??what is meant by battery management system . ??and does it mean the float and equalizing function not needed?
Thanks

Two main types of Lithium batteries:
Lithium ion: With some system modifications, lithium-ion batteries can be used with Morningstar MPPT controllers (TriStar and SunSaver). The battery bank must have a built-in or connected battery management system to monitor cell voltages. Further, the battery management system must NOT have an automatic full charge disconnect feature that breaks the controller connection to the battery. The controller will not operate without a power source. Finally, the controller needs to be programmed / set to disable the float and equalization stages so that current to maintain absorption voltage will be available at all times.
LiFePo4: Even though Morningstar controllers are designed for use with lead-acid batteries, lithium iron-phosphate batteries can be used successfully with programmable units. If using this battery technology, please check with the manufacturer for recommended set-points and current restrictions.
Any diversion function would require a separate Diversion Controller, such as the TS-PWM controller.
what is meant by battery managemwhat is the ent system ...and does it mean the float stage and the equalize stage are not used
