This 48V 100Ah LiFePO4 battery provides 5.12kWh of energy for compatible off-grid, solar and backup power systems. Bluetooth monitoring and CAN/RS485 communication support battery status monitoring and system integration in compatible 48V power installations.
Built around a 51.2V 100Ah LiFePO4 platform, the battery can be expanded in parallel for projects that need additional storage capacity without increasing the nominal system voltage.

With 5,120Wh of stored energy, this 48V lithium battery is designed for compatible off-grid power systems, solar installations and backup power projects built around a 51.2V battery platform.
The single-battery configuration provides 100Ah of capacity and can be expanded in parallel when additional energy storage is required.
Bluetooth monitoring provides convenient access to battery information during installation, commissioning and routine system checks. A compatible monitoring interface can display key operating data without requiring direct access to the battery enclosure.
CAN and RS485 communication allow the battery to exchange operating information with compatible external equipment and coordinated battery systems. This is useful for projects where battery data needs to be shared with an inverter, system controller or monitoring platform.
Communication compatibility should be confirmed against the inverter, controller and protocol version before installation. CAN and RS485 interfaces do not automatically guarantee protocol compatibility with every third-party device.
For compatible projects, CAN communication can be used to exchange battery information with supported Victron equipment. This can make battery operating data available to the connected energy-management and monitoring system.
Victron compatibility depends on the battery communication protocol, inverter or GX device, firmware and system configuration. Confirm the required communication profile before commissioning the system.
For larger off-grid, solar and backup power projects, identical batteries can be connected in parallel to increase total storage capacity while maintaining a 51.2V nominal system voltage.
With supported battery communication enabled, the reference configuration supports up to 16 batteries in parallel. A fully expanded 16-battery bank provides 1,600Ah and 81.92kWh of nominal stored energy.
Without communication, the reference configuration supports up to four batteries in parallel. Series connection is not supported.
Parallel batteries should use the same model, capacity, BMS configuration and state of charge. Use appropriately sized busbars, balanced cables, individual branch protection and system-level disconnect protection.
The integrated 200A Battery Management System monitors voltage, current and temperature during charging and discharging and provides protection when operating conditions move outside programmed limits.
The reference specification lists a maximum continuous charge current of 100A and maximum continuous discharge current of 100A, with discharge up to 200A for two minutes and 600A for one second.
The BMS monitors cell temperature and automatically stops charging when the cells fall below the permitted charging range. Charging becomes available again after the cells return to the specified recovery temperature.
This configuration does not include active self-heating. Low-temperature protection disconnects charging or discharging when required but does not actively heat the battery cells.
The battery uses an SPCC steel enclosure measuring approximately 19.88 × 12.32 × 9.25 inches and weighs approximately 97.44 lb. The enclosure is intended for upright installation with adequate clearance for terminals, communication ports, cabling and service access.
Measure the available installation space before specifying the battery for an equipment enclosure, electrical room or off-grid power system.
Use charging equipment configured for the battery's LiFePO4 CC/CV charging profile. The reference charge voltage is 57.6V ± 0.8V, with a recommended charging current of approximately 20A.
Do not connect solar panels, a generator or an AC source directly to the battery. Charging equipment must regulate voltage and current within the specified battery limits.
This 51.2V 100Ah battery is intended primarily for compatible stationary and off-grid deep-cycle power systems where communication, monitoring and parallel expansion are useful.
