Battery Protection Board 4S 100A 12.8V Accessory for Lithium Iron Phosphate Batteries

Feature: 1. Balance Light: Part of the battery pack exceeds 3.40V, and the other part of the battery pack is lower than 3 40V, the light is on. If the voltage of 4 groups exceeds 3 40V or the voltage of 4 groups is lower than 3 39V, the light is off. 2. Safer Working: The contact switch has low voltage protection, which promises stable restoring and output. 3. Broad Utility: Also allows for application as for car starter and promoter, very reliable and practical. 4. Simple to Use: When power switch is turned on, the switch is turned off, and the output starts, very easy. 5. Easy to Install: Light in weight and compact in size, the easy wiring largely simplifies the installation.
