2. Introduction
2.1. Description
Victron Energy Lithium Smart batteries are Lithium Iron Phosphate (LiFePO4 or LFP) batteries available with a nominal voltage of 12.8V or 25.6V in various capacities.
This is the safest of the mainstream lithium battery types and is the battery chemistry of choice for very demanding applications.
2.2. Features
Integrated cell balancing, temperature and voltage control system
The battery has an integrated balancing, temperature and voltage control system (BTV) that must be connected to an external battery management system (BMS). The BTV monitors each individual battery cell, balances the cell voltages and generates an alarm signal in case of high or low cell voltage or in case of high or low cell temperature. This alarm signal is received by the BMS (must be purchased separately, see the The BMS models chapter for an overview of available BMS models and functionality), which then switches off the loads and/or chargers accordingly.
Setup, monitoring and control via Bluetooth and the VictronConnect App
Battery setup, configuration and monitoring is done entirely via Bluetooth and the VictronConnect app.
View battery parameters such as cell status, voltages and temperature in real-time, configure the battery limits or update the battery firmware. Please see the Battery settings and configuration via VictronConnect chapter for details.
For details, please see the Battery settings and configuration via VictronConnect chapter and get to know about the VictronConnect app and its functions. The VictronConnect manual can be downloaded from the product page.
Up to 20 batteries can be series, parallel or series/parallel connected
Victron Smart Lithium batteries can be connected in series, parallel and series/parallel so that a battery bank can be built for system voltages of 12V, 24V or 48V. The maximum number of batteries in one system is 20, which results in a maximum energy storage of 84kWh in a 12V system and up to 102kWh in a 24V and 48V system.
Other features
