It's that higher level of understanding that I am seeking by posting here.
The LiFePO4 pack is Headway cells 40152S. They charge up to about 55V. I want to add about 13V using a 15Ah SLA. I have a (nominal) 60V charger.
I know. I know that mixing these into one pack is a bad idea. I do read warnings about it, but I have not found a good explanation. I do want to know the details of what would happen during charge and discharge cycles if I added a 12V SLA to a pack made up of 16 LiFePO4 15Ah cylindrical cells...
This is the controller, but I could install a Crystalyte 408-4012 controller:
This is the motor:
I am currently...
I have a 750-watt trike motor driving the rear axle on an adult tricycle. When I crank the throttle on full, the motor cuts out after about 15 seconds, but it will run steadily if I hold the throttle at a lower power. What adjustments do I need to make in the CA to correct this?
You asked me if I had BMS.
I was using a non-bms pack on the motor (the one that cuts out) which powers my drive train. I switched that pack with a bms pack, the one that drives my front hub motor. I went for a short run this morning and the motor did not cut out. I will test some...
I have the CA set to ramp up gently. It's the reason I bought the CA. The motor was starting up with such ferocity that it was wrecking freewheels. If I set it to bypass mode will it also bypass ramping?
As amberwolf said, "this sends the exact same throttle signal out that it gets in, no...
"Describe your EXACT procedure to restore functionality after the cut-out. Voltage readings?"
Actually, I have not had a chance to try some of the suggestions. Hopefully, depending on the weather, I'll have a report tomorrow -- and maybe a solution.
Sometimes it runs for several minutes...
Thanks for the quick reply. Here's some more information:
The wire colours for the two three-pin connectors are:
red, green, black
& red, black, blue
I'm not sure which is the PAS (pedal assist) or which is the throttle.
The wires from the two throttles I have are:
red, black, white
& red, white, green
I'm installing a new three-wire throttle, having to change connectors and match up wires. I know which wires carry the 5 volts. If I connect the 5V wire from the controller to the 5V wire (red) on the throttle, will it be safe to guess at the ground and signal wires?
