Intelligent YKN-BMS4S BMS(Battery Management System) Lithium battery LifePO4 12V 4series Battery Packs protection board

Features
YKN-BMS4S is a protection board designed anddeveloped for 4-series battery packs, suitable forsmall energy storage batteries, street lights, 12V  lithium batteries, and otherproducts; The product adopts an integrated intelli-gent lithium battery management chip, supporting RS485,CAN, and Bluetooth communication.Someparameters can be flexibly adjusted through theupper computer according to customer needs.

Function
Supports 4 series of lithium iron phosphate battery packs.
Integrate hardware protection functions, such as overvoltage, low voltage, overcurent, high temperature, low temperature, shor
Circuit protection,etc:Inteligent balancing function: it can set the starting voltage and starting voltage diference for balancing, and can choose
between charging balancing or static balancing;
Supports 4-way battery cell temperature detection and 1-way power temperature detection;
Supports communication such as Bluetooth,RS485, CAN, etc;
Reserve heating and buzzer functionsLow power consumption: When the BlMS is in a stationary state, it can enter a sleep state to reduce power consumptionBMS supports series and parallel connection of battery packs.
