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
