Is it optimal that STBC08 Charger charges to 4.2v (100%) ?

[Aharon1]

Hey

We are using the STBC08 to charger a LiPo battery,

the device charges to 4.2v which is the maximum voltage for battery,

However I understand that charging to 100% is not optimal in terms of battery lifetime, and most sources recommend not charging above 90%,

Was that being taken under considerations when designing this product?

I am considering limiting the charging myself but on the other hand don't wish to interfere with the function of an already tested charging device

I would appreciate any insights on this issue.

Thanks!
