Precision 14.8V 8A Balance Li-ion Lithium Single 18650 Battery PCB Protection Board

Features:

  1. 3 period of over-current detection.
  2. Wide working temperature range and low current consumption.
  3. For each section of the battery voltage detection with high precision.
  4. Through the MOS tube can control the battery charging and discharging.
  5. This Lithium ion battery protection PCB protect single Lithium ion batteries. 8A continous current.
  6. Lithium ion protection is necessary, as Lithium ion will explode when they are shorted circuit or overcharged, and damaged when they are over discharged.
