Current capacity of batteries wired in parallel


I'm wondering what would happen to the mAh when I connect 2 5000mAh batteries in parallel. Would the mAh over all be 10000mAh?!

Answer



Yes. Connecting voltage sources in parallel increases AH and connecting in series increases voltage. These increase of voltage and current are additive.


You should not connect different types of batteries or cells. Same type batteries or cells should not be connected in parallel if they possess different voltage.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
