LFP battery absorption and float - report
Bought this 120AH LiFePO4 a while ago https://www.lynaclithium.com/wp-content/uploads/2022/03/12.8V-100Ah-True-Series-Quick-Sheet-USA.pdf. 120AH marketed as 100AH. Don't see this now but on the old...

2oldman says, “My LFP acts strangely when finished with Bulk. On generator charging the gen will surge up to bulk for about 30 seconds, then 'rest' on float for another 30 seconds. It will do that forever….”
I’m not totally sure what the issue might be (because I my solar 660w does entirely all the work…), but shortly after having reached 100% SOC (per Victron BMV 12), starts the cell-balancing regime (say, after a minute or two at rest) observed via the on & off again alternating of current vs volts (a temporary generator loading - I donno?)…This sometimes takes about 20 or so minutes till completed…Aside from this ‘occasional only’ meter re-sync and cell rebalancing regime, I purposely avoid a routine full charge to 100% SOC, instead opting for say 85-low 90’ish %…. I find that a full 100% SOC is otherwise unnecessary - JMO
