Hi all,
I've just got some 3.7v single cell lipo battery's, the data sheet is a bit chinenglish?
They have a r5402n101kd-tr-f in the pack which protects from over current ,over charge.
It says supply for that ic is up to 12v , max charging voltage for the battery is 4.20 v +/-0.05v
I'm still not sure how to charge them, can I use a 5v wall wart type thing which is easy to get hold of and leave the on board ic to sort it all out, or do I need to include a lipo charging ic in my circuit to make sure the battery charges safely. Most of the ones I have seen need around 6.5v supply though, not as common as a 5v phone charger/USB etc.
Thanks Geoff
