So I went to plug in my batteries and do a storage charge. Started inserting the deans and pop/flash. The parallel lead from the charger, male end and SECOND time this has happened to me. First time the connectors were ruined and I thought some how I crossed or tried to insert + to -. This time it appears the + spring touched the - post.....but how?? So weird, I didn't mate them wrong, but this is what happened.

Thanks for your thoughts

I use deans all the time on my small to 600 helis. I narrowly missed what happened to you a lot of times while plugging up my 12S and 6S helis. I really never did understood why T Plugs became so popular, maybe because they clean themselves when you insert them?
They are difficult to solder for most people and are not shielded on both ends. A lot of people get it wrong and lose power because of improper soldering with Deans plugs. XT60's, EC3, EC5, and prc6 seem more logical to me, even the banana plugs that come on my lipos are safer to work with.

Sooo
I guess I am wondering if the 'spring' can wear to the point of bending while be inserted??? I am switching everything over to Anderson Power poles, but just want a confirmation this can happen!?

No not wear, it just a design flaw. You see when you solder the plugs on, that heat warps the plug and make the spring increase its distance from the other half. While plugging in the T plug the spring gets separated continues to travel towards the opposite pole, creating that wonderful welding light.

If you use female plugged onto the end of the male while soldering, it will keep the spring from doing that and also help keep the plug cooler if you're not very good at soldering.

Spark
The spark is not unusual. There's an inline resistor you can fit to stop that. Without it, any connector will show pitting and wear over time. But the larger metal pieces will last much better than those thin tabs. This includes the "original style" EC-5 connectors. If they are slit open like a banana plug, you're gonna to eventually find some of the pieces missing and burnt away. My preference are the newer, mor solid EC-5 connectors. But what do I know?

Good flying.

Seen it had it happen often enough to never use them, havent for years now. For small 6S and under XT60 now and anything larger in voltage EC5.

Deans were good, "back in the day" low voltage stuff, still "ok for 2-3S" but imo its old school and there are much better options now days so why bother...

...Once upon a time there were Nitros, flybars and frequency pins...

Get the plugs straightened out, and be carefully while inserting.
It needs special attention while plugging in...but the plugs work great for me FOR A CERTAIN SIZE OF BATTERIES.
For larger ones I use 8 mm EMCOTEC plugs...and for smaller batteries I use again EMCOTEC plugs...the green ones.

Deans are fine for 3s. For 6s and above, get yourself some EC5s.

YES, it happens.

It's the wrong connector for given application.

They are only rated up to 50A.

Number of cells is irrelevant.(up to a point)

Its the AMPerage rating that needs to be matched.
