Charging and Using a Li-ion battery simultaneously

My system requires a power which is supplied by a Li-ion battery. However, I need to keep this battery charging at all time so it won''t die. Is it possible to connect the battery to

lithium ion

Accordingly to what I''ve found in several sources (user''s manual of electronic devices, various forums, e.t.c.) I shouldn''t charge my Li-Ion batteries in cold temperatures

Understanding LiPo charging / protection circuit

The charging cycle for lithium ion batteries can be quite complex, especially in the case of multiple cells in series, but typically involves 4 basic steps: Read voltage, if lower than

charging

It will just make much more sense to buy a Type-C PD charger if your devices support it, rather than still dealing with the problem of which USB adapters you can use to

Difference between controlled current and constant voltage charging

Modern charging of lithium and nickel based batteries starts with a constant current, until a certain voltage and then a constant voltage until the current falls to some level

voltage

Cell phone battery charging is handled through a battery charging IC. Typically a switching regulator that varies voltage and current in order to charge the battery. It also

Wouldn''t charging a lithium battery to 80% only defeat the

As you can see, charging to 80% instead of 100% multiplies by 4 the amount of energy the battery will have transferred to you over its life - the only tradeoff being to

Is it possible to have a device with metal case and wireless

Is wireless charging indeed impossible for a device in a metal case like for example a mobile phone? Would it be possible to perhaps leave a small window permanently
