Battery Connection

[wolfdogstinkus]

Standard Tamiya connector, TEU-101BK(standard tamiya ESC), ansmann 18T motor

The battery connection is becoming too hot to touch after a few minutes runtime, model is a Mad Bull.

What is the usual cause for this?, bad connection?

I also have a pumpkin with a 19T peak racing motor and this is running fine and cool with the standard Tamiya ESC,

I did try a search as I have seen this subject come up before but I couldn't find any relevant information,

Please help.

Yes, bad connection. I've seen the Tamiya plugs melt completely from it using only silvercan motors.

It's common with Tamiya plugs. I cut them off and solder on ribbed High Volt plugs instead (Deans). Never an issue then. The ribbed ones are much easier to get apart than regular deans.

Thanks Mark,

I was hoping that you would be about!,

What about 1:1 spade connections?

Would they be better than the Tamiya connection?

[TA-Mark]

They would work, but very easy to get the polarity backwards which has dire consequences. Crimped ends still do corrode. I don't use them on my 1:1 cars, prefer to solder wires.

Thanks again Mark

The standard Tamiya connectors are useable when new, but over time the tubes start to spread which gives a bad connection. This causes it to overheat and if you leave it long enough one day you will find it has melted together. Fitting a new Tamiya connector will fix things, but long term the best solution is to replace them with decent connectors like Deans or Powerpoles.

Thanks terry.sc, I noticed the other day that the tubes were not connecting properly and when I connected the plug it had actually pushed the wire out of the plug on the ESC side, time for a new connection me thinks,

Many thanks for your replys.

Changed the connection for another tamiya one that I had and all is well!, Thanks again for helping.
