Victron Smart BatteryProtect 48V-100A — 48V Auto Low-Voltage Disconnect with Bluetooth
Couldn't load pickup availability
The Victron Smart BatteryProtect 48V-100A is the 48V version of the BatteryProtect family — 100A load capacity at 48V (4800W), automatic low-voltage disconnect, built-in Bluetooth. The right pick for 48V residential ESS, telecom remote sites, and large off-grid systems where over-discharge protection is critical.
Why 48V load protection matters
48V battery banks are typically large and expensive — a single LiFePO4 48V/100Ah rack is $1500–$2500. Over-discharging shortens the cycle life dramatically and, on lithium banks, can permanently damage the BMS. The BatteryProtect adds an inexpensive insurance layer on top of the BMS, especially important for systems that may run unattended.
What 100A at 48V protects
- 4800W AC inverter circuit (MultiPlus-II 48/3000 + small accessory loads)
- Multi-phase MultiPlus-II essential-loads subpanel
- Telecom equipment rack (multi-server, multi-router)
- Off-grid home essentials circuit (kitchen + lighting + electronics)
- EV charger circuit at moderate amperage
Why the Smart BatteryProtect 48V-100A
- 100A load capacity at 48V — 4800W circuit protection
- 48V native — designed specifically for 48V systems
- Built-in Bluetooth — configure thresholds, view stats, get alerts
- Programmable thresholds — tuned for 48V LiFePO4, AGM, Gel, Flooded
- VE.Smart Networking — takes battery data from SmartShunt for accurate decisions
