Hi!
I came across an installation that uses the above charger for LFP batteries. Would you recommend this for LFPs? I don't think it is a wise choice as although it has repeated absorption called equalize but only settable for 0-4-8-12 hours which is not ideal for LFP (which would need it once every 7 days or so). Would you agree?
thanks

Can I have a quick Yes/No/"Rather not" response from Victron staff? thanks
As you can read in the manual:
https://www.victronenergy.com/upload/documents/Manual-TI02170-EN.pdf
the re-equalisation time is 30 minutes, so that's pretty usefull.
both voltages can be adjusted, so I don't see any problems.
quote:
Assuming that the battery is discharged, the Titan charger starts charging in the boost-charge mode. In this mode the battery is charged until the battery voltage reaches the boost voltage. At this point the battery is charged to approximately 80% of its maximum capacity.
This is the end of the boost-charge mode and the Titan charger automatically switches to the equalizecharge mode. During the equalize-charge mode the charging voltage stays the same as the boost voltage but the charge current slowly decreases. The duration of this mode is pre-selectable to 4, 8 or 12 hours.
The standard time of the equalize-mode is 4 hours. After this time the Titan charger automatically switches into the float-charge mode. In the float-charge mode the charge voltage changes into the float voltage and the charge current continues to decrease.
This mode lasts for 20 hours. After the float-charge mode the charger returns to the equalize-charge mode for 30 minutes, this is to compensate for the normal leakage or self discharge of the battery.
Hi!
thanks for taking time the respond. Actually this is one of my two concearns:
1.)
In the TG terminology absorption seems to be 'equalize'. In case of the TG it is minimum 4 hours instead of the recommended 1 hour for smart LFPs.
2.) Secondly, from the doc: "After the float-charge mode the charger returns to the equalize-charge mode for 30 minutes, this is to compensate for the normal leakage or self discharge of the battery. "
This is done opposed to the recommended 7 days rebalancing period that the Multis are set to.
For most systems this is fine, set the voltage a little bit lower if you are concerned.
