Si, the "standard name" (at least here in the US) is JST PLUGS. I don't know what that means but that is what r/c guys call them and you could walk into a hobby store and ask for them. Now, I have seen "Mini" and "micro" JST plugs but the regular ones that come on Li Pos, etc. are just JST. Corn-fusing? Hell yes.
That's why I get rid of the damn things and solder on MINIATRONICS 2 PIN MICRO PLUGS. These work well, are very small and once again, I have used them for many years. No, they ain't real cheap but YOU GET WHAT YOU PAY FOR.

Howdy Woodie :cb:



It was a bit of a long slog ...

... but EVENTUALLY the LiPo connectors were found.



There does seem to be some confusion over the 'proper' name for some of these things.

I saw a number of eBay listings which were contradictory & basically WRONG.



The connector on my LiPos ( with the 2 side-wings ) & charger is called a ...

'LOSI micro T 2.0'

or

'Walkera micro 2.0'

They should be found eventually on eBay, using these search-terms.

The 'side-wings' confirm that the connector is correct, as I see no other connectors that have them.

I found a deal on 10x wired plugs & 10x wired sockets, for £1.26p inc. P&P

Also 10x plug & 10x socket shells with crimps, for £2.08p inc. P&P

I did have to search rather hard to find a good deal, as these connectors do seem to go for some dough.



I also got some JST 1.25mm pitch wired plugs & sockets as well.

These are I believe are also sometimes known as Molex micro-blades'.

This type of connector is used by Bachmann & Hornby a lot, so I discovered.

These are EASY to find & very cheap indeed.

You can get JST 1.25mm shells with crimps, but do they look tiny ? ... Yep !



I was impatient on the JST 1.25 ones & actually flashed some cash for a bunch next day.

The LOSI/Walkera 2.0 ones are coming from Ying Ping Jing Pong Provence & could take a while to get here.

However I only need 1 per loco/installation, whereas the JST 1.25mm ones, I will use for LEDs, motors & the cigar lighter !

Meanwhile I can 'bodge' the battery hook up ...

... no sweat. I've got a fire-extinguisher & asbestos underwear ! ;)



:moose:



Si.



Need some other jazz, like really small heatshrink-tubing ...

... but basically, I have got all the parts ! :bg:

Now to get down to busting & burning 'em out !! :shocked: ;)

Here's the link to the LiPo & charger, sockets & plugs, at a very good price ...

... £1.26p inc. P&P for 10x wired sockets & 10x wired plugs.


LOSI micro T 2.0 / Walkera micro 2.0


They are the ones needed to connect with this type of LiPo & charger connector.

The JST 1.25 AKA Molex is commonly used for battery connectors too, the ones with the connector mounted on the battery for example. See for example
http://www.micronradiocontrol.co.uk/lipo_um.html

Be careful though, this pattern of connector comes in various sizes and they are all described as JST!

I have tried the do-it-yourself crimped ones, I got about half connected, the others just broke in the process, you need the proper and expensive crimp tool for this to work well. The ones with wires attached are best if you don't have the tool.

Those who know how to solder might try this variant ( from the same website )

Those are very useful and easy enough to solder, it's the connector that plugs into that one that I found difficult.

http://www.micronradiocontrol.co.uk/images/gen/micron/mrc-molex-3pin-conn-5pk_500.jpg

This one crimps together and needs the proper tool. It's a lot easier to buy the ready wired version, eg.

The Molex and JST connectors are not interchangeable, even if they can be connected with some fiddling. Even Wikipedia notes that JST-GH is sometimes confused with Molex Picoblade.
I use eFlite 150 and 70 mAH batteries, they have Molex connectors. The connectors with pins (blades) are not too difficult to solder wires onto, the sockets are near impossible (for me) so I buy them with wires when I need them.

Hi Guys :wave:


Thanks for the info.


My JST-GH 1.25mm pitch wired plug/socket connectors arrived.

I can't say that I'm exactly overjoyed about them ...

... which I had a feeling would be the case.


I would like to really use 24awg cable.


I may well investigate the 2.00mm pitch JST-PA series ...

... I don't particularly want a 'locking' connector either.


My preferred connector pitch has always been 0.1" or 2.54mm

I use both standard MOLEX and one called AMP-MODU already.

They are somewhat largish, I can easily hand-crimp the terminals though.


The principle problem with soldering a flexible wire connector, is the copper becomes easy to break at the join.

The second problem is that most of the connectors can't take heat at all well.

If you want one that can, go for something made from glass-reinforced plastic.


I would however use the JST-GH 1.25mm for LED headlamps perhaps ...

... so they probably won't go to waste.


I may well check out the Miniatronics-micro as well.

I would like to just 'standardize' on this & then forget about it, so a good decision is needed.

I may even just stick to the 0.1" systems I already use for various audio stuff.

The LiPo connector will be the 'standard' LOSI Micro-T 2.0 for sure  .  .  .

For the uninitiated, like me, does it really make a lot of difference which type of connector you use?

Michael,

The main thing is that you need the right connector for the batteries you are using. As there are several different but apparently similar connectors, you need to make sure you have the right one. Best thing is to get the batteries and connectors from the same supplier.

I use the same connector for the battery and for a charging connector, that way there is only one type to worry about.
