Victron Energy VE.Bus BMS | BMS300200000

$164.69 CAD
Shipping calculated at checkout.

The VE.Bus BMS is a Battery Management System (BMS) designed to interface with and protect a single, or multiple Victron Lithium Battery Smart 12,8V & 25,6V (LiFePO4 or LFP) in systems that have Victron inverters or inverter/chargers with VE.Bus communication.

It monitors and protects the batteries against over voltage and under voltage of any individual cell, and also over temperature or under temperature conditions.

Warranty

This product is covered by a 5 year limited warranty

Victron Energy lithium LiFePO4 BMS selection guide

Victron Energy VE.Bus BMS | BMS300200000

Protects each individual cell of a Victron lithium iron phosphate (LiFePO4 or LFP) battery

Each individual cell of a LiFePO4 battery must be protected against over voltage, under voltage and over temperature. Victron LiFePO4 batteries have integrated Balancing, Temperature and Voltage control (acronym: BTV) and connect to the VE.Bus BMS with two M8 circular connector cord sets.
The BTVs of several batteries can be daisy chained. Up to five batteries can be paralleled and up to four batteries can be series connected (BTVs are simply daisy-chained) so that a 48V battery bank of up to 1500Ah can be assembled. Please see our LiFePO4 battery documentation for details.
The BMS will:
- shut down or disconnect loads in case of imminent cell under voltage,
- reduce charge current in case of imminent cell overvoltage or over temperature (VE.Bus products only, see below), and
- shut down or disconnect battery chargers in case of imminent cell overvoltage or over temperature.

Protects 12V, 24V and 48V systems

The operating voltage range of the BMS: 9 to 70V DC.

Communicates with all VE.Bus products

The VE.Bus BMS connects to a MultiPlus, Quattro or Phoenix inverter with a standard RJ45 UTP cable.

Other products, without VE.Bus, can be controlled as shown below:

Load Disconnect

The Load Disconnect output is normally high and becomes free floating in case of imminent cell under voltage (default 3,1V/cell, adjustable on the battery between 2,85V and 3,15V per cell).
Maximum current: 2A.
The Load Disconnect output can be used to control
- the remote on/off of a load, and/or
- the remote on/off of an electronic load switch (Battery Protect)

Pre-alarm

The pre-alarm output is normally free floating and becomes high in case of imminent cell under voltage (default 3,1V/cell, adjustable on the battery between 2,85V and 3,15V per cell).
Maximum current: 1A (not short circuit protected).
The minimum delay between pre-alarm and load disconnect is 30 seconds.

Charge Disconnect

The Charge Disconnect output is normally high and becomes free floating in case of imminent cell over voltage or over temperature. Maximum current: 10mA.
The Charge Disconnect output can be used to control
- the remote on/off of a charger and/or
- a Cyrix-Li-Charge relay and/or
- a Cyrix-Li-ct Battery Combiner

LED indicators

- Enabled (blue): VE.Bus products are enabled.
- Cell>4V or temperature (red): charge disconnect output low because of imminent cell over voltage or over temperature.
- Cell>2,8V (blue): load disconnect output high.
