I would like to ask a question regarding about designing a flexible battery holder for a circuit board.
This flexible battery holder can take in most phone and/or camera battery. The circuit board have a LCD that display the battery voltage and have some variable resistor that control the output.
The output is a USB port and can be used to charge any electronic devices.
May I ask if I can post such a question on designing the flexible battery holder in electronics.stackexchange.com? If the question does not belong to here, please enlighten me which stackexchange.com site should I post this question to.
