I don't know anything about BMS's but Lithium Iron Phosphate cells can
experience capacity fade even if they have good voltage. I had some cells that
sat around for a year and a half and showed good voltage but when I cycles them
they only had 45Ah out of 100Ah they started with. I thought I ruined them but
I got back 100% of the capacity after the 5th cycle so just note you may need
to cycle more than once.

I guess this may qualify as an old-school question now.
About 12 years ago I built an electric motorcycle. I actually had it up and
running, but other things got in the way and I am abandoning the project. The
rolling chassis will get back it's ICE and I need to find a home for the 7" Jim
Husted motor and the controls. I have a new endeavor now - a small cruising
sailboat (CLC Pocketship). I'm thinking of using a trolling motor as the backup
to the sails and I hope to repurpose some of my 100 A-H Thundersky batteries
for power. My batteries have been sitting for 10 years but still are at around
3.25V. I need to cycle them to see if they are still viable of course. If they
are, what BMS is recommended for them now? I did a bit of searching but didn't
see much.
