Accessory Switch/SOC Switch
Question: I want to wire my 48v to 12v converter and my SOC digital meter to an actual switch, independently. Given i will be placing the switch on the wires on the 48v side, will i need a 48v switch specifically? I know most switches that are carried at the local store at mainly 12v, so i assume i will need to special order 48v capable ones, right?

Re: Accessory Switch/SOC Switch
To be safe look for a 20a switch. Most switches will be 15a.

Re: Accessory Switch/SOC Switch
Much thanks to the both of you, i just ordered 20a switches. Given they are both lighted rocker switches, would it be okay to wire the ground for each switch to the same negative wire? I have one negative ran to the dash already for the SOC meter but only a positive wire ran to control the converter.
To clarify, I will have my 48v to 12v converter on one switch and my accessories on another separate switch. However, i wanted to share the same ground between both switches. Would that be okay? I don't want to cause any interference with the SOC meter. Thanks |

You will need a resistor on the negative side so the light only gets 12v instead of 48v. The best method is to use a 3.9kΩ x 1watt 5% resistor on the negative wire. The other method if you have 12v batteries is to run the negative wire to the negative post of the pack positive battery. In this case for safety, the wire should not be black and you should add a diode with the cathode pointing towards the battery post to make sure it can only sink and not source current. The diode should be installed close to the battery. |

Re: Accessory Switch/SOC Switch
SOC meter, would it be best to wire directly to battery terminals or off the solenoid to only be on while running? If solenoid is best bet can you help me be certain i wire it correctly by explaining what exactly i am wiring it to on the solenoid? I don't want to screw anything up by wiring incorrectly. Thanks!

Re: Accessory Switch/SOC Switch
Also, my meter is showing 44.8v or so when fully charged and still connected to the charger. Obviously something isn't right given the chart I've obtained off this site leads me to believe that would be much less than 10% SOC remaining. I simply wired the meter directly to the battery terminals. Positive on the battery on the passenger side of the cart and negative to battery closest to the rear of the cart(right in front of bagwell). The cart runs great and have yet to see the thing slow down or die while riding after 2.5 hours of off and on total driving in one day.
Any thoughts? |
