July 5, 20241 yr It's best not to leave the battery on charge with the green light if you don't have a reason to. Either way, it's nothing to panic about. That's certainly prudent. Proper storage and use affect safety but charging not so much (unless the BMS is cr*p). There's a pressing need to understand charging well because inept and harmful legislation is entering the pipeline based on the media's ignorance about it.
July 6, 20241 yr Remember though that balancing is very slow approx. 100ma rate and voltages quite close.
July 6, 20241 yr Author I guess I’ve been a drone in lots of people’s ears regarding this thread! I’ve always been rather pedantic in how I go about things. Now I understand a lot more I shall make note of the achieved voltage (rested briefly) when I charge, to then decide if I let it sit on the charger a little longer if it’s sitting in (say) the 41v ish range, in the hope of improving the pack balance.
July 6, 20241 yr I just unplugged my charger. I put the battery on charge at about 17:00 yesterday and forgot about it. That's what I always do. One time, it was left on for a week!

Ah, But now I know that with a good quality BMS I have nothing much to fear if I do the same! I do use a 240v countdown timer though. At c. £15 from eBay, I can set charging times of 15, 30, 45 minutes, or 1h, 2h, 3h, etc. and forget about it too!

I've got some Tapo smart plugs (thanks to Ovo). These can act as a countdown timer, but also give interesting information about the charge rate. (Only about input to the charger, but still very informative.) To take full advantage would need a little more work. Shame they don't have a PC client; they have APIs I might look at again.
