Overview

• BMS to suit LiFePO4, Lithium-Ion or custom chemistry
• User configurable parameters and control logic
• Configurable 30vdc 5A relay (i.e. remote circuit breaker trip, contactor or fan)
• Additional inputs / outputs via Expansion Board purchased separately 
• Compatible with all Expansion Board (Series 1, 2, or 3) 
• Clock with backup battery data logging of key metrics for 10 years 
• Firmware upgrades via USB 
• 4 stage display of State of Charge (SoC%) 
• External ambient temperature sensor 
• Easy to use pluggable screw-terminal connectors 
• With distributed cell monitors capable of 28 Ah / day balancing adjustment for each cell 
• Link to ShuntMon with 500A or 1000A power rating
• Compatible with MultiMon (MM8)

Remote Communication

• WiFi connectivity (normal, disabled, or read only) 
• CANbus Opto-Insulated to remote Charger / Inverter equipment 
• Future feature to connecting to Cloud Portal via MQTT (secure link)

Improvements

• Easier to use layout than previous models
• Bigger DC-DC (6W) supporting 8-65V supply
• Cell Monitor port (aka CMU) now with its own external fully isolated communication module named "IsoMon3" that can link to LongMon, BlockMon and LeafMon
• CMU and Shunt serial ports have a different number of pins to avoid confusion
• New on-board Relay (30vdc 5a relay) making it easier for DIY wiring

Optional Expansion Board (Series 3) Details

• 3 x Mechanical 30Vdc 5A relay outputs
• 3 x Solid state relay SSR 65vdc 5A isolated modules outputs
• 2 x Isolated inputs 5-65vdc sensor channel
• 2 x ADC 0-5vdc (future development option)
• 1 x RS485 Serial port (future development option)
• 1 x External Addressable LED (future development option)
• Compatible with all supervisors

Connecting LongMons to CMU Serial Port

• Best to number the first cells from Negative in increasing order
• Hi speed CMU serial  with the isolation moved to separate IsoMon3 for single cell monitors      (i.e. LongMon, BlockMon and LeafMon)
• CMUConnect and IsoMon3 are NOT interchangeable 
• WatchMonCORE requires a IsoMon3, the use of a CMUConnect will damage the WatchMonCORE product

Follow the commission and trouble shooting guides to install:-

Connecting to ShuntMon

CMU and Shunt serial ports have a different number of pins to avoid damage / confusion

Powering WatchMonCORE supply

For High Voltage battery pack systems best to adopt a Fully isolated DC-DC to provide a supply voltage of either 12v or 24v depending on application.

• Built-in 8v to 65v DC-DC supply (non isolated)
• Consumes ~1.7W with WiFi enabled (typical 48v battery budget 1Ah / day)
