Help choosing battery board
Account cancelled 2019-02-06 11:16:03 1849 Views1 Replies So I want to charge a 500mah 3.7v lithium battery(battery A) through a microusb and I want that battery to power another lithium battery(battery B) 200mah 3.7v. I need voltage going to battery B to be greater than its current voltage so it can fully charge, so maybe 5v output from A to B. Also I want to add a power switch to turn off battery A. This is for a portable device. Which module is best for this purpose? Please and thank you whoever helps.

For the battery charger, you can consider to use this one: https://www.dfrobot.com/product-851.html and if you want to boost the voltage, this is the power booster to 5V https://www.dfrobot.com/product-1766.html robert.chen
