I am assuming all EUCs have smart BMS as part of their battery that would prevent overcharging. Is it possible to configure this setting and set certain limits to make your battery last longer?
Yes. All batteries have BTS which is Battery Management System. These are large batteries with many cells and something has to do the management. Don't worry about that. In terms of being able to set a limt of something like 80% - that does not exist in all models. As an example, King Song S22 has this setting.
