Traxxas flat pack

[truggy83]

I noticed my Jato was acting strange today. The wheels would lag when you would turn them, the throttle would open and close when the trigger is pulled all the way back. The batteries in the receiver and transmitter were fully charged. I tried switching the transmitter batteries to see if that helped. It still acted the same. I than took the flat pack out from the central battery location. I noticed the red wire had some bare wire and it appeared that the wires got pinched when I put the battery in. I swapped out a ofna battery hump pack that was in my pede and the problems went away. I tried to cut the bad section of the wire out and respliced it with electrical tape. It was still acting the same way. Are these batteries so sensitive that I cannot repair the damaged wire? I dont want to have to get a new pack as this one only had like 3 charges on it. Its the 5 cell flat pack that traxxas offers

Well, if it was shorted out, it may not have taken a charge at all and may be dead. Did you try charging it after sorting out the wiring issue? Also, if it shorted, it would have melted the insulation on the wires. You may want to peal off the plastic of the pack and desolder the old lead and solder on a new lead.

Well I have the duratrax peak detecting ac/dc charger. The status light is never to flash while charging although it did when I was charging this battery last time. According to the owners manual if it flashes when charging that indicates a bad connection. I unplugged the batter and plugged it back in and the status light stopped blinking. It charged like normal and the charger went into trickle charge when the battery reached its peak.

This was all done before I discovered the problem yesterday. I haven't tried to charge it again since trying to repair the pinched wire. Maybe I will give it a go. Before when I tried to fix it and test it out, you could hold full brake or full throttle and the throttle servo would open, close, open, close repeatedly by itself.

well I pretty much torn the entire pack apart, stripped all the wire casing off and looked at the connections. No matter what I did the battery still acts funny in the car. Apparently I have just created a $30 paper weight. I will be back at the hobby store today to buy a new one. Be careful when you install you battery packs so this doesn't happen to use. Tolerances in the jato mid battery compartment are rather tight. Be careful not to pinch any wires.

You probaly have a bad cell or cells toss it by a new one.
