Multiplus 2 48/3000 GX Lifepo4 Battery values

Hi.


I got 2 5kwh lifepo4 batteries and at the moment I am struggeling with translation of values names inside of batteries manual and victron value names.


Those values are inside of the battery manual:

1. Overvoltage disconnect voltage -----57.6V

2. Charging limit voltage ----58.4V

3. Overvoltage reconnect voltage -----53.5V

4. Balanced charging voltage -----56V

5. Increase the charging voltage

6. Float charging voltage -----54.0V

7. Boost reconnects charging voltage

8. Low voltage reconnect voltage -----48V

9. Low voltage warning Reconnect the voltage -----48V

10. Low voltage warning voltage -----45V

11. Low voltage disconnect voltage -----43.2V

12. Discharge limit voltage -----40V


Can you help me which values I should enter in VEconfigure with ESS to which victron field?


Thanks in advance.

Probably the low voltage warning level of 45v

What I have interpreted so far from the values in the documentation would be the following Victron settings. Are these okay or do I break the batteries with it?


DC input low shut-down:43.2V

DC input low restart:48V

DC input low pre-alarm:45V

Absorption voltage:56V

Float voltage:54V

Charge current:50A

Sustain voltage:40V

Hi @ovaron

Maybe your batteries are in this list?.. https://www.victronenergy.com/live/battery_compatibility:start

Even if not you may learn a bit from reading through what's involved with some of them.
