How to add a charging circuit after replacing with chargeable battery?

Kevin Chen18

Hello, there

I am trying to modify the CC2541 keyfob schematics, so that chargeable Li battery could be used, instead of coin battery.

For this purpose, the DC-DC converter TPS62730 has to be replaced and charging circuit needs to be added.

Could someone give me some recommendation for the above changes?

Your helps are appreciated.

Kevin
