Melting battery!!!

[berna1974]

Hi everibody, I'm new here and I find this site on of the most interesting for who likes electric buggys like I do!!!

I have a Dark Impact wich I played a lot with, and waiting for a brand new Lazex ZX-5 SP coming from UK!
I purchased a Mamba Max 6900 and just installed into my DF-03: after a few minutes driving I smelled some plastic burning...and I found that the battery was so hot that a part of the plastic chassis was a little bit melting next to the bottom battery connector!!!

I agree that the battery location on the DF-03 is really closed and no air flows to it, but still...do you think it is normal???
Do you have any hints to solve this?

I don't really care of the DF-03...but I don't want to melt my new ZX-5 SP when it will be ready!!!!!!!

Thanks to all

by the sounds of it you have tried to use a high powered brushless system with a cheap battery and the connectors or wire cant or te cells themselves cant take the current your trying to draw.

Connectors and wires seems to be fine...I'm afraid that the cells are a bit poor!!!
Any suggestion on cells to use?

www.stormforce racnig have some 4500 coming into stock soon they would be brilliant battery to have.

if there is a lot of ampage running through a wire with high resistance, you have just created an electric heater.

The standard Tamiya plugs are garbage if running anything more than a 540, which you are. So what is likely to have happened is the resistance in them started to melt them.

Don't worry about the cells, make sure the connectors are something good, such as Deans, and the cells will work fine. The next thing may be runtime is low, and new high capacity cells (avoid the IB4200 fireworks) will help that a lot and also give plenty of added *umph*.

Yeah, totally agree but he said his connectors seemed fine, which is a bit puzzling.

what battery type were you using, and was it the cell or the solder connection getting too hot?
