i am working on ups for the router i have some questions
1. i am using lithium battery 3s whose output when full charged is 12.6 so i need 13v to charge it i have adopter 12.22v i need to boost the voltage is there any way which transfer is best that work without producing too much heat i don't want to use xl6009 or any module ... just simple circuit.
2. 12v*1.5a= 18watt == 9v*2a = 18watt. what if i give 9v 2amp to a 12v load is it work?
