Description

Protection module for 3.7V - 5A Lithium-Ion battery packs, designed to ensure safety and efficient management of lithium batteries in 1S configuration. It features protection against overcharge, over-discharge, overcurrent and short circuit, ensuring long life and reliable performance for battery packs.

This BMS (Battery Management System) module is designed to safely protect 3.7V Li-ion cells in 1S configuration, in particular 18650 batteries. Thanks to its 3 built-in MOSFETs, the module offers protection against overcharge (above 4.25V), over-discharge (below 2.45V), short circuit and overcurrent up to 5A.

Compact and easy to install, with dimensions of 38×7.5×2 mm, it is ideal for applications such as power banks, portable devices and DIY projects. This BMS ensures safe and optimal battery management, extending battery life and preventing potential damage.

The module can be used both with solder-tab batteries and standard batteries, via a dedicated battery holder available separately (see related products).
Battery connection
  • B-: battery- connection
  • P+: positive terminal for current output from the battery (to power a device) and also for current input when the battery is charging.
  • P-: negative terminal for current output from the battery and also for current input during charging.
