Introductory Post for BesTech BMS and electronics.
I had previously considered these for my systems because of the advanced features, functions and capabilities. The price point is fairly good but I chose to go with Chargery BMS. The Chargery's are fine but when you start to get into several packs within a bank, things become unwieldy for management and interaction. I have more or less outgrown what the Chargery's can do for me. As my Midnite & Samlex gear do MODBUS (sorry I cannot provide Samlex Modbus info, I have a developer NDA) the need to have the battery packs be able to interact with the devices is more important than ever.... even moreso as I am moving beyond 4 battery packs in the LFP bank.
The Bestech BMS' have various models for wide variety of uses. I am at present revisiting the HS-015 but there are others worthy of consideration. Please Note that these are not "discount value BMS", they are more in line with TinyBMS and higher level systems.

The HS-015 :
100A~1000A Battery Management System,Programmable BMS with CANBus, RS485, RS232, UART Communication protocol-BesTech Power Co., Ltd
Please note that I am very seriously considering these units shown above and am looking into my options. IF (likely) I get these and start testing & installation, I will of course write a review of sorts for fellow members. TBH, I am going to push them hard to the point of almost abuse to make sure they do what I need & want.
IF there are any members here who have Bestech BMS', please feel free to Chime In with your thoughts on the product.
Thanks & Have a Great Day.

• Balancing Wire Port – battery pack balancing sensing wires, 1st wire can be used as ON/OFF or reset
• 4 X External Temp. Sensors – 8 Pins connector for 4 x external sensors
• LCD/Bluetooth/WiFi Module for external connections
• GPIO Port – 12 Pins for e-switch/ignition key, external systems such as SOC LED, alarm buzzer… the definition of GPIO socket as the figure below.
• Communication Port: CANBus, RS485, RS232, UART
• Relay Port: For external relay, external heating/cooling system
Communication Protocols
BMS supports different communication protocols, HS006 integrated with 1x RS485, 1x RS232, 1x CANBus, 1x UART, all communications are isolated except for UART, the default baud rate used in current communication implementation is set as 19200KBPS, contact BesTech support for different baud rate setup, such as 9600K or others.
P.S. RS485, RS232, CAN communications can be used simultaneously.
BMS communicates with windows PC utility thru UART/RS485/RS232/CAN protocol, customer need purchase BesTech programming tool separately to do the programming and reading for all parameters.
