What am i doing wrong....Turbo 30 problem?? Or am i dumb...

[jamesbernatchez]

I have a Turbo 30 charger and 15 amp power supply(see other thread) it works fine and gets power...but when i go to charge my battery it shows its charging for 3 seconds and then says hook up battery. is my battery hooked up to the right place???? I have no idea. I soddered my pack together myself and its my first pack. From what i see i soddered it right, i have no idea why its doing this. Its my first competition charger and im begining to hate it. I took pics of how everything is hooked up so you can see if im doing something wrong. Please help...i cant even run my car to see if it runs because my batt wont charge :confused:

I hooked up a battery that is a stick pack that i bought and know it works and does the same thing.

I thought it was the power supply and so i tried my car battery and the same thing happens.

Please help...i would like to run it today :)

Judging by the connection you soldered , one of the bridges goes - to -/ should be + to -. think thats wrong.

Good luck!!

Yeah, it seems to be soldered negative to negative as terrible said. The black wire connecting the 2x 3 cells together.

btw, nice solders, pretty good!

[jamesbernatchez]

Thanks for the compliments. It was my first time soldering batteries:)

And no...i tripple checked to make sure the batteries were soldered right! :D

I figured out what was wrong...One of the 15 amp fuses was blown....and the left leads are to the power supply. The thick leads on the right are to the battery and the thin ones are watching the voltage!

Jeeze, first time soldering batteries. That's impressive..I just wish I could solder batteries without them falling apart every crash....

You should also use the current sense wires to increase the chargers accuracy. It's more for discharging but its a good idea getting used to hooking them up.

The sensor wires are there to detect the deltaV (drop in charge voltage to indicate peak charge). They do nothing on discharge cycle.

Soldering job looks OK but it's difficult to tell if they're cold solders by the large amount of the solder blobs. The secret to a good solder on batteries is to clean the battery well, flux it to remove oxidation, use a good iron that transfers heat quickly (no not a gun) of at least 40W, tin the battery terminals and bars/wires then place bar/wire on terminal apply heat for 3 to 5 seconds, remove the heat and allow to cool while still holding the bar/wire in place. Voila! a perfect solder.

Yeah...there not bad...pretty good for my first time. Its not the first time i have used a soldering iron, just the first time doing batteries. I redid that bad connection on one of the packs and its much better now. I know what a good connection looks like(ive read up on it alot and checked out alot of peoples work to see whats good and bad) and i think mine are good, but they always could geet better.

Looks like you are using the wrong power leads, the ones on left side goes to power source the ones on right side along with sensor wire are attached to battery. That's maybe why fuse was blown.

I own the 35GFX to be sure of correct operation download the manual from Competition Electronics, look under discontinued products or try the CompetitionX website (www.competitionx.com) they have a nice area for lots of manuals. The Associated links haven't worked for awhile though.

Thanks, I figured that out 2 days ago and everything has been working fine ever since :)

The small leads from the TURBO35 are voltage sensing leads. They are used mainly for the discharge or cycle modes to get an accurate voltage measurement.
With the increased resolution of the TURBO35, it is important that you remember to connect these leads; this will ensure that you get all the
accuracy which the TURBO35 can deliver. Connect them directly to the battery pack while observing correct polarity. Voltage sensing is also done thru the
heavy current carrying leads but will give slight voltage errors especially with heavy charge or discharge current. The slight error, however, doesn’t effect the
charging of the battery.


That's right from the manual

Thanks for the clarification. I didn't realize (or remember) that they were live during discharge.
