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 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
Dimensions

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
- WatchMon-CORE requires a IsoMon3, the use of a CMUConnect will damage the WatchMon-CORE 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
Connecting to Inverter / Charger using CANbus

Powering WatchMon CORE 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)
