GPToys Foxx S911 older battery

[netmatt]

Hi, I have an older GPToys Foxx S911, and the batteries for it are now dead. I looked up new ones but the connector has changed. Mine say :

Li-ion F1601
16500/800mAH 9.6v

They have a 2 pin (square/circle) male connector (similar to airsoft batteries, if you are familiar) Here is what it looks like:

(note the link in that one goes to Gearbest where they are selling the other one...)

All the ones I find on sites are like a 4 or 6 pin, its hard to tell. (new standard battery is at the start of this video):

Can I still get batteries for the ones I have, or something that works?

It would be best if you changed the plug on your ESC to fit the batteries you're able to get. They're very easy to solder on just make sure to get the polarity correct.

I can do that, is there a recommended battery to use, that is common, and 2-wire, which would be a good replacement?

That's called a Tamiya connector. It is a low amperage connector. I would look for something with a EC3 or a Deans connector. Then when you find the battery that you want you can change the ESC to that connector.

I've seen a few that have a Uni 2.0 Plug like this: https://www.amazon.com/Venom-1300mAh-Battery-Compare-EFLB13003S20/dp/B016ZM2Z1I/

Would something like that be an alternative?

In addition to that Uni Plug thing, here is another question

My kids like Airsoft, and given we have 8.4v, 9.6v and 11.1v airsoft batteries (typically NiMH, but one Lipo), and all use the Tamiya connector would it be safe to connect one of those to the car, to see if it works? I dont want to burn out or short something by testing it, so I figured I would ask first.

OK, as far as airsoft batteries, just in case anyone searches and finds this...they are wired opposite of the cars. So watch the red/black (pos/neg) orientation.

I did switch the pins and the car worked...to an extent.

The remote seemed to drop in and out...the connection light was solid, but then started blinking, solid, blink, etc. It would go, but only if I applied a "little" bit of speed. Now I am wondering if the latter was because the airsoft battery was 9.6v 1600mAH, and the original battery was 16500/800mAH 9.6v ...maybe I was overjuicing it with the newer battery? Once I pulled the trigger more than a little, the car started to stutter and would not go.

Thoughts?
