SIMPLE Parallel/Series Select Switch
like one of the cooment bellow, i too need to use 3 batteries but 4P2T seems too scary for me but i hope someone can help me out with an alternative for my requirement. using DPDT (on-on-on) switch, how do i wire up to achieve the following positions (P) for batteries connected in parallel: P1 > 1 battery, P2 > 2 batteries, P3 > 3 batteries. so far i only have the image below to refer to and i hope someone here can show me how. thank you~
I am trying to connect Audi A4 power seats to work in my 1964 El Camino. Each seat function motor has 2 terminals and in testing each motor when I put my 12v battery power to them the motor moves one way and when I reverse the pos & neg wires, it moves the opposite way. I cannot use the OE switches as the seats have airbags and I don't want to set them off accidentally so I want to install 6 dpdt switches, 3 for each seat. How do I wire them to the 2 terminals on each motor? I see how to wire the switch, but then what wires go to the motors?
I have a project where I will have (80) 3,2VDC 90 AH Life-YPO4 cells that I would like to set up to be in one of two configurations.The first configuration would be 2 parallel strings of 40 cells each for 128 Volts and 180 Ah (23 kWh) of capacity.The second configuration would be 5 parallel strings of 16 cells each for 51 Volts and (5x90=450) Ah (23 kWH) of capacity.Maximum load will be 16 kW at 120 VDC (130 Amps) for config. #1Maximum load will be 12 kW at 48VDC (250 Amps) for config. #2I would love any thoughts you have on this scenario.
SIMPLE Polarity Reversing switch
Hi Anthony,That's exactly what I do. I switch it to parallel and hook my shumacher charger up. Keep in mind that it will take twice as long but when charging in parallel. However the shumacher is way better than the PW charger and will shut off when full. - Kubert007
No I just hook the charger up when it's time to charge. - Kubert007
Agreed! I am wanting to do the same thing with my sons jeep hurricane. I have one other question though. Would it be possible to do this setup and be able to charge the batteries in parallel with a 12v battery tender hooked up? Kubert007, how do you charge your power wheels battery? Thanks in advance - AnthonyC152
Cool, do you hook up the charger with the clamps onto the terminals or do you have it hardwired? I would like to have it hardwired if possible - AnthonyC152
I'm rally glad you found the faulty connection. Please, feel free to put up some pics of your project, I'd love to see!
Kubert! First, thanks for makin me smile, I am forever amazed that people still look at this 'Ible.Second, I have looked your switch up on Amazon and based on the results I have seen there, the seventh pin should not matter, if you are not trying to get the lights in the switch to work. I do not THINK that you will be able to get them to work, and to be honest, I haven't studied the diagrams, they might actually burn out ... If your pin 2 of that switch (using it's own pin numbering) is connected to the POSITIVE side of one of the two batteries, you can ground pin 7 for the lights to work.Third, if you wired exactly as in my 'Ible with the switch I have found in results on amazon (which happens to show the pin numbers in the same order as I used in my instructions :P ) I do not see why it would not work. So let's see if we can fix this. You say in the 1-4 position, you get 12 volts but in the 3-6 position you get nothing? Did you remember to connect pins 3 and 6 directly to each other? Would it be possible to take a photo of your work for me? I'll do my best to figure it out for you!
Looking for a solution like this for... a 12v solar panel charging THREE x12v leadacids in parallel, then a switch to get the series 36v required for ebike.Or would a DC-DC converter be easier? (12 up to the 36) - that would require some kind of balancing - would 12 to 13V zeners across each battery provide a bypass?OR I guess i could connect in permanent series then charge each battery as needed.
