Default HELP Please

Im running a Durango 410
speed passion LPF speedo
speed passion 6.5 V3
87 spur
23 pinion
zero timming
forward only
DRRS start mode 9
brake mode 1
Ive always had a problem with the battery wires getting warm more the negative terminal side.
Today while doing a practise session i melted 2 sets of batterys,1 set of orion 5500 90c and 1 set of nano-tech 5100 65c.
the orions almost doubled in size just saving from exploding and the nano-tech melted the negative terminal out of the battery.
all wires have been checked and nothing has shorted out,all wires have been heat shrinked at the soldered ends so nothing is exposed and cant short out anywhere.
Anyone got any ideas before i bin the electrics and start fresh

Cheers

Should add, he was getting similar motor and ESC temps to me in my 44.2 but my batteries were barely warm, also Turnigy Nano-Tech 5100's the same as one of the ones he had problems with.

Motor was running about 130, ESC 100 degrees.

A thought, if you cake the motor out does the driveline feel free when you turn the spur gear by hand? Do you know if there's really thick oil in the diffs?

Were you using the capacitor? I used too have the. Sp lpf in my 410 and space is. Very tight

Not sure using it or not would make a difference though

Also just a thought my 410 used a 7.5 v3 motor with my lpf and my batteries were always warm after a race. Maybe the 6.5 is pushing the esc too far causing it took really suck the batteries for all they are worth

Think the lpf is rated to 5.5t. But id take that as a bit of a over estimate as most with most esc it also depends on car type. Sometimes the esc say 5.5t for example but only onroad. And they say a higher turn for offroad use due too the extra strains placed on the motor/esc.
