What might happen to integral epropulsion ouboard battery if stored in unheated garage over winter - any experiences - surprised instructions says 15 degrees min but not keen to bring inside in case it was to catch fire
Electric outboard - cold weather storage

I stored mine in my unheated (brick built) garage last year with no problem and it is in there now. Possibly warmer than my boat that will be ashore in the next few weeks.
Don't forget that is should be around 60 to 80% charge, and if not used for more than 3 months or so the battery needs to be bought back to life by charging for around 20 minutes. The "not working" caught me out after the first winter !

Reduce to about 50 - 70% charge and it'll be fine ... give it a periodic check to make sure its not discharged ...
I know people who put all forms of Li batts in fridges ...
The main thing to remember - DO NOT TRY TO CHARGE IT before its returned to reasonable temp ...

You won't have a problem storing it in a garage. As Refueler has mentioned, Ideally store a Lifepo4 lithium battery somewhere around 60% charge. They are fine at stored low temps so long as you don't charge them below freezing.

15 degrees C? 59 degrees F?
I would think, as others have stated, no charging below 0-4 C and useable below freezing. No storage or use below 59F is pretty useless IMO. Heck, that's more than half the year and much of the sailing season, if we include nighttime lows.

Regarding the state of charge for storage.... I have feeling that epropulsion batteries automatically self discharge themselves to 75% if left unused for a time.
