great thank you for your help! :slight_smile:
thank you for having reassured me for the unprotected battery
on the other hand for your link of the battery sofirn, they are good, but the problem is that they do not indicate the amps …

and in my table that i posted link, it looks like the LG HG2 is better because 3000 mah has 20A ,what do you think?
and always in my table the LG MJ1 is only 10 amperes and written in red there is written: “best used at under 7A / 21W”
that would mean that the LG HG2 is better but we do not know anything about the degrees not to be exceeded neither for Watts as they write in the table…
