making female deans plug jumper

[danielc79]

Hi
I just recently switched all of my batteries over to deans plugs, so i don't have to use a converter for trx connectors to deans for my savage flux. When i did so, i made a jumper (i think is what its called) i soldered the two ends together on a female plug and put it on my esc, so that only one plug is used. i did this so that i can easily switch from 4s to 6s with different parrallel adapters.

Well, i noticed my truck started cogging. while holding down the trottle the truck acts like it loses power and gets it right back (within a second or so) but i don't know why. Could this be because of soldering that one deans plug closed? perhaps it causes some minor resistance? I didn't think it would cause this, but not sure what else i should check.

Also to be noted it seems it gets worse when the voltage drops some. i checked the batteries and they were still at about 3.9v per cell, but at 4.2v per cell i didn't notice this happening.

thanks
