@Karthik Keyan, Welcome to EasyEDA. Any net on the PCB with same the net name as that assigned to a copper area will be covered by that copper area. I suspect on your PCB you may want to put a BAT+ copper area on one side and a GND copper area on the other?

Hi Yeah I have put the net BAT+ and GND as the copper area. Actually I don't know the use of copper pour. I thought with out doing copper pour, the PCB design is not complete. Is it necessary to do the copper pour? I'm new to PCB design. Thanks.

@karthikkeyan221, There are situations where copper areas are essential and there are some situations where they are a good idea but not essential. Your PCB is an example of where copper areas are a good idea but not essential. If laid out properly so that traces don't cut them into too many small or isolated sections then BAT+ and GND copper areas will significantly reduce the resistance of the BAT+ and GND connections. It will also increase the current carrying capacity of the respective nets. You could achive much the same effect simply by using wider traces but using copper areas may be simpler to achieve. Without some specification describing what your design is for and what it's design aims and performance objectives are, however, it is not possible to say whether the use of copper places will be necessary or helpful in your PCB.

If the copper is the net as the track, the track will be covered. it is normally.

@andyfierman The circuit is to charge the batteries from the socket power through DC power jack and also to power the Microcontroller. Here I have 2 Battery packs and DC power jack to power the microcontroller and others sensors. When there is no power from the socket, the battery packs provides the power to the sensors and Microcontroller and if the wall adapter is connected, it charges the batteries and power the microcontroller. In other words, it is a UPS.

@andyfierman I'm trying to charge 18650 batteries of 10 numbers using AC to DC converter of 5V,12A with 2 power outlets.

@karthikkeyan221, You're not giving enough information. You need to answer some fundamental questions. Pleae provide a link to a datasheet for: * the "18650" batteries * the "AC to DC converter of 5V,12A with 2 power outlets" "I'm trying to charge 18650 batteries of 10 numbers" * Are all 10 of them being charged at the same time? * Are you trying to charge all 10 batteries at the same time? * Are you trying to charge 2 sets of 5 at the same time? * In series? * In parallel?

Trying to see how your circuit works from a PCB layout to advise on the safety of your design is open to errors and a waste of time for people who are trying to help you. From your PCB layout it looks like you are using separate LiPo chargers for each battery **but you have connected all the batteries in parallel.** ### Therefore as it stands, your design is incorrect and dangerously unsafe. Until you create and make public a fully documented schematic for your design (with complete BoM information and links to device datsheets) it is irresponsible for: 1. you to proceed with it; 2. anyone else to try to advise you how to proceed based on the information you have provided so far.

@andyfierman For your questions:  I'm trying to charge all 10 of them at the same time in series and the batteries are connected in parallel to have same voltage with increased capacity. Could you please tell me what is wrong with the circuit design?

Please refer to my previous post.
