SHEN ZHEN LLT ELECTRONIC TECHNOLOGY CO,.LTD has established in 2012,is a professional Maker of multi-series bms and Power Management product in SHEN ZHEN City, Our product will be widely applied on powerful electric vehicle battery such as low and high speed vehicles ,solar backup power system ,inveter lithium battery ,Power station system of telcom station , solar street light power station , electric tool lithium battery pack and for other field . our company integrates research,development and manufacturing of various of high end PCB board for different lithium battery system based on different application purpose ,our technology team have more than 15 years development experience in average .also including design and product process design experience in our domestic lithium battery industry .
our company integrates research,development and manufacturing of various of high end PCB board for different lithium battery system based on different application purpose ,our technology team have more than 15 years development experience in average .also including design and product process design experience in our domestic lithium battery industry .
we developed and manufactured multi series BMS which can support max 175 series cells , and our BMS support multiple communication such as UART ,CAN ,RS485. also our BMS can have the active balance which support Max 5A balance current ,our some BMS can support Parrallel connection and master-slave management solution , as for big power consumption application field ,our BMS can provide even few hundreds Ah constant current etc .
Our excellent products are the result of the long-term hard work of our technical department
Featured Product series
Smart Bms with Various Type of Communication and excellent working performance
BMS With Bluetooth Function
BMS with Bluetooth function which will enable user to monitor SOH status of your Battery
BMS with Large Current
BMS can support max 300A discharge current with compact design for 12V Back up power application .
Multiple Communication
Smart BMS with elegant design which support UART ,RS485,CAN ,RS232 Communication .
bMS with Active Balance
BMS with active Balance will enable the battery system to keep excellent consistent by compensating power from higher voltage cell to lower cell .
Our BMS Protection Ability
Overcharge protection
When the voltage of any cell is higher than the set value of the cell overcharge voltage, and the duration reaches the cell overcharge delay, the system enters the overcharge protection state, the charging MOS will turn off, and the battery cannot be charged
Overdischarge protection
When the minimum cell voltage is lower than the set value of the over-discharge voltage of the cell, and the duration reaches the over-discharge delay of the cell, the system enters the over-discharge protection state, turns off the discharge MOS, and cannot discharge
Short Circuit protection
When the external short circuit occurred . and the BMS will protect the battery from suffering big current shock so as to provide the safety to the Battery system and consumer also ,once the External short removed , the BMS will recover Normally.
Over-Current Protection
When the discharge current exceeds the discharge Over-current protection current and the duration reaches the Over-current detection delay time, the system enters the discharge Over-current protection state and turns off the discharge MOS.
High temperature protection
When the NTC detects that the temperature of the battery cell surface is higher than the setting of high temperature protection value the charging or discharging MOSFET is turned off,and the high temperature protection will be removed later
Cultures and Missions
People-oriented management policy , always put our workers and clients on the first priority to respect them ,to help and support them
Director -MR Zhang
Becoming a leader in the lithium battery industry though our constant joint efforts ,Team spirits will be the most important for every person
Manger - MS zHOU
Always be honest even suffer some revenue loss ,afford society and environment protection responsibility ,share the same value towards our same goals !!!

Master-Slave Battery Management System
Master-Slave BMS
Distributed Master and Slave BMS system which was constructed with one Master BAU BMS and a series numbers of BMU BMU sampling board, high voltage board, switching power supply, Hall sensor, DC contactor, microswitch, power terminal, structural box and wiring harness, etc.; the characteristic is that the main control board Integrate with sampling board and other power devices to keep the system as a secondary architecture,it can be widely applied on commercial and household energy storage Battery system .such as Island off grid energy storage ,Micro-Grid Energy storage ,UPS power supply ,220V DC power supply system. Container back up power system etc
