With cell balancing, but without BMS: 12,8V LFP batteries for light duty applications
In applications were excessive discharge (to less than 11V), overcharge (to more than 15V) or excessive charge/discharge current will
never occur, 12,8V batteries with cell balancing only may be used.
Please note that these batteries are not
suitable for series or parallel connection.
Notes:
1. A Battery Protect module (see www.victronenergy.com) may be used to prevent excessive discharge.
2. The current draw of inverters and inverter/chargers is often still significant (0,1A or more) after low voltage shutdown. The
remaining stand-by current will therefore damage the battery if the inverters or inverter/chargers are left connected to the
battery after low voltage shutdown during a long period of time.
With cell balancing and interface to connect to a Victron BMS: 12,8V LFP batteries for heavy duty applications and
parallel/series connection
The batteries with suffix BMS are fitted with integrated Balancing, Temperature and Voltage control (BTV). Up to ten batteries can be
paralleled and up to four batteries can be series connected (BTV’s are simply daisy-chained) so that a 48V battery bank of up to 2000Ah
can be assembled. The daisy-chained BTV’s must be connected to a battery management system (BMS).
Battery Management System (BMS)
The BMS connects to the BTV’s and its essential functions are:
1. Disconnect or shut down the load whenever the voltage of a battery cell falls to less than 2,5V.
2. Stop the charging process whenever the voltage of a battery cell increases to more than 4,2V.
3. Shut down the system whenever the temperature of a cell exceeds 50 °C.
More features may be included: see the individual BMS datasheets.
