What A Plonker !!!

So we all have these new Lipo Cells with no fly leads and the Corally type of plugs that push into them . . .

Well I love the Deans plugs as you cant get them the wrong way round . . . . .

Yea you know whats coming next dont you . . . .

Yep I was still trying to find out WHY im missing laps and the Steering servo is twitching 2mm either side of center . .
Well in the case of 1s Lipo drivers out there with a TQ boost its a sign its on the way out so get ready to get a new one I did put a volt meter on it last week and it showed 6V

Any way racing the Dave at Mercc and all of a sudden my car starts to go back and forth ( stick is in forward position )
WTF ( What The Flipin ) Heck is this well we all assumed the censor lead even me

Wrong . . .

Any way back home and its round 2:30AM . . . yea I dont sleep to good and me pills kick in LOL ask Paul

Any way here it comes plug the leads in wrong way round into 1s Lipo . . . SMOKE



told ya these pills were good I just laughed LOL

and the positive lead de solders it self off the ESC . . .
yep de soldered it self hot or what any way I now need a New ESC and Smart boost



this is not going to happen again so I fitted a DIODE in between the corally plug and the new ESC Lead ( 1n5401 )


this 23 pence gismo saves ££££'s


As in above pic . . . solder the diode into the Corally plug ( make a note the silver bit up ) then fit heat shrink over Lead. . . solder lead to diode I then pull the heat shrink over the lot job done

WHAT A PLONKER

Any way talking to Marti and we think the diode should work I ran it around the garden this afternoon and seems OK so will try it out next meeting to see if it can take the current draw ?

well it worked

for 3 ninutes then went pop lol well back to the drawing board

Try some deans connector's then you would be fine!
(ps i know your lipo has 4mm corrallys built in)

Gazza try 3 1N5401'S in parallel ....?

Would it not be easier to make one lead too short to reach the opposing pole??

I had this issue with my dad plugging in corrallys the wrong way round, chopped one lead right down to minimum length to reach and hey presto problem solved.

A diode isnt the way forward on this, 1N5401 I think is 3A, no where near enough. Off the line I expect you will be drawing about 30A, I know my brushed G2 draws about 55-60A from the start line.
Thats alot of diodes!!! LOL

Blimey I forgot all about this thread

Yes mine is shorter now . . . forgot to post that thanks for reminding me

Good shout on the cutting the lead short. A very mardave style fix, simple but effective.

i'm not surprised. A basic 50p diode from Maplins will pop once you draw over about 3 amps.

easy way of not getting the connectors wrong is to hard wire a male & female conversion, perhaps change the length of the lead using a cable tie or heatshrink so the wires only reach the terminal they are supposed to thus making it impossible cross wire them or go mad with the red sticky-tape so you can see which wire goes where.
