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?

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. |
