The Altrax Controller has some nice functions that help with Lithium batteries.

Also make sure You set Your "Under Voltage" and "Over Voltage" settings to match your battery.

The "Under Voltage" setting should be a little higher than the lowest voltage you want for the pack.

The "Over Voltage" setting should be a little lower than the highest voltage you want for the pack.

The controller will then automatically reduce the discharge current or Regen current to keep the battery from getting outside the specified settings.

It is particularly useful when the pack gets a little low as it creates an automatically "limp mode" instead of having the battery shutdown if you press the accelerator hard.

Probably a dumb question...but what is the desired highest and lowest voltage? Ex: I have a 48 v cart with 80ah Allied Lithium batteries. (4 x 12v).

You need to find out from Allied what is the minimum and the maximum voltage their batteries can handle.

Just multiple that number by 4 (4x12v batteries) to come up with those numbers.

For my 14 cell Leaf pack, I use 3.2v for minimum and 4.19v for maximum so I have mine set to:
Under Voltage=45v
Over Voltage=58.5v

The controller will automatically reduce the current during Regen to keep my pack under the "Over Voltage" and reduce the discharge voltage to prevent the pack from getting below the "Under Voltage".


If someone gets those numbers from Allied please post an update so other members can use for reference.

Heard back from Allied...they've been great with all my questions.



the absolute Max is 14.6V
Absolute min is 10.4V

For those 4 x 12v Allied batteries (LiFePO4) use:
Under Voltage=44v

Over Voltage=58.0v

As far as limiting the current, the Armature current has no direct impact on the battery current.

The battery current should be limited based on the battery discharge rate/time limitations.

The Armature should be limited based on the motor capability.

You can set your battery max current to 165A and the Armature max current to 400amps.

Your motor will still get the 400 amps it needs for a good torque during take off while not using more than 165 amps form the battery.

The reason for that is that at low speed the motor is not getting the full battery power, the PWM effect regulates the power so input = 165A x 50v while output = 350A x 24v.
Can this be done with the Navitas 440a DC controller with the OTF package? I'm trying to determine if I want that with my Allied 80ah setup. Would it be worth it?
