01 — About

What it does

The 3S Type-C BMS is a 3-cell lithium battery management system with charging and protection functions. It manages series-connected 18650 cells with balancing, overcharge protection, and Type-C charging input.

Key features

  • 3-cell series management (11.1V nominal, 12.6V max)
  • Type-C charging input
  • Cell balancing for equal charge distribution
  • Overcharge protection at 4.25V per cell
  • Overdischarge protection at 2.5V per cell
  • Overcurrent/short-circuit protection
  • Temperature protection (on some models)

Good to know

  • Verify cell voltages are balanced before first connection
  • Use cells with similar capacity and internal resistance
  • BMS protects but does not replace proper charging practices
  • Check continuous current rating meets your application needs
  • Some BMS modules require activation after protection triggers
  • Never bypass BMS protection – risk of fire/explosion
