DALY BMS Li-ion 3S 12V 100A for 18650 Battery Pack

Build a protected 3-series lithium-ion battery pack with the DALY 3S 12V 100A Battery Management System. Designed for Li-ion battery packs, this BMS provides battery protection and cell balancing for compatible 3S configurations.

The board is listed as a common-port BMS with balancing, making it a practical component for battery-pack builders who need a protection system matched to their pack chemistry, series count, and current requirements.

Key Features

• 3S Li-ion configuration: Designed for three lithium-ion cells or cell groups connected in series.

• 100A continuous discharge rating: Manufacturer/reseller product specifications list 100A continuous discharge.

• Cell balancing: Includes a balancing function for the connected battery cells.

• Common-port design: Charge and discharge use the common port configuration.

• Battery protection: Product sources describe overcharge, over-discharge, over-current, and short-circuit protection.

• Battery pack application: Intended for compatible lithium-ion battery packs, including 18650-based configurations.

Technical Specifications

Important: The 12.6V charge voltage and 50A charge-current specifications are listed by retailer sources for this product variant. Confirm the exact board label and manufacturer specification before applying these limits to a battery pack.

Applications

• 3S lithium-ion battery pack assembly

• Compatible 18650 battery-pack projects

• Battery-powered equipment requiring a correctly matched 3S BMS

• DIY battery pack builds where cell balancing and protection are required

Compatibility Notes

This product is intended for 3S Li-ion battery packs. Do not select a BMS based only on the advertised “12V” label. Confirm the cell chemistry, series count, current requirement, and wiring configuration of your battery pack before purchase.

This listing does not claim compatibility with LiFePO4 packs, Bluetooth monitoring, or any specific device unless confirmed for the exact board variant.
