5T motor current draw
 

Hi all,

as per the title, what kind of current draw will a 5T motor be capable of? I am trying to make some calculations as to what benefit I will get by increasing cable size or installing double deans etc. I have 70C batteries but I cant see 70x5A getting through anything in my car. What have people measured perhaps?

Thank you

Hmm, what kind of car are you running?

Modified tc, 2s.

Ok I have done a bit of digging....

LRP x12 5.5 has a nominal power (in or out I dont know, assume output for now) output of 486W so at 7.4V that means at the very least 65A (I would assume that to be continuous rating). Seesh, I will do some calcs on battery, wire and connectors resistance and see if there is anything to be had. Acutally, I think this would be only of interest to a stock racer where a higher voltage at the motor means more power output for the same current and therefore less heat......

Any imperical readings would be great if someone has done some dyno work.....

You're uh... doing a lot of unnecessary calculations.

Use TQ 13ga wire for the motor and 12ga to the battery. The wires you use isn't going to miraculously increase the power delivery of a motor, at least nothing that's even noticeable. You're better off just using the time to throw down more laps rather than nitpicking with voltages and watts.

Also, I think the word is empirical.
