Hello, Do you know the power rating of the DC motors? That will be needed to determine the size and type of batteries and what kind of power system will be needed, especially if you need to charge the batteries. Are you also looking for a tutorial on how and why the design is done in a particular manner? And, do you realize that for simple switch control you do not need any relays if the motors are small enough? Let me know if I an help. Best regards, Stuart Borden.

If you don't need a control voltage on battery, it will be use only DPDT switches but 5*2 or 7 numbers. Contact me if you want discuss details.

Electrical & Electronics-Control Circuits & Panels Designing and Manufacturing: MCC, PLC, PFC Panels. PLC/HMI Related work. Temperature sensor, Pressure sensor, Level sensor, Flame detector, Gas Leak detector, Tanker Earth Fault sensor etc related control circuit design with alarm for MS/LPG/CNG storage and transfer system .Utilization of Flow rate and Total Flow Meters. Manufacturing of needed Panels. Solar Panels with needed accessories up to 5 KW based on customers load. 15-20 years of experience. Please give us the details of DC motors to be run and time duration of each motor operation before recharging of battery so that AH capacity of the battery and its charger specification can be suggested . Battery voltage can not be 12 -18 V DC. It depends on the spec of the motor to be run. Please check and stick to that. It may be 12 V DC. Thanking you, RJT ELECTROTECH

Hello, I have ready and tested circuit for this job. It control only one DPDT relay to change a direction with push button. I sell it on ebay. I can make for you custom circuit for 5 relays to fit your expectations and PCB layout if you need. Also can make working device.

I've just made similar circuit a few days ago which could control 3 motors. So i can easily make that same circuit to control 5. The circuit can be made in two ways - 1)using only switches(any kind) 2) using transistors and switches( requires less switches) You can get the design done without any cost.I don't need money just working for science. Good rating will be enough for me.
