The smallBMS NG with pre---alarm is an allinone Battery Management System (BMS) for Victron

Lithium NG batteries (not to be confused with the lithium smart batteries without NG). These batteries

are Lithium Iron Phosphate (LiFePO

4

) batteries and are available in 12.8V, 25.6V and 51.2V in various

capacities. They can be connected in series, parallel, or a combination of both to create battery banks

for system voltages of 12V, 24V, or 48V. A maximum of 50 batteries can be used when configuring a

bank with 12V or 24V batteries, while up to 25 batteries can be used with 48V batteries. This allows for

a maximum energy storage capacity of 192 kWh with 12V batteries, up to 384 kWh with 24V batteries,

and 128 kWh with 48V batteries. For comprehensive details about these batteries, visit the Victron

Lithium NG battery product page.

The smallBMS NG is a simple and cost-effective alternative to the VE.Bus BMS NG, but lacks a VE.Bus

interface and is therefore not suitable for use with VE.Bus MultiPlus and Quattro inverter/chargers.

: Controls the remote on/off input , of aBatteryProtect, InvertersDC-

DC converter, or other loads with remote on/off functionality.Due to its maximum output

current of 1A, it can even control a highcurrent relay or a contactor.Note that a - non-inverting

or inverting on/off cable may be required, please consult the manual.

Configurable discharge floor:Configurable discharge floor:

Sets the minimum SoC to prevent excessive discharge while

ensuring enough energy for self-discharge. A low SoC warning is triggered in VictronConnect,

activating the prealarm output when the discharge floor is near. -A low SoC alarm is triggered

when the discharge floor is reached, and the BMS immediately deactivates the ATD output,

effectively shutting off any loads it controls.
