Adapters for JST SM 3 pin to XT60?

Hello to all.

Brand new to the hobby, I bought a Land Rover D90 MN99s (yes, I know that some may not consider it an hobby grade vehicle :) ).

It has this weird USB charger to charge a jst sm 3 pin battery...

I have an HOTA D6 PRO that has XT60 plugs and I can't find an adapter to charge this battery

What can I do to start using the HOTA D6 and not the USB charger?
This battery only has 1 cable with 3 wires and what I usually see is at least 2 cables, one other for balancing (I believe...)

Thanks in advance.

You could snip the plug of the standard charger and use it to make an adapter, and also make another adapter so you can still use the standard charger as well.

I suspect that with a battery that small, you would just charge using the balance port and nothing else.
 
Thank you Outlore for your reply.
I'm really a newb so, I'm really not into soldering and cutting electrical wires at this stage!!! :)

I'm not sure you'll be able to buy an adapter readily made out of the box, as the demand for it is going to be low.

What you could do is contact the battery/charger resellers/specialists (SMC Racing is one that comes to mind) and see what they can do to help, or maybe someone here can help you out. Might also be worth looking for a local group via facebook or some other social media where someone local may be able to make what you're looking for.

Soldering & wiring is a useful skill especially within RC, but also has uses outside of the hobby, so if you get the chance to learn and get the kit I'd go for it.
 
In order to start using a "real" charger like the one you mentioned, your harness needs to do two things -

#1: provide a balance lead
#2: Provide a main power tap

The way that battery is configured makes that slightly more complex but it can be done.

You need to create an adapter that will transform those three wires into a proper balance tap (JST-XH I believe it is, the common white one seen on most batteries) and then from those three wires, you need to create a circuit that reads from wire only #1 & #3 in order to read the full pack voltage.

If you're not comfortable with cutting/splicing/soldering than I highly doubt you will find this adapter ready made, you'll need to either make it yourself or find someone that's willing to build you a custom harness.



*Everything I've said is based on assumptions made because of only seeing the battery in one picture, circuits and polarity's should be confirmed with a multimeter before any attempt to fabricate a custom harness.
 
thank you both for the replies!
"thumbsup"

yes, I believe that there is no out-of-the box adpater for this...
 
It would be something like that, but I don't know if that one's right.

Contact the user HeyOK on this forum, Ferp is right and he's the perfect guy to talk to about having one made. He has several thread in the Electronics forum that you could use to find him.

You going into uncharted waters here so I recommend not trying to jerry-rig a solution but have something made by someone who is confident that they understand exactly what you need.
 
That's not the same plug but I wouldn't be surprised if it worked as. The pins are a fairly common size and spacing. It just won't be keyed for polarity probably
