People use deans to prevent accidental polarity reverse on Lipo which eventually kill the batt. However there are LiPo which comes with dean.

In this case just replace the dean on your ESC end.

Yes you can, just be sure to solder females on your batteries and a male on your esc

You run the risk of shorting the batteries with the male deans on the battery side. If the 2 exposed pins touch anything metal bye bye battery. It could happen transporting them to the track and then you'd have a nice melt down/fire on your hands.

For safety it should always be female on batteries and male on esc.

I suggest you unsolder the plug on your esc and put a male there and change your batteries to female.

Well in short if you are expert in soldering electronics. That would not be an issue. But for me safety comes first.

to address the "fat wire" issue, You probably have seen deans soldered where the one of the wires is on the "inside" of the metal tab soldered. I think that is what you may be having issue with, trying to see that could still fit there.

If so, just solder the wire on the other side. This is what I do with my packs for the really fat wire ones., then run either heatshrink on the wires, electrical tape, or even electrical liquid tape.

Another tip, when you are soldering the wires and a live pack is corrected to the wires, one trick avoid bumping the wires together is to wrap the unused end or completed end with a tiny bit of electrical tape.

Or just don't strip both ends at the same time.

Pre-tin the wire and the end of the connector you're going to solder to. This makes it much easier to complete the job without overheating the connector.
And have a friend help you (or at least servo tape the connector to workspace so it doesn't slide around when you're trying to solder it). A set of "helping hands" would work as well.

Don't forget to put the pieces of fresh shrink wrap on the wires before you solder the connector on, or you won't be able to do it after it is assembled. Slide them down the wire away from the end you're soldering so the heat from the soldering process doesn't cause the shrink wrap to start shrinking.

With thick wires on Deans, use a decent quality soldering iron with enough wattage. I have a pretty good 45w solder station, but I prefer my 65w to get the deans on fast without over heating the connector.

( I have ruined a few Deans by keeping a low wattage iron on the wire for too long getting the solder to flow)

40 watt is more than enough power to solder deans plugs. Tin both wire and tab on plug and be sure to use flux and and there will be no issues. I have soldered countless deans plugs with a 40 watt iron and never had any problems.

a buddy of mine had an issue with just using the wire covering as he so how touched the wire inside and gave himself a jolt. So after that, I have just been wrapping them in electrical tape regardless.
