Battery for toy drone

Hi Alex,

You are correct. It is definitely a jst-ph connector.

But I am not having the greatest luck on this. Charger delivered yesterday. It has 12 ports:

6 x 2.0 (I think)

6 x 1.25 micro (I think) Both of these sizes are jst-ph connectors. Is that right?

I actually have 2 different toy drone batteries, one of these fitted the larger port, and the other, the smaller. I plugged in the smaller one (the one I am actually trying to get sorted and which the photos in the thread refer to. the 1.25? ): Result: a green led light flash and nothing more, despite several hours of repeated attempts to charge, I then tried the battery in the drone: Flat as a pancake.

I then tried the battery with the larger connector (2.0?): Immediately a constant red light came on, and stayed on for 30 minutes, then went out. Then tried that battery in that drone: Result: fully charged.

So… Have I bought a charger that works on the larger port, but not on the smaller? Highly unlikely, I’ll wager. Otherwise, the battery with the smaller connector is naffed and I need to get a new one.

Photos attached and very grateful for your advice whenever you get a chance. (Photos poor I know. Can send better if this helps).
