I have a Li-Ion 3000mAH battery like below
Connected them as below
What is the maximum current that I can get out of Output + , Output - pins. If I use the battery directly to my load I guess I can get up to 3Amps as battery has 1C capacity. Will it be the same from Output +- pins. In other words , are these pins just an extension of my battery (or) do they limit the current to 1 A ?
Can I charge the battery ( as depicted above) and also connect to the load to it at the same time.
My requirement: I am trying to power on my SIM800a module that needs 3.7 - 4.2 V and 2 A current max at some times. So I want the module to be powered using this battery , but just like we use phone, want to use it when the battery is being charged as well. I would also connect nodeMCU( D4,D3) to the SIM 800 ( Rx, Tx) to send and receive data for further implementation. At the moment I am powering my nodeMCU with another 3.3V/5V power supply, but I would want to use the same battery to it too.
Question 3: To power both of them ( sim 800a, nodeMCU) using the same battery , how should I connect them to Output pins.?
