Description

The Victron BatteryProtect 48V 100A disconnects the battery from non-essential loads before it is completely discharged, protecting the bank from damaging deep discharge on 48V systems. It suits larger marine, off-grid and industrial installations where a low-voltage load disconnect is needed.

The unit is set up with a seven-segment LED display, which shows the chosen engage and disengage threshold at a glance. A dedicated Li-ion setting lets the device be controlled by a VE.Bus BMS, and it can also serve as a charge interrupter between a charger and a lithium battery.

Solid-state MOSFET switching makes the BatteryProtect ignition proof, with no relays and no sparks. Delayed alarm, load-disconnect and reconnect timing avoids nuisance tripping during brief voltage dips.

PRODUCT DETAILS

What does the BatteryProtect do?
It automatically disconnects non-essential loads when the 48V battery voltage drops to a preset level, preventing deep discharge that would damage the battery.
Does this model have Bluetooth?
No. This is the standard 48V BatteryProtect, set up with a seven-segment LED display. For Bluetooth programming via the VictronConnect app, choose the Smart BatteryProtect 48V.
Can I use it with lithium batteries?
Yes. It has a dedicated Li-ion setting and can be controlled by a VE.Bus BMS. It can also act as a charge interrupter between a charger and a lithium battery.
What is the operating voltage range?
24 to 64 V. Loads are also disconnected by over-voltage protection if the DC voltage exceeds 64 V.
Can it handle current from a charger as well as to a load?
No. The BatteryProtect is a uni-directional device and is not designed for reverse currents from charging sources. Current flows from the battery terminal to the load terminal only.
