Five small green circuit boards with soldered components for 18650 cells

SMUGDESK

SMUGDESK 5Pcs 1S 12A 3.2V LiFePO4 BMS for 18650

SKU CH-6YJP-0HRQ6

Pack of five 1S protection boards rated at 12 A for 3.2 V LiFePO4 18650 cells

  • 5-pack bulk supply speeds up multi-project builds
  • 2 V LiFePO4 optimisation protects single-cell chemistry
  • 12 A continuous current powers daily low-power devices
  • Full safety suite stops overcharge, overdischarge, shorts and overcurrent
  • 18650 compatibility fits DIY packs, lights and monitors

5-Pack 1S 12A 3.2V LiFePO4 BMS

This set contains five single-series battery management boards built for 3.2 V lithium iron phosphate cells. Each board handles up to 12 A of continuous current and is intended for DIY battery packs, small power supplies and multi-project assembly work.

Makers building single-cell LiFePO4 packs

The boards suit hobbyists and engineers who need basic protection for individual 18650 LiFePO4 cells in lighting, monitoring gear or portable electronics. Projects that require multi-cell balancing, higher voltage stacks or integrated charging circuitry will need a different solution.

12 A continuous current rating

This figure defines the maximum steady load a single board can support without triggering its overcurrent cutoff. Match the expected draw of your device to this limit before committing the board to a build.

Questions about this item

What does the 12 A rating mean for my 18650 LiFePO4 cell?

It allows up to 12 A of continuous current, so the cell can power low-power devices steadily without tripping the over-current protection.

What voltage does the 3.2 V BMS manage and what protection limits does it enforce?

The board is made for a single 3.2 V LiFePO4 cell and cuts off on over-charge, over-discharge, short-circuit and over-current events.

Will this board fit a standard 18650 LiFePO4 cell?

Yes, it is designed specifically for 18650 LiFePO4 cells and mounts directly to the cell terminals for DIY packs.
