Problem with 6 cell upgrade, plz help

[r3ap3r03]

hi, yea i just did the 6 cell upgrade, following the atomic mods tutorial i didnt have wire that was the same thickness so i got some 18g speaker wire i found in my room. got it all wired up, when i put the main 4 batts in it is fine but when i add the 5th and 6th the negative on the new 2 cells the spring u use to push the batteries in get red hot and and the spring compresses so i have to stretch it back out... no wires are crossing and none or touching any metal screws

any ideas what could be the problem

thanks

Sounds like you have the polarity of the add on 2 cell pack backwards. Double check your wiring against the tutorial and I think you'll find your mistake. The only other thing I can think of is that you have the new pack in parallel with the board instead of in series.

thanks guys i got it now, i didnt take off the ground wire that goes to both batt packs.... der....

but on a better note my gen1 with bearing n stage 2 red motor does at least 25+mph now , maybe i can get closer to 30mph with blue stage 2 in there

25+ with a 6 cell? that sounds kinda wrong.. maybe like 20+ but 25+ is a bit too much, unless u have an external turbo or something like that.
