Restricting charge to LiFePo batteries.

[Refueler]

Have you seen significantly degraded LiFePo4 systems? Everyone I know of, and everything I've read suggests almost nobody has seen real world capacity loss, and those that have were down to hardware failure.
We do "capacity testing" all the time as we live on board and when away anchoring often get down very low. Everything is recorded to the VRM cloud in real time over Starlink so I can see the history going back years.

Degradation just isn't a sensible thing to be concerned about. I do think setting the charge system up properly is important, and your advice is good. I was simply pointing out that degradation has not been something lithium users have complained about or seemingly experienced. With battery prices dropping faster and faster it's just not an issue.

Come into the model world - albeit smaller capacity cells - but degradation is seen ...

Never said they were not ??

Was just adding to the discussion ..

With something that is totally unsuitable for the OPs purpose and is unlikely to work at all well with LFP anyway.

That is wrong anyway ... the units don't care what batterys ... but anyway - I was only adding to the thread ...

Curious as to what your insurance company policy is on boats left unattended whilst still charging lithium batteries. I disconnect mine ( mains and solar) when away for more than a day trying to keep it around 80% SOC .
