1s BMS 3.7v

The 1S 3.7V BMS (Battery Management System) is a compact and essential protection circuit designed for single-cell lithium-ion or lithium polymer (LiPo) batteries. It ensures the safe operation and longevity of the battery by monitoring key parameters during charging and discharging cycles.

Key Features:

• Overcharge Protection
  Prevents the battery from charging beyond the safe voltage limit (typically 4.2V), which can lead to overheating or damage.

• Over-discharge Protection
  Stops the battery from discharging below the safe threshold (usually around 2.5V–3.0V), which helps preserve battery health and prevents deep discharge damage.

• Overcurrent & Short-circuit Protection
  Automatically cuts off the output if the current exceeds safe levels or in the event of a short circuit, protecting both the battery and connected devices.

• Auto Recovery Function
  Many 1S BMS modules include an auto-recovery feature, allowing the system to resume normal operation once conditions return to safe levels.
