Thought I'd ask here as you guys have a lot of experience with this stuff.
I'd like to get or configure an adapter so I could use my 'Good' battery charger to charge the batteries that came with my 903a truck. They have an adapter that is described as a 'T' on the leads to connect it to the truck.

What I would like is an adapter that ends up looking like this:

I have an adapter to put on that end so it can hook up to this connector on the battery charger:

Where would I find the pieces to do this?
Thanks in advance for any help.
 
Can't tell if that's IC3 or IC5, but you can find adapters on Amazon... these are for EC3 (same size as IC3, but without Smart center pin)

Adapters

If you're running on more than 3S, I'd hardwire a new connector instead.

You can also flip that little cover up to get another port, since I think that's EC5 and there's EC3 underneath it.
 
I am aware of that, but thanks for responding.
Standardization goes a long ways in the enjoyment factor of a hobby. Being able to use my 'Good' battery charger on all of my batteries will be a bonus.

Definitely. I went all XT60 for mine, seems to be the most versatile choice.

I'm wary of those battery adapters with a bit of heat shrink between the plugs, that tells you they're just two plugs soldered directly lug-to-lug, often rather poorly, sometimes backwards.

There's single-peice adapters out there that are a solid conductor with no soldered bits, I couldn't find any for EC3/5 to Deans, (T-plug), but I went all XT60 for my logistics since that seems to be the most universally supported and cost-effective.

I have a couple of those too and use them for the batteries for the Mojave. They do work well. I'll check the others with my VOM to be sure they're correct before using them on the other batteries, when they get here.
 
Ahhh, the subtleties of the rounded end vs the sharp angled end, got to keep an eye open for that.

So I don't clog up another thread, I'll just add to this one.
I bought a battery bag the other day. I was concerned when I found a battery I'd charged up the day before was warm to the touch. I've never had my camera batteries do that after charging once they're done. So, I bought the bag and will keep them in there. While I was packing I thought it might work as a tool bag too. So all tools and charger related items will go in the bag as well.

I prefer to ditch the T/deans connectors altogether in favor of xt60,xt90, or bigger if necessary. I pick a connector I want to use across the board on all my rc’s, and that’s what I solder onto my ESC’s, batteries, and also make charging adapters accordingly.
I like the xt’s, some people like the ec/ic’s. The most important thing is to have a connector that is rated for the amps being delivered to the load. Don’t let the connector be the bottleneck. Oversizing connectors isn’t a bad thing. One of these days I’ll switch out to the QS8 or whatever it’s called.

Clog another thread? There's none of that going on in the forum.
Sarcasm. Clogging/thread derailment is common 🤷‍♂️ :( :)
Sometimes it's the health of the cells, and/or how fast you are charging that can cause cells to become warm. I'm not going to get into it here, but in some racing situations, a person may feel the need to intentionally warm cells by doing some over the top charging practices for small gains.

If you're going to use Deans connectors, you should use the real Dean Ultra Plugs. They can handle a lot more current than the generic Chinese "T" Plugs.
