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.
