Victron Energy VE.Bus BMS V2


The VE.Bus BMS V2 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.

Aux-in Input- 1A

Load Disconnect Output- Normally High, Source current limit 1A, Sink Current 0A (Output Free Floating)

Charge Disconnect Output- Normally High, Source current limit 1A, Sink Current 0A (Output free floating)

Pre-Alarm Output- Normally free floating, High (Vbat) in case of alarm, max 1A, (Not short circuit proof)

Remote terminals- Usage Modes to turn the system on or off:

  1. ON when the L and H terminal are interconnected (switch or relay contact)
  2. ON when the L terminal is pulled to battery minus (V<3.5 V)
  3. ON when the H terminal is high (2.9V < VH<Vbat)
  4. OFF in all other conditions 

VE.Bus Communication Port- Two RJ45 sockets to connect to all VE.Bus products
