Battery Management system
The BMS connects to 12,8V Victron LiFePO4 (LFP) batteries. Up to 5 batteries may be connected in parallel.
Can be used as a system on/off switch.
Starter battery Protection
This function is similar to that of a Cyrix Battery Combiner or Argo FET Battery Isolator. Current can flow to the LFP battery only if the input voltage (= voltage
on the starter battery) exceeds 13V.
Additionaly current cannot flow back from the LFP battery to the starter battery, thus preventing eventual damage to the LFP battery due to excessive
Alternator and battery protection
The input current is electronically limited to approximately 90% of the fuse rating. A 100A fuse, for example, will therefore limit the input current to
Choosing the right fuse will:
a. Protect the LFP battery against excessive charge current (important in case of a low capacity LFP battery).
b. Protect the alternator against overload in case of a high capacity LFP battery bank (most 12V alternators will overheat and fail if running at maximum
output during more than 5 minutes).
Load/battery charger output-input (Power Port SYSTEM+)
This Power Port can be used to either charge or discharge the LFP battery (i.e. via a charger, an inverter or inverter/charger) with a maximum continuous
current of 200A in both directions.
Can also be used as a load output, thus DC loads can be connected directly to this port. The port is short-circuit protected with a peak discharge current of
The Smart BMS will make sure that the battery discharge will cut-off in case of imminent cell under voltage.
The Smart BMS will enable charging through this port, but no charge algorithm can be applied internally.
Li-ion battery protection
Excessive input voltage and transients are regulated down to a safe level.
The Smart BMS will stop charging in case of cell over voltage or over temperature. It has three outputs, similar to the smallBMS:
Load Disconnect output
The Load output is normally high and becomes free floating in case of imminent cell under voltage (default 2,8V/cell, adjustable on the battery between 2,6V
and 2,8V per cell). Maximum current: 10mA. The Load output can be used to control the remote on/off input of a Battery Protect, inverter, DC-DC converter or
The pre-alarm output can be used as warning when the battery voltage is low and it will trip shortly before the Load Disconnect output is disabled due to cell
The pre-alarm output may be used to drive a relay, LED or Buzzer. It can be configured as continuous or intermittent signal.
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 output
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 is not suitable to power an inductive load such as a relay coil. The Charge disconnect output can be used to control: the
remote on/off of a charger, a Cyrix-Li-Charge relay, a Cyrix-Li-ct Battery Combiner.
(Note: in some cases an interface cable will be needed, please see the manual.)
Remote on/off input
The remote on/off input controls the charging via the alternator. When off, charging via the alternator is disabled, while the BMS functionality will remain
active allowing any loads and chargers to continue working regardless of the state of the remote input.
When “system on/off switch” is enabled via VictronConnect, the BMS functionality will also be disabled.
It consists of two terminals: Remote L and Remote H. A remote on-off switch or relay contact can be connected between H and L.
Alternatively, terminal H can be switched to battery plus, or terminal L can be switched to battery minus
No relays but MOSFET switches,
and therefore, no sparks.
Victron Energy Limited Warranty Policy
Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the end user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead acid batteries; 2 years from date of purchase by the end user, with a maximum of 30 months from the Victron Energy invoice date, Lithium-ion batteries; 3 years from date of purchase by the end user. In addition to this proof of correct battery usage is required when making a battery warranty claim.
During this period, Victron Energy will, at its option, repair or replace the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation and re‐installation. This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like:
• Reverse of battery polarity.
• Inadequate connection.
• Mechanical shock or deformation.
• Contact with liquid or oxidation by condensation.
• Use in inappropriate environment (dust, corrosive vapor, humidity, high temperature, biological infestation...).
• Breakage or damage due to lightning.
• Connection terminals and screws destroyed or other damages, like overheat, due to insufficient tightening.
• For any electronical breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state ofthe internal control diode and of the inputs/output X and Y capacitors determine the warranty.
This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone else than Victron Energy or one of its authorized Qualified Service Partners. In order to qualify for the warranty, the product must not be disassembled or modified.
Repair or replacement are our sole remedies and Victron Energy shall not be liable for damages, whether direct, incidental,special, or consequential, even caused by negligence or fault.
Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers in performing warranty repairs and building replacement products. If Victron Energy repairs or replaces a part of a product, its warranty term is not extended. In case of replacement the new component has a warranty of 6 months, without effect on the initial warranty period. All remedies and the measure for damages are limited to the above. Victron Energy shall in no event be liable for consequential, incidental, contingent orspecial damages, even if having been advised of the probability of such damages. Any and all other warranties expressed or implied arising by law, course of dealing, course of performance, usage of trade or otherwise, including but not limited to implied warranties of merchantability and fitness for a particular purpose, are limited in duration to a period of two (2) years from the date of purchase.
