3 Stage Charging ? If you really want a "Float" I guess but it's unusual.
2 Stage works tickety boo for LFP as all you need is CC/CV and set your end amps (pending on gear) to 0 or 1 Amp.
3 work arounds for the loctite:
1) You can use a Serrated Washer (not the split lock washers), they hold better IMO.
2) A Missus trick learned years ago for when Loctite is a problem. Once the nut is tightened on and all is set & tested as good, use "one drop" of nail polish right where the tread goes to the nut. Coloured makes it easier to clean off later so you can see residue to wipe with pure acetone.
3) Double Nuts, if you have enough thread above the nut.
3 stage because I need float because I'm in an always-on RV system with DC loads. And I can't just charge to 3.4vpc average of course (no balancing). Orion doesn't have tail current capabilities that I'm aware of.
The loctite wasn't for the nuts, it's for the studs inside the cell terminals. And it was to prevent me from pushing the stud into the cell terminal.
