Default Connector Adapters

Not owning a soldering iron and not wanting to own a separate parallel charge board for each connector type (I have an EC3 parallel board)---Is there any downside to simply using commercial adapters to charge non-EC3 (XT60 for example) batteries on the EC3 board? Also, what is the thinking on using adapters inside the plane to connect battery to ESC? Thanks. Gary

The only down side when charging is the added potential failure points... with extremely low failure rate.

I use adapters all the time.
I tend to make my own adapters but using commercially made ones shouldn't be an issue.

Eventually you may want to buy a soldering iron. They are relatively cheap and come in handy.

Thanks fhhuber. What do you think of the second part of my question---using adapters inside the plane to connect a deans plug to an xt60 battery? Is this simply adding to the possibility of a bad connection? Also, what wattage soldering iron is necessary to do this type of electrical soldering?

I have both Deans and XT60 fitted gear / batterys ... and think nothing of using either with either. As long as the adaptor makes good contact and not loose ... it's fine.
I would avoid such on a very high AMP demand installation though ... but usual sunday sport stuff of the up to 30 .. 40A variety should not be a problem.

Soldering iron ... a standard 40W or higher domestic iron with a choice of pointed and flat spade end tip.
A small soldering station of Iron, stand and wipe mat can be bought at local Radio Shack and similar for small money. Add in a roll of standard ROSIN solder and away you go.

Using the adapters inside the airplane works fine too. There is a SMALL added resistance because of the extra connections. You'd have to do careful testing with a wattmeter and motor test stand to see the power difference.

I have a deans to 4mm bullet adapter in my big EDF. The EDF came with Deans (for a motor expecting 100 amps continuous...) Changing that connector would have voided the warranty on a 1400 EDF unit. (yes, I called BVM and asked)

I went with a 100 watt high temp iron so I can solder large gauge wire fast. The 40 watt irons take a while (never hot enough if using lead-free) when working with 8 gauge.

If anyone is looking for a quality, temperature regulated 100 Watt Soldering iron, this one fills the bill.

And, for soldering smaller stuff like balance cables and so on, I've picked up one of these. This unit works extremely well.

Stay away from those 100 Watt Soldering "guns" though. Trying to solder #8 wire with one of these could be a lesson in frustration. These type soldering guns have two temperatures. Way to hot when not soldering anything. And, way to cold when soldering heavy conductors like #12 or so. I've measured over 1000 degrees F on one of my soldering guns 30 seconds after pulling the trigger.

IMHO, NOT a good choice

I make/use adapters all the time for use in my planes. I've never had an issue.

Adapters aren't really a problem. Unless when you've got several inside a model, and you run out of room for the wiring

I think I have every possible two-way adaptor config. Use them all the time. No issues. I'd be at a loss without them. And my paraboard for my I-charger can handle ec3, xt-60 or deans.

For the price of several connectors, you could.buy another.charging board....

slow stock prop reversal. it flies! easily! 543 watt dual motor bipe slow stick. push-me-pull-you. 242 watt 3 channel slow stick. 365 watt mini ultra stick. 415 watt mini contender. 810 watt ultra stick .25e. 220 watt alpha 450 sport (retired).
