Need help, nebie here

I have purchase a KingTech Power EPS with a T-motor T1804 ,ESC Tahmazo Pro-CS-13 13V
Soldered the points together already , plug into the battery 2cell 240MAH (35C)
turn on transmitter, then tried to push the trottle but the motor not turning , is it the soldering problem or...
After a while the battery bloated up some chemical leak i guess the battery is spoiled ,any recommend which battery should i get and what's the problem connected

From your picture, you need to insulate your motor bullet connectors. The risk of a short is just too great. Also, did you solder the battery connector correctly? Sounds like you shorted out the battery at the battery connector end.

You may want to read up a little more on soldering technique

#1 Please do use proper bullet connectors, also properly insulated.

The battery bloat could be a million other reasons...

Can you take a video of the entire setup and the problem occuring?

From the picture I can see only a soldered ESC connectors. That's all we can comment about cos we cant see other things?

Hi,

Your soldering technique is not quite correct. For these bullet connectors, the wire strands should go into the barrel, so that the end result is "in-line", i.e. one straight line from wire to the connector.

As for the soldering process itself, this video explains well. You don't need a holder like that, but something is needed to steady the whole arrangement while you solder.

Battery bloating could be due to short-circuit (did you see sparks?) on the battery connection side. If you provide overall photo, perhaps it will be clearer.

As others have mentioned here, make sure you insulate bare connections with heat shrink, else...

your esc may be short too

You could have also short your esc too.

Thanks for the help , can i still redo it ? is the centre soldering correct ?

[STJzzz]

the ESC connector hole is too small for to go into

[xuen7]

you referring to the esc connectors.. Then for that you gotta just use a different size connectors.. They come in various sizes from 2mm to about 8mm in diameter depending on the current draw requirements...

[STJzzz]

The connector holes come with the motor

Actually I was just looking at some of the ESC and motor that I have, and turns out that 18 AWG wires can fit 2mm bullet connectors - so I'm not sure why you face the difficulty. Maybe your soldering attempts have clogged up the connectors or somehow made the wire conductor diameter larger due to leftover solder.

Two options you have now:

Either cut off the "dirty" wire conductors and strip it again, start fresh and clean. Make sure the wire strands are twisted nicely, not frayed, and test-fit into nice, new, clean 2mm connectors. Actually you can re-use your 2mm connectors if your soldering skills are fine. Just re-melt the solder that's there.

Or, you can use the next larger size of bullet connectors, 3.5mm. Solder these on both the ESC side and motor side.

In both cases, get heatshrink of the appropriate size to insulate your connections. Fit the bullet connectors together first, after soldering, to get an idea of how much to insulate.

Plenty of videos on the web to guide you through the process.

At this point, I strongly recommend that you get someone to help you with the soldering. Also, you need to determine if you have flied the ESC.

Let me know if you need help.

Thanks for the help , i think that i will ask someone to help

Bro ST,
likelyhood is that you have shorted your esc (with the connectors exposed) and also your batts - that probably explains the batt bloating and leaking..

And for your info, damaged / punctured Lipos are dangerous.. (Fire Hazard).

Prepare a container and mix ionized salt and water. soak the damaged batts in it till it stops bubbling then throw away. DO NOT ATTEMPT to charge the batts again.

Find a friend with exp or go to LHS for help and assistance.
