Questions?? soldering direct to battery

does it really make a difference to solder your battery direct to the speed control than just using deans

It shortens the life of the last two cells in the pack due to the heat it receives everytime you solder the wires on it.

well it might be a little more better connection over running deans.

yes, less connections. not as much loss of current. less resistance but the gain is minimal from what i have studied. The possible gain in performance over a Dean's plug is less than 0.3% at 40 Amps current draw.
only downfall is that you have to bring your soldering iron everywhere with you. hope this helps

That would be true if you left the thing on for 30 seconds and let the heat go from the bar to the battery, but who does that?

Once you can run a heat or main without a crash or bobble then you can worry about voltage drop. Unless you are 3 tenths of a second from TQ at the worlds deans plugs are fine. Just my 2 cents.

That's what I think as well.

Do you solder your motor in?

For me, its just one less thing to worry about...... Coming unplugged that is......

We tried both ways and seen no difference on the track. I've never heard of a deans plug disconnecting, a bad solder job on the plug or bar will end your race.

i agree, the gain is minimal. i also would say don't worry about it unless you are a major national racer or even a top state racer. deans plugs are great and i have never seen them disconnect nor overheat. just stay away from tamiya connectors.

I have been direct soldering for 20+ years and have never had a problem with the last to cells in a pack, as someone else said it may if you hold the soldering iron on to long.

The advantage though is minimal. Years ago when I started connectors were not what they are today. With the low resistance of a deans connector you will not be able to tell a differance.

The only reason I kept on direct soldering is that I feel I can lay the wires out a little shorter and cleaner looking but now that I have switched to lipos my soldering iron has gone into semi-retirement
