Daly Lifepo4 4S 12V 20A Battery Management System Circuit is a 4-cell in Series 12V circuit power tool mostly used for solar lighting. It is designed for lithium Batteries for charging and protection from overcharge, and Over-discharge. The battery protection board, as the name suggests battery protection board is mainly rechargeable and protects the integrated circuit board.

Lithium batteries (rechargeable type) need protection, which is determined by their own characteristics. As the Orange lithium battery, its material determines itself can not be overcharged, overcharged, overcurrent, short circuit, or ultra-high temperature charge and discharge, so lithium battery lithium components will always follow A protective plate with a sampling resistor, and a current fuse.


  1. State of charge calculations.
  2. Cell over-voltage and under-voltage protection.
  3. Intelligent battery balancing (passive).
  4. Fully sealed waterproof technology, with waterproof, dustproof, shockproof, anti-squeezing, and other protective functions
