Hi There,
I have the batteries(Pack of 2, 21700 battery pack with approx. 7000mAh) with inbuilt charging circuit. The source for the battery charging is through 5V Solar panel.
Default power source for the circuit is 5V Solar panel. If the solar power source is not available it has to switch to battery source.
Is there any circuit/chip which can acts as switcher between solar panel source and battery source.
NOTE : My batteries are packed with charging circuit on it.
Leads will be appreciated!
