Feature highlights common to all models:
• Specifically designed for use with our Lithium Battery 12,8V & 25,6 V Smart battery range.
• Communicates directly with the lithium battery via the battery’s M8 circular connector cables.
• Protects the lithium battery cells from overvoltage, under voltage or a too low or high temperature by
turning off loads or charge sources via its “load disconnect” and “charge disconnect“ terminals.
• Up to 5 paralleled batteries, or paralleled battery series strings can be connected to the BMS.
System Voltages:
• The SmallBMS, VE.Bus BMS V2, VE.Bus BMS and the Lynx Smart BMS can connect to a 12, 24 or 48 V system.
• The other BMS models can only connect to a 12 V system.
System connection:
• The SmallBMS, VE.Bus BMS V2 or VE.Bus BMS require that all loads and charge sources are directly
connected to the battery. The BMS turns them off in case of a battery cell voltage or temperature alarm via
the “load disconnect” and “charge disconnect“ terminals.
• The Lynx Smart BMS has a safety DC contactor. It disconnects the system from the battery or battery bank
in case of a battery cell voltage or temperature alarm and can be used as a main system on/off switch.
• The Smart BMS 12/200 and the BMS 12/200 have a dedicated system output to which both loads, and
chargers can be connected. The system output will disconnect in case of a battery cell voltage or
temperature alarm.
Alternator:
• The Smart BMS CL 12/100, Smart BMS 12/200 and the BMS 12/200 have a dedicated alternator input. This
input wil activate when the alternator is running, and the starter battery has reached a sufficient voltage. It
will current limit the alternator supply and blocks reverse current from the lithium battery into the starter
battery. It disconnects in case of a battery cell voltage or temperature alarm.
• The Lynx Smart BMS has an alternator ATC mode, so additional alternator protection is not needed.
Pre-alarm options:
• All models have a pre-alarm output with exception of the BMS 12/200.
Remote on/off options:
• All models have a “remote on/off” terminal with the exception of the VE.Bus BMS.
• The “Smart” BMS models can also be turned on and off via Bluetooth and the VictronConnect app.
Bluetooth and the VictronConnect app
• All “Smart” BMS models are equipped with Bluetooth and can be monitored, operated, and configured via
the Victron Connect app. The Lynx Smart BMS also supports Bluetooth live data advertisement.
Battery monitor
• The Lynx Smart BMS has a full-featured built-in battery monitor.
Communication options:
• The VE.Bus BMS and VE Bus BMS V2 can directly control a VE.Bus inverter or inverter/charger in case of a
battery cell undervoltage, overvoltage or temperature alarm.
• The VE.Bus BMS V2 and Lynx Smart BMS can be used for communication or control via a GX device and can
control compatible inverter/chargers and solar chargers via DVCC control without the need to use the load
and/or charger disconnect terminals.
• The Lynx Smart BMS can monitor up to 4 Lynx distributor modules.
Optional accessories:
• The VictronConnect app (free download) for “Smart” BMS modules.
• Pair of M8 circular connector 3 pole cables, to extend the battery BMS cables.
• Cable for Smart BMS CL 12/100 to MultiPlus.
• VE.Direct non inverting remote on/off cable.
• Inverting remote on-off cable.
• Non inverting remote on-off cable.
System design recommendations:
• The
SmallBMS
for 12 , 24 or 48 V systems without inverter/chargers.
• The
VE.Bus BMS V2
for 12, 24 or 48 V systems with inverter/chargers and a GX device
• The
VE.Bus BMS
for 12, 24 or 48 V systems with inverter/chargers.
• The
Lynx Smart BMS
for 12, 24 or 48 V systems with digital integration and with the need to have a safety
relay to disconnect DC loads and/or inverters or inverter/chargers, like is the case in yachts or recreational
vehicles.
• The
Smart BMS CL 12/100
for 12 V systems with an alternator.
• The
Smart BMS 12/200
– for 12 V systems with an alternator and DC loads and an inverter or
inverter/charger.
• The
BMS 12/200
for 12 V systems with an alternator and DC loads but without an inverter/charger. Be
aware that this model is end-of-life and will switch battery positive instead of the negative. Consider using
a Smart BMS 12/200 instead.
