Simple query

Although most standard li-po's are designed for 3.7 volts d.C ....it has been said these can be charged up to 4 .2 volts,,,as opposed to their assigned designation of 3.7
I would like some clarification....if possible

3.7 is the nominal voltage for a cell and the 4.2 is the fully charged voltage for the same cell.

For the gruesome details do a search on "LIPO nominal voltage".

All rechargeable batteries are similar in that respect.

Thanks

For that info..
After reading so many pieces on the possibilities of things going wrong while charging these,,I did need some clarification.

Are there any signs that I should be aware of if the batteries are under some sort of duress .Would they feel warm to the touch,,,,,,?

Batteries have been used for centuries,,,,,but clearly LI PO'S,are a different animal indeed

Batteries being a little warm to the touch after flying is normal. It's when the battery is too hot to touch or it's puffed up that you need to worry. If you follow the basic guidelines for how to use lipos then you won't likely have any problems with them.
