DALY BMS Li-ion 13S 48V 30A BMS Battery Management System for 18650 Battery Pack Balanced Charging Board

The DALY BMS Li-ion 13S 48V 30A is a high-performance solution designed for 18650 lithium-ion battery packs. Built with balance protection and advanced PCB design, this 13S 48V BMS in Pakistan ensures maximum safety and efficiency by offering overcharge, over-discharge, overcurrent, short-circuit, and temperature protection. With a fixed 13S configuration, it is strictly intended for Li-ion battery packs and cannot be used with LiFePO4, Li-Metal, or LTO batteries. Whether for DIY energy storage projects or professional applications, this waterproof and reliable BMS guarantees stability, long battery life, and consistent performance.

Features

• Overcharge & Over-discharge Protection: Stops charging at 4.25V per cell and cuts discharge at 3.0V for safety and longer battery life.
• Temperature Protection: Shuts down discharge above 70℃ and works safely down to -20℃.
• Short Circuit Protection: Instantly disconnects the battery pack during faults to prevent hazards.

Applications

• Solar power systems and RVs
• Electric bikes, scooters, and skateboards
• Camping boats and portable power tools
• Lawn mowers and household energy storage systems
