Quick connector for two 18560 in parallel

[Bjerknez]

I have plan to use two 18560 cells in parallel for powering my Wemos D1 Mini (with a voltage regulator thar regulate the voltage down to 3.3V ofcourse). I want to connect these two batteries together in that way that i easy can take them apart for charging them individually in my Xtar Dragon VP4 Plus Charger.

I know how i connects it, but want som ideas for how i can make an quick connection that connect two 18560 together in parallel.

My first thought was to use a battery holder with two slots and solder wires and connector to that. That way i can just pop out the batteries and put them in the charger.

But i want an more compact and safe way to do it. I just looking for som ideas to quick connect/disconnect two batteries in parallel without soldering or messing too much with the battery terminals that makes it harder to put them in charger later.

Some ideas?

Make a ‘Y’ cable using JST type connectors.

But can you be more spesific on how you would use that cable? I know the wiring is simple. i understand that part. I just want to see how you thinking using the cable for the most compact design?

Top male connector goes to the load.

Bottom left female connector goes to Battery #1 male connector.

Bottom right female connector goes to Battery #2 male connector.

---

Unplug 1 and 2 from the associated male battery connectors to isolate the batteries from each other.

Plug battery #1 male connector into charger . . .

Obviously you can make the wiring short as you need.

For charging make extension cables if needed.

You can buy these too.

Thanks larryd

But i have read a lot about using two or more 18650 cells in parallel now and i am very unsure how danger this is.

Is it safe to use two (or more) 18650 cells in parallel when i use similar batteries charged to full in same charger or not?

Let's see your battery charger.

The circuit you are designing would have the cells in parallel i.e. when they are being 'discharged'.

For charging, you either use a battery holder as seen in post #4 and remove the cells (when being charged) 'or' would make a dummy cell that would connect to the projects tabbed battery cell’s ‘Y’ cable and plug that dummy cell in the charger.

However, we need to see a link to your charger.

Thanks to larryd regards to the cable tips.

Now, i have made one my self, with XT60 connectors.
