PylonTech 4.8 kWh US5000B Lithium-ion battery

Building a home, bach or off-grid battery bank? The Pylontech US5000B is a 4.8 kWh, 48 V LiFePO4 battery module that slots straight into a 19" rack and talks directly to your Victron system over CAN bus — so your inverter and chargers always know exactly what the battery is doing. Start with one module and stack up to sixteen as your power needs grow.

At a glance

• Depth of discharge: up to 95%
• Built-in BMS with over-discharge, over-charge, over-current and high/low-temperature protection
• Form factor: 19" rack-mountable, self-cooling (no fans)
• Communication: CAN bus / RS485 — works seamlessly with Victron inverters and GX devices
• Expandable: connect up to 16 modules in parallel for more capacity and power

US5000B features

Communicates seamlessly with Victron inverters via CAN bus.

• Built-in soft-start function able to reduce current strike when inverter need to start from the battery
• Dual active protection on the BMS level
• Automatic address setting when connecting in multi-group
• Support wakeup by 5~12V signal from RJ45 port
• Support upgrade battery module from the upper controller via CAN or RS485 communication
• Enable 95% depth of discharge, available for the inverter which completely follows Pylontech latest protocol to operate.
• The module is non-toxic, non-pollution and environmentally friendly
• The cathode material is made from LiFePO4 with safety performance and long cycle life.
• The battery management system (BMS) has protection functions including over-discharge, over-charge, over-current and high/low temperature
• The system can automatically manage the charge and discharge state and balance the voltage of each cell.
• Flexible configuration, multiple battery modules can be in parallel for expanding capacity and power
• Adopted self-cooling mode rapidly reduced system entire noise
• The module has less self-discharge, up to 6 months without charging it on the shelf, no memory effect, and excellent performance of shallow charge and discharge.
• Small size and lightweight. Standard 19-inch embedded designed module is comfortable for installation and maintenance

Stacking & compatibility

The US5000B works alongside Pylontech's other 48 V modules. For the same type of module, always use the latest production unit as the master:

• Mixture using master-battery priority: US5000 > UP5000 / US3000C / US2000C > US3000 / US2000
• Master battery (1st): US5000
• Slave 2nd–8th: US5000 / UP5000 / US3000C / US2000C / US3000 / US2000
• Slave 9th–16th: US5000 / UP5000 / US3000C / US2000C

Complete your system

• Victron MultiPlus-II inverter/charger — the 48 V partner for off-grid and hybrid setups.
• Cerbo GX MK2 — monitor state of charge and your whole system from your phone via the free VRM app.
• Add the matching Pylontech 48 V cable pack and a Class T fuse to wire it in safely.
