing heat and improving run time. Broad compatibility: optimized for 3.7V single-cell lithium systems and small multi-cell 18650/polymers packs used in portable and embedded applications. Space-efficient design: compact footprint for tight battery compartments and portable products. Robust operation across temperature extremes: components rated to operate between 20°C and 85°C without performance degradation. Long life and durability: military-grade components ensure more than 10,000 charge/discharge cycles for demanding, long-lived applications. Easy integration: standardized interfaces simplify installation and accelerate system-level integration. Who this is for Electronics engineers and system integrators building battery management into prototypes and production units. Manufacturers of portable power tools and industrial devices needing compact, high-drain battery switching. Designers of automotive accessories, solar storage subsystems, and portable medical equipment requiring stable power and protection from voltage fluctuations. Typical use scenarios Portable medical device: provides stable 15A supply in a compact pack while keeping temperatures low and meeting long cycle-life requirements. Mobile power and solar storage: protects inverters and storage modules from voltage swings during charging, discharging, or variable environmental conditions. Power tools and equipment: compact integration into 18650 or LiPo packs to support high-drain motors and frequent cycle use.
