Cell Chemistry & BMS Daisy-Chain Architecture

Victron Lithium Battery Smart units use high-purity LiFePO4 chemistry with integrated cell balancing and Bluetooth monitoring. Unlike batteries with built-in internal contactors, these units offload safety switching to an external Victron BMS, maximizing system reliability and allowing massive surge currents.

The Victron Lithium Battery Smart delivers LiFePO4 chemistry for 12.8V and 25.6V modular storage banks (92% efficiency) with cycle life ratings of 2500 cycles at 80% DoD and 5000 cycles at 50% DoD:

• Charge & Discharge: 14.2V / 28.4V Absorption, 13.5V / 27.0V Float, 11.2V / 22.4V Cutoff, Bluetooth Smart.
• BMS Communications: M8 3-Pole Cables, Daisy-Chain Loop, Cell Balancing, smallBMS / Lynx.
• Environmental: Discharge: -20°C to +50°C, Charge: +5°C to +50°C, Store 1 Year, IP22 Rating.

Installation Rules & Commissioning

1. Initial Pre-Charging: Before configuring batteries in series or parallel banks, fully charge each unit individually to 100% SoC to synchronize cell balance.
2. BMS Loop Connection: Daisy-chain the BMS connection Male + female cable with M8 circular 3 pole connector, length 50cm cables from battery to battery, terminating the final loop connections into an external Victron BMS.
3. Low-Temperature Interlock: Never charge below freezing; enforce the Operating temperature Discharge: -20°C to +50°C Charge: +5°C to +50°C window using BMS charge disconnect signals.

Bluetooth Cell Monitoring & Charging Parameters

Every battery contains an active cell balancing circuit and Bluetooth radio:

• VictronConnect Telemetry: Wirelessly view individual cell voltages, battery temperature, and balancing activity, identifying minor cell deviations before alarms occur.
• Absorption & Float Voltages: Program all connected solar and AC chargers to Charge voltage Between 14V/28V and 14.4V/28.8V (14.2V/28.4V recommended) and **Float voltage 13.5V/27V**.
• Deep Discharge Cutoff: Protect the cells by programming downstream BatteryProtect switches to isolate DC loads prior to reaching End of discharge voltage 11.2V 11.2V 11.2V 11.2V 11.2V 11.2V 22.4V 22.4V.
• Long Cycle Life: Delivering 80% DoD 2500 cycles 70% DoD 3000 cycles 50% DoD 5000 cycles ensures decades of daily off-grid cycling.
• Storage & Casing: Adheres to Max storage time @ 25°C 1) 1 year, Storage temperature -45°C to +70°C, and Protection class IP 22.
