There is a lot to be said for just setting the absorption voltage to 14.4V or 14.6V, and then stop charging once the battery reaches that voltage! In short, zero (or short) absorb time.
Float voltage LiFePo4 battery
Hello, I have a LiFePo4 12V battery and a Victron smartsolar MPPT 100/50 regulator. battery présents recommends 14.6V. However default setting of LiFePo4 is at 14.2V for absorption voltage and 13.5V for float voltage. Should I change both absorption and float voltage to 14.6V? Appreciate in advance your help.
what is the absorption rate for my 280amh LiFepo4 battery (see pdf-attached…
No absorption, equilization or float volts or time is needed for lifepo4 batteries. If you can''t turn those settings off, then I''d set absorption to 14.2v, and equalization and float to 12.8v (assuming a 12v battery - double these for a 24v battery). According to your manual, both the bulk voltage and max cutoff voltage should be set to …

Then set absorption to 14v, float to 13.8v. Absorption time to 1 hr. Charge current to 40A. (20A each) Inverter tab, set disconnect voltage to 10.8, reconnect to 12.4v, low volt pre alarm 11.6v All of this is outlined in the multi manual and the info available from
MultiPlus charge settings for third party LiFePO4
For LiFePO4 and other lithium chemistries, I''m used to a CC/CV (constant current then constant voltage) charge cycle. What I would like is to get the MultiPlus to charge at no more than 50A until it hits 28V (3.5V per cell) (then hold that 28V until the charge current drops to 5A. I don''t want any float stage or any periodic re-absorb.
How to Charge a Lifepo4 Battery Safely? – PowMr
Assuming that you''re charging 12V LiFePO4 batteries, the charging voltage ought to be between 14V - 14.2V. While charging 24V batteries in equal, the charging voltage ought to be 28V - 28.4V.

LiFePO4 : CC / CV / absorption / bulk / float / confused again!
Phase 1: Bulk/Boost is CC up to the absorption voltage. Depending on target voltage, you can get to very high states of charge. Phase 2: Absorption is CV with tapering current to top off the cells. Not necessary on LFP especially if you''re using a lower charge current (less than 0.5C).
Absorption voltage
How much time spent at absorption voltage? 0 Likes 0 · 3 Answers . Alexandra answered · Oct 30, 2021 at 09:45 AM @Matt23. It ... From my experience and training for 16-cell LifePO4 batteries Bulk & Absorption charging rates can be the same since they are the same function with LifePO4 batteries.
What should I set Lithium Battery Absorption Time to?
LiFePO4 Lithium batteries like the sentry have a target voltage. They will absorb high current until that voltage is reached, and then that represents (more or less) the desired state of charge. You can reduce the target voltage slightly (eg from 14.6V to 14.2V ) to increase cycle life, but at reduced usable capacity.
Battery charging
Absorption. In the second stage voltage peaks and stabilizes and current begins to taper off as internal resistance rises. The LED lights at this stage blink green but there is now only a short delay before another green blink. 3. Float. At this point the charge on the batteries is maintained at an optimal level also known as trickle charged.
