Li-Po connectors are a personal preference in my book Alex, nothing wrong with Deans connectors but some will say they can be tricky to solder and plug together/apart.

I have used 4mm bullet connectors with all of my Li-Po's with a light sprinkling of Deans here and there.

Alex, you will get 10 replies all recommending 10 different options!

I personally use Deans because I made that decision a few years ago and have standardised on everything - chargers, ESC and all batts are now interchangeable.

To be honest - if I was starting now I'd probably go for the XT-60 connectors. They are a bit easier to solder than a Deans.

You'll also read that most Deans are Chinese copies. They are - but I have never had a problem with them.

There are some useful YouTube videos about how to solder them.

Thanks Allan, I've got a dozen or so battery's and have a mix of connectors and charge leads... So I was just gonna make them all the same connection, deans seem to be the better option fr the sake of parallel charging but I'd also read that the solder connections can be dodgy but I guess that can be said for any soldering :D

I'm with Alex. In my early years I used bullets on my NiCads etc, but after a bit of a layoff I came back and started using Lipos, and the first one I bought had a Deans fitted and I have used them ever since. But I was starting now i think that I too would use the XT-60.

Deans, apart from the sometimes awkward location and jamming, poor grip (even the clone ribbed ones) and awkward insulation after soldering, have a history of arc and burn failure in the large EP Heli world that has lead all the very experienced members of my club to dump them long ago. This may not be an issue at 3S but certainly is by the time you get to 5S and above.

I use 3.5mm Bullets, but then I don't have EP above 6S. Differing manufacturers have differing ideas on what constitutes 3.5mm, so nothing is perfect, but they do allow easy but positive connenction/disconnection, esp where bulk is an issue and its handy to have positive and negative apart due space, cable routing, etc

As has been said...ask 10 aeromodellers & you'll probably get 11 answers!!!

Hi Alex,

I started off with Deans, then changed to XT60's, but now use EC3's or 5's depending on the thickness of the wire, the advantage to these is that the connectors are soldered out of the plastic body and then snapped into place so you do not run the risk of melting the plastic body.

I use Deans Ultra, and like them because they can't be mis-connected, and for their small physical size. I'm not sure why they should arc and burn any more than any other connector, and haven't found that to be a problem in any of my models.

The key, as with any component, is to operate them within their specified limits. On all my models, from 3S A123 up to 12S LiPo I operate at less than 45A, and on my 12S models I use spark eliminators.

I use XT60s on everything up to 100A. Above that I use shielded 4mm bullets as they'll take the amps better. I tried Deans but didn't get on with them- I ended up trying to prise them apart from metallic objects- not the best!
