I donât think 24 hours beforehand counts 
- thatâs if youâre storing them for looooong periods of time (I used to work in a warehouse for a company that made them).
But youâre 100 per-cent correct, of course - storing them for any REAL length of time at 100 per-cent charge isnât the best practice. I store mine at 40 per-cent charge in a fire-proof box, along with a shoot load of lipos from my other ventures. And you donât want to store them without any charge, either.
Yeah, I know that site well - some great stuff on there.
P.S. Sorry about the multiple edits - I canât seem to type properly today.
